This change consists of multiple changes:
Core:
- Deprecation of ANY_PACKAGE macro. Added ANY_PACKAGE_DEPRECATED macro which can still be used for backwards compatibility purposes (only used in CoreUObject)
- Deprecation of StaticFindObjectFast* functions that take bAnyPackage parameter
- Added UStruct::GetStructPathName function that returns FTopLevelAssetPath representing the path name (package + object FName, super quick compared to UObject::GetPathName) + wrapper UClass::GetClassPathName to make it look better when used with UClasses
- Added (Static)FindFirstObject* functions that find a first object given its Name (no Outer). These functions are used in places I consider valid to do global UObject (UClass) lookups like parsing command line parameters / checking for unique object names
- Added static UClass::TryFindType function which serves a similar purpose as FindFirstObject however it's going to throw a warning (with a callstack / maybe ensure in the future?) if short class name is provided. This function is used in places that used to use short class names but now should have been converted to use path names to catch any potential regressions and or edge cases I missed.
- Added static UClass::TryConvertShortNameToPathName utility function
- Added static UClass::TryFixShortClassNameExportPath utility function
- Object text export paths will now also include class path (Texture2D'/Game/Textures/Grass.Grass' -> /Script/Engine.Texture2D'/Game/Textures/Grass.Grass')
- All places that manually generated object export paths for objects will now use FObjectPropertyBase::GetExportPath
- Added a new startup test that checks for short type names in UClass/FProperty MetaData values
AssetRegistry:
- Deprecated any member variables (FAssetData / FARFilter) or functions that use FNames to represent class names and replaced them with FTopLevelAssetPath
- Added new member variables and new function overloads that use FTopLevelAssetPath to represent class names
- This also applies to a few other modules' APIs to match AssetRegistry changes
Everything else:
- Updated code that used ANY_PACKAGE (depending on the use case) to use FindObject(nullptr, PathToObject), UClass::TryFindType (used when path name is expected, warns if it's a short name) or FindFirstObject (usually for finding types based on user input but there's been a few legitimate use cases not related to user input)
- Updated code that used AssetRegistry API to use FTopLevelAssetPaths and USomeClass::StaticClass()->GetClassPathName() instead of GetFName()
- Updated meta data and hardcoded FindObject(ANY_PACKAGE, "EEnumNameOrClassName") calls to use path names

#jira FORT-59762
Change 3779062 by Mike.Fricker
Merged CL 3731188 and CL 3733311 from //UE4/Dev-Editor.
----
Improve responsiveness of Open Asset dialog.
On large projects, there's a noticeable delay when opening and searching/filtering assets.
Stopwatch measurements on my machine (seconds for ~122,000 assets):
before with this CL
ctrl-P 1.4 0.45
search 1.8 0.55
CollectionManagerModule was the main culprit for search/filter slowness.
Open Asset delay was due to filtering out plugin content. We were doing a lot of redundant work for what is essentially a read-only operation.
Change 3778954 by Nick.Darnell
Slate - Making the Horizontal and Vertical analog keys configurable in the navigation config. Tweaking how fast the navigation is with the analog stick, trying to tune the feeling.
Change 3778896 by Ben.Marsh
Separate FNameEntrySerialized from FNameEntry, rather than deriving from it. It has to be allocated differently, and many fields cannot be shared between the two.
#jira
Change 3778807 by Ben.Marsh
Fix Tencent include paths not registering if workspace directory contains a space.
Tencent include paths currently have a trailing backslash, and this is surrounded by quotes if the root directory contains a space. The backslash is interpreted as escaping the trailing double quote.

Change 3778686 by Luke.Thatcher
Reduced impact of dynamic vertex buffer RHI stall in D3D12
- In most cases we can avoid the stall if the vertex buffer has never been used before.
- Only when a buffer has an existing SRV do we need to stall.
- Also, delete copy and move constructors of FD3D12ResourceLocation. Moving or copying an instance of this class leads to double free crashes, so this is now a compile error rather than a runtime crash.
This saves an average of 2ms frame time in a StW lastperftest replay, with r.screenpercentage 10.
#jira FORT-61390
Change 3778679 by Thomas.Sarkanen
Fix Linux server crash - dont attempt to run threaded work in a single-threaded environment
We dont attempt to run animation update work multi-threaded in the same conditions that we didnt attempt to run animation eval work previously.
#jira FORT-61548

Change 3778175 by ben.marsh
Remove code to trigger an ensure on Arxan guards. We already send analytics for this, and don't need this legacy path. There is a large number of incoming ensures with this callstack that are clogging up crash reporter.
Will remove all the surrounding code in a later update to a development branch.
#jira
Change 3777750 by Chris.Gagnon
- Slate now supports a CustomBoundary Navigation type wich allows a custom handler if the boundary is hit.
- This provides the ability to have normal navigation while within the boundary and the custom function only on the boundary.
- This differs from Custom which is a full override of the navigation behavior.

Change 3774201 by Gil.Gribb
UE4 - Fixed rare crash caused by unmounting pak files.
Change 3773920 by Gil.Gribb
UE4 - Added experimental option r.StartPrepassParallelTranslatesImmediately which allows the parallel translate tasks from the prepass to start before we init shadows. Disabled by default.
Change 3773896 by Thomas.Sarkanen
Push non-rendered anim updates back onto the worker thread
Now when meshes are set to EMeshComponentUpdateFlag::AlwaysTickPose, we optionally kick of a task to perform parallel update only (no evaluation).
#jira FORT-61157 - Run anim update on worker, even if not visible

Change 3773011 by Robert.Manuszewski
Header (uasset) and export (uexp) files will now be compared seperately when running cook commandlet with -diffonly to avoid situations where a mismatch in size of the header produces more differences between exports.
+ Renamed ini setting to ignore header differences from SkipHeaderDiff to IgnoreHeaderDiff
Change 3772867 by Thomas.Sarkanen
Nativization now correctly generates and builds code for "Client" builds
Overall this is a bunch of hacks, but necessary for nativization to work at present. Once the cooker and UAT both have a concept of "Client" targets, this can be implemented properly.
Instead of building to a "Client" directory, we build to "Game" for client-only platforms (like PS4, XboxOne)
Also we need to add "Client" targets to the whitelist for the nativized assets plugin, as UBT still thinks it is building for "Client"
#jira FORT-52823 - Nativizing Player Animation Blueprints
Change 3772408 by Robert.Manuszewski
Cook commandlet will now report full property name when running a diff against the existing cook (-diffonly)
Change 3772359 by Thomas.Sarkanen
Improvements to the Cpp backend to allow VC++ to compile nativized code more effectively
Added a new scoped helper to wrap areas of the code in PRAGMA_DISABLE_OPTIMIZATION. This helps with functions that are large tables or long lists of initializations.
Split anim node initialization up into functions, called from a seperate function dedicated to initializing anim nodes. This splits the 5k+ line constructor into mutiple smaller functions, which the compiler has no problems with.
Overall (along with splitting up the anim BP into functions in the asset) this reduces compilation time for the worst-case compilation unit from ~11m 40s to ~2m 32s.
#jira FORT-52823 - Nativizing Player Animation Blueprints
Change 3771975 by Zak.Middleton
Fix character proxies doing up to two floor check when only rotation changes. Add some optional verbose logging to FindFloor() and ComputeFloorDist().
#jira FORT-61134
Change 3771421 by Ori.Cohen
Fix CIS
Change 3771052 by Robert.Manuszewski
Package diff improvements (-diffonly mode for cooker). Exposed max diffs to report to ini and added the ability to suppress header differences reporting as they are usually a result of differences in exports anyway.
Change 3771039 by Bob.Tellez
#UE4 Allowing use of -FPS in PGO profile builds
Change 3770747 by Ori.Cohen
Added missing stat named events for anim bp
Change 3769616 by Arciel.Rekman
UBT: Use response files for compiler when compiling for Linux.
- Some command lines are too long when cross-compiling on Windows, which is a problem for non-unity builds (or local changes that result in exclusion of checked out files from the lumped units).
Change 3769457 by Gil.Gribb
UE4 - Added eviction to r.DoLazyStaticMeshUpdate. It just removes 10 prims a frame in a rolling fashion.
Change 3769136 by Michael.Noland
Engine: Improve IsServerDelegateForOSS to allow it to use the play world during PIE even if no context was passed in

#jira OR-46341
#tests LaneMinionFXTests, monolith w/ full teams.
Change 3768504 by Thomas.Sarkanen
Duplicating CL 3758315 from Paragon:
Optimized PostAnimEvaluation when URO is skipping a frame with no interpolation. Skip unnecessary work.
PreEvaluateAnimation() is now only called if we're about to evaluate anims. PostEvaluateAnimation() is also called only if we have evaluated animations.
Therefore PostEvaluateAnimation() has been pulled inside of PostAnimEvaluation() instead of FinalizeTransforms.
Added a call to ConditionallyDispatchQueuedAnimEvents() in the event that we're not calling PostBlendPhysics because we have not evaluated or interpolated anims.
Added missing call to PostEvaluateAnimation() for PostProcessAnimInstance.
#jira OR-46341
#tests minion FX perf map, lane minion test map, monolith match with 2 full teams.

Fixes to enable auto-nativization for animation blueprints
For blend profiles in particular, I've added subobject support to the fake import table building for nativized assets:
- In FEmitterLocalContext::FindGloballyMappedObject, if we dont find the referenced asset then we traverse the object's outer chain if it is a subobject. We add it to UsedObjectInCurrentClass if we find its outer.
- Updated the structure used to build the fake import table to include a specified outer. Beforehand we assumed that all objects referenced by the import table were 'top-level'.
- Updated the fake import table building code in FLinkerLoad::CreateDynamicTypeLoader() to use the new specified outer if found. This asserts if it couldnt find the outer in the already-parsed dependencies (as it reverse-iterates). If in the general case thius turns out to be a problem we can move this to a two-pass system.
Disabled fast-path optimization when running a native anim BP, as native code is faster!

This causes bushes to be located in different places depending on what platform you were playing on.
1) Random number reseeds were happening as part of function arguments to FVector(), but function argument evaluation order is unspecified, and behaved differently on Consoles/Mac/Windows. Fixed this bug.
2) Strings used for foliage CRCs could use different character sizes on different platforms. Now we always use ANSI.
3) Strings used for CRCs could have possibly have different case. Now forced lowercase.

Dterministic cook issues reporting improvements
- Huge performance improvements
- Added new metric to the summary: NumberOfDifferencesInPackages
- Diff stats have their own section now (Package.Diff)
- When running with -diffonly there commandlet will not log the Warning/Error summary anymore
- Callstacks are no longer logged with instruction addresses
- Because callstacks are no longer logged with addresses I can collapse them for structures that otherwise would be split into multiple separate callstacks
- Callstacks, Serialized Object and Serialized Property are now indented
- Each asset is capped at 5 entries. If there's more differences, they'll be logged as single warning.
- Replaced \r\n with \n in the callstack log to make it work better with EC

- No effective change to engine yet. The defaults values enable the same default behavior.
- New CVar: "s.ForceGCAfterLevelStreamedOut" (Whether to force a GC after levels are streamed out to instantly reclaim the memory at the expensive of a hitch.)
- New CVar: "s.ContinuouslyIncrementalGCWhileLevelsPendingPurge" (Whether to repeatedly kick off incremental GC when there are levels still waiting to be purged.)
- New CVar: "s.AllowLevelRequestsWhileAsyncLoadingInMatch" (Enables level streaming requests while async loading (of anything) while the match is already in progress and no loading screen is up)

Slate - Adding a new optional parameter to direct routing for the widgets under the cursor in Slate Application.

UMG - Finishing the ability to add a "Custom" method for Navigation. Currently the editor implementation leaves me wanting, but it works for now. You can put the name of a function to call (needs to match a signature that returns a UWidget).
Change 3740207 by Nick.Darnell
Slate - Navigation attempts when the user claims they are doing custom or explicit, if those methods don't return a valid widget, we don't treat it like the attempt failed and fallback to default navigation methods. Instead we use it as a trigger to indicate that no navigation should occur and treat it like a stop.

Editor: Rewrote CallInEditor support and promoted it so it can be used on functions in any class, not just blueprints derived from AActor:
- CallInEditor used on native UFUNCTION() declarations will now show up without having to make a BP subclass
- CallInEditor can now be used as a top-level keyword in the UFUNCTION() declaration (e.g., UFUNCTION(Category=CoolCommands, CallInEditor))
- Now shows each function as a separate button, placed in the category associated with the function
- The button strip entry is now searchable by function name or tooltip
- Prevented operating on functions that have parameters or return values, which would crash before
- Removed the duplicate copies of properties placed in the Blutility section
- Added a scoped transaction around CallInEditor execution
- Allowed functions to be marked as CallInEditor in addition to custom events (currently we don't allow editing category or tooltip on custom events...)
Editor: Moved Experimental/EarlyAccessPreview details customizations up to UObject so it can be used on any class, not just actors/components

Change 3690547 by Ryan.Gerleve
Speculative fix#2 for a server crash/assert. If the timing is right, it's possible for the server to try to re-load a placed-in-map actor that was previously garbage collected. This was happening because CanClientLoadObject was always returning true for these (null) objects, even if the NetGUID corresponded to a map actor that shouldn't be loaded. Also added/improved some logging that will help in case this doesn't fix the issue.

Cache weak object ptr in FNetworkObjectInfo to avoid reconstructing one every time we need to lookup its actor channel.
#jira FORT-57156
Change 3690227 by David.Ratti
Added optional TWeakObjectPtr parameter to packagemap functions GetOrAssignNetGUID, SUpportsObject. This allows you to pass in a weak ptr for an object if its already created. If you pass in null, the functions will create them internally.
This fixes some common cases where we were converting the same object into weak ptr multiple times in a frame.

[~] Modify new frame syncing to reduce performance regression seen when the game is running over budget.
- Rather than forcing a flip sync after we kick off one frame early, we just continue to kick frames if we time out. This allows the game thread to get ahead when we're over budget.
- The game thread will naturally resync with the vsync when we return to being in budget.

Change 3671079 by Ryan.Gerleve
Fix an edge case where the PackageMap on the server would try to resolve objects from default NetGUIDs even if their outer has already been garbage collected. This could lead to a completely unrelated object being returned instead of null, leading to asserts and potentially other issues.

Optimize some low level details of UNetConnection::ClientHasInitializedLevelFor() and UNetDriver::IsLevelInitializedForActor(). Add cached WorldPackage for NetDriver to avoid repeated GetOuterMost() and Casts. Remove rendundant virtual GetWorld() calls, and mark UNetDriver's version "final" to let it optimize away virtual call. Made UNetConnection::ClientVisibleLevelNames a TSet instead of TArray, since it is searched frequently when there are streaming levels present.

- Been testing with this for a while now
- This change makes particle effects show up on the current frame's pose for skel meshes as well
Removed my StopAllMontagesByGroupName temp hack
CL 3383318
Delay dispatching of AnimEvents (Notifies and Montage Events) until after we receive an updated animation pose (if applicable).
This fixes AnimNotifies playing particle effects using a socket location using last frame's pose. Now they use the current frame's pose.
CL 3388506
Delay clearing of MontageInstances and triggering 'OnAllMontageInstancesEnded' until all Montage Events have been dispatched.
Also fix SkelMeshComponent ticking on dedicated servers when rejoining in progress.

UMG - Making it possible to cancel delays and all animations on widgets. Useful when destroying a widget and needing to stop any async state.
Change 3777612 by Zak.Middleton
Perf: Added option to CharacterMovementComponent to skip immediate forward prediction for proxies on the frame they receive a network update (bNetworkSkipProxyPredictionOnNetUpdate). This avoids all forward prediction sweeps and floor checks on those updates. Intermediate frames will interpolate with prediction. This can also be disabled globally with the CVar "p.NetEnableSkipProxyPredictionOnNetUpdate 0".
Added NetworkSmoothingDisableProxyPredictionForPawnLOD to force disabling full simulation for LOD >= this value (currently 3, so bottom 75 pawns). This takes precedence over current distance and view angle checks for prediction (mesh interpolation is untouched).
Change 3774338 by Ben.Woodhouse

Increase allowed time for movement substep duration.

Texture streaming optimization where a maximum texture resolution for each level streaming data is computed per view.
This is used to cull irrelevant levels and reduce the async task number of iterations.
The culled size is defined by the new r.Streaming.MinLevelTextureScreenSize.
This requires to remove primitives with big UV density from the level data.
Those primitives get moved to the dynamic lists.
This is controlled by r.Streaming.MaxTextureUVDensity

- DPI awareness is only set on windows in the editor now (still disabled by default)
- Fixed hit proxy calculation not working properly with screen percentage
- Developers can now register a delegate with SlateApplication to tell when a window's DPI changes

Added support for in-editor previews of localized game text
This is configured by the "Preview Game Culture" setting, and will automatically be active when PIE is running (the preview language is also passed to any standalone games that are launched via the editor). This preview can also be used in the UMG editor to preview widgets in different languages.
While a preview is running, all editable FText fields are locked-down (read-only) to prevent accidentally clobbering source data with translation data. You can also use this new lock-down feature to prevent any localization changes in your project (set "LockLocalization" to "True" under the "Internationalization" section of either your DefaultGame or DefaultEngine INI).
In order to allow the game translations to be used in the editor, we now map the translation to any package localization ID variants when the LocRes data is loaded (or when looking up a specific piece of text). This is needed as the LocRes files only ever contain the "clean" versions of the IDs (without the package localization ID the editor uses), and also means that we no longer need to gather the "editor-only" variants of the text within assets.

#jira UE-48167 profiler crash
Don't duplicate the graph data when rebuilding because that completely voids the OneToOneMapping mechanism, resulting in the crash. Looking up objects in the mapping would always return null because the mapping contains the old addresses, before the rebuild.
One option would have been to completely rebuild the mapping according to the duplicate graph, which would be dubious because the duplicate method isn't specifically designed so that the result would replace the source.
But it looks like duplicating the data is not needed, it's safe to rebuild in-place, RebuildForFilter() doesn't do anything illegal with the objects. This is also the only purpose and the only reference of the function.

Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.
[CL 3209342 by Ben Marsh in Main branch]
* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.
