Prepared direct attribute access for deprecation, preferring use of APIs to access static mesh attributes.
Fixed recently merged Enterprise code to comply with new APIs.
Changed all tools to use triangle-centric iteration where possible.
Added new MeshAttributeArray APIs for querying attribute flags, and added a new Mandatory flag.
Various bug fixes.

[CL 13873755 by Richard TalbotWatkin in ue5-main branch]
- Removed hardcoded element type arrays (Vertices, Edges, Triangles etc.). Mesh element types can now be arbitrarily added, with any number of channels.
- Mesh element containers have a much leaner format; instead of sparse arrays, they are now represented by a simple bitarray, determining whether an index is used or not. Consequently, mesh topology is now entirely described with the attribute system, e.g. edge start and end vertices, triangle vertices, etc.
- Support added for attributes of arbitrary dimensions, e.g. float[4] or int[2].
- Support added for attributes which index into another mesh element container.
- Added FMeshElementIndexer: this is an efficient container for maintaining backward references from one element type to another; for example, edges have an attribute specifying which vertices are at each end (an attribute of type FVertexID[2]). With an indexer, it is possible to look up which edges contain a given vertex, even though this is not explicitly stored. Indexers are designed to do minimal allocations and update lazily and in batch when necessary.
- Added support for preserving UV topology in static meshes. UVs are now a first-class element type which may be indexed directly from triangles.
- Added the facility to access the underlying array in an attribute array directly.
- Triangles now directly reference their vertex, edge and UV IDs. Vertex instances are to be deprecated.
- Changed various systems to be triangle-centric rather than polygon-centric, as this is faster. Triangles are presumed to be the elementary face type in a MeshDescription, even if polygons are still supported. The concept of polygons will be somewhat shifted to mean a group of triangles which should be treated collectively for editing purposes.
- Optimised normal/tangent generation and FBX import.
- Deprecated EditableMesh, MeshEditor and StaticMeshEditorExtension plugins - these are to be removed, but they still have certain hooks in place which need removing.

MAJOR FEATURES & CHANGES
============================
Change 3805828 by Gil.Gribb
UE4 - Fixed a bug in the lock free stalling task queue and adjusted a comment. The code is not current used, so this is not actually change the way the code works.
Change 3806784 by Ben.Marsh
UAT: Remove code to compile UBT when using UE4Build. It should already be compiled as a dependency of UAT.
Change 3807549 by Graeme.Thornton

Removal of some unproven code which was supposed to fix hot reloading BP class functions in plugins.
See: https://udn.unrealengine.com/questions/376978/aitask-blueprint-nodes-disappear-when-their-module.html
#jira UE-53089
Change 3820358 by Ben.Marsh
PR #4358: Incredibuild use ShowAgent by default (Contributed by projectgheist)
Change 3822594 by Ben.Marsh
UAT: Improvements to log file handling.
- Always create log files in the final location, rather than writing to a temp directory and copying in later.
- Now supports -Verbose and -VeryVerbose for increasing log verbosity, rather than -Verbose=XXX.
- Keep a backlog of log output before the log system is initialized, and flush it to the log file once it is.
- Allow buildmachines to specify the uebp_FinalLogFolder environment variable, which is used to form paths for display. When build machines copy log files elsewhere after UAT finishes (eg. a network share), this allows error messages to display the right location.
Change 3823695 by Ben.Marsh
UGS: Fix issue where precompiled binaries would not be shown as available for a change until scrolling the last submitted code change into the buffer (other symptoms, like de-focussing the main window would cause it to go back to an unavailable state, since the changes buffer was shrunk).
Now always queries changes up to the last change for which zipped binaries are available.
Change 3823845 by Ben.Marsh
UBT: Exclude C# projects for unsupported platforms when generating project files.
Change 3824180 by Ben.Marsh
UGS: Add an option to show changes by build machines, and move the "only show reviewed" option in there too (Options > Show Changes).
#jira
Change 3825777 by Steve.Robb
Fix to return value of StringToBytes.
Change 3825810 by Ben.Marsh
UBT: Reduce length of include paths for MSVC toolchain.
Change 3825822 by Robert.Manuszewski
Optimized PIE lazy pointer fixup. Should be up to 8x faster now.
Change 3826734 by Ben.Marsh
Remove code to disable TextureFormatAndroid on Linux. It seems to be an editor dependency.
Change 3827730 by Steve.Robb
Try to avoid decltype(auto) if it's not supported.
See: https://udn.unrealengine.com/questions/395644/build-417-with-c11-on-linux-ttuple-errors.html
Change 3827745 by Steve.Robb
Initializer list support for TMap.
Change 3827770 by Steve.Robb
GitHub #4399 : Added a CONSTEXPR qualifiers to FVariant::GetType()
#jira UE-53813
Change 3829189 by Ben.Marsh
UBT: Now always writes a minimal log file. By default, just contains the regular console output and any reasons why actions are outdated and needed to be executed. UAT directs child UBT instances to output logs into its own log folder, so that build machines can save them off.
Change 3830444 by Steve.Robb
BuildVersion and ModuleManifest moved to Core, and parsing of these files reimplemented to avoid a JSON library.
This should be revisited when Core has its own JSON library.
Change 3830718 by Ben.Marsh
Fix incorrect group name being returned by FStatNameAndInfo::GetGroupName() for stat groups.
The editor populates the viewport stats list by calling this for every registered stat and stat group (via FLevelViewportCommands::HandleNewStatGroup). The menu entry attempts to show the stat name with STAT_XXX stripped from the start as the menu item label, with the free-form text description as a tooltip.
For stat groups, the it would previously just return the stat group name as "Groups" (due to the raw naming convention of "//Groups//STATGROUP_Foo//..."). Since this didn't match the expected naming convention in FLevelViewportCommands::HandleNewStat (ie. STAT_XXX or STATGROUP_XXX), it would fail to add it.
When the first actual stat belonging to that group is added, it would add a menu entry for the group based on that, but the stat description no longer makes sense as a tooltip for the group. As a result, all the editor tooltips were junk.
#jira UE-53845
Change 3831064 by Ben.Marsh
Fix log file contention when spawning UBT recursively.
Change 3832654 by Ben.Marsh
UGS: Fix error panel not being selected when opened, and weird alignment/color issues on it.
Change 3832680 by Ben.Marsh
UGS: Fix failing to detect workspace if synced to a different stream. Seems to be a regression caused by recent P4D upgrade.
Change 3832695 by Ben.Marsh
UGS: Invert the options in the 'Show Changes' submenu for simplicity.
Change 3833528 by Ben.Marsh
UAT: Script to rewrite source files with public include paths relative to the 'Public' folder. Usage is: RebasePublicIncludePaths -UpdateDir=<Dir> [-Project=<Dir>] [-Write].
Change 3833543 by Ben.Marsh
UBT: Allow targets to opt-out of having public include paths added for every dependent module. This reduces the command line length when building a target, which has recently become a problem with larger games (due to Microsoft's compiler embedding the command line into each object file, with a maximum length of 64kb). All engine modules are compiled with this enabled; games may opt into it by setting bLegacyPublicIncludePaths = false; from their .target.cs, as may individual modules.
Change 3834354 by Robert.Manuszewski
Archetype pointer will now be cached to avoid locking the object tables when acquiring its info. It should also be faster this way regardless of any locks.
#jira UE-52035
Change 3834400 by Robert.Manuszewski
Fixing crash on exit caused by cached archetypes not being cleaned up before static exit cleanup.
#jira UE-52035
Change 3834947 by Steve.Robb
USE_FORMAT_STRING_TYPE_CHECKING removed from FMsg::Logf and FMsg::Logf_Internal.
Change 3835004 by Ben.Marsh
Fix code that relies on dubious behavior of requiring referenced "include path only" modules having their _API macros set to be empty, even if the module is actually implemented in a separate DLL.
Change 3835340 by Ben.Marsh
Fix errors making installed build from directories with spaces in the name.
Change 3835972 by Ben.Marsh
UBT: Improved diagnostic message for targets which don't need a version file.
Change 3836019 by Ben.Marsh
UBT: Fix warnings caused by defining linkage macros for third party libraries.
Change 3836269 by Ben.Marsh
Fix message box larger than the screen height being created when a large number of modules are incompatible on startup.
Change 3836543 by Ben.Marsh
Enable SoundMod plugin on Linux, since it's already supported through the editor.
Change 3836546 by Ben.Marsh
PR #4412: fix type mismatch (Contributed by nakapon)
Change 3836805 by Ben.Marsh
Fix commandlet to compile marketplace plugins.
Change 3836829 by Ben.Marsh
UBT: Fix ability to precompile plugins from installed engine builds.
Change 3837036 by Ben.Marsh
UBT: Write the previous and new contents of intermediate files to the log if they change. Makes it easier to debug unexpected rebuilds.
Change 3837037 by Ben.Marsh
UBT: Fix engine modules having inconsistent definitions depending on whether modules are only referenced for their include paths vs being linked into a binary (due to different _API macro).
Change 3837040 by Ben.Marsh
UBT: Remove code that initializes members in ModuleRules and TargetRules objects before the constructor is run. This is no longer necessary, now that the backwards-compatible default constructors have been removed.
Change 3837247 by Ben.Marsh
UBT: Remove UELinkerFixups module, now that plugins and precompiled modules do not require hacks to force initialization (since they're linked in as object files).
Encryption and signing keys are now set via macros expanded from the IMPLEMENT_PRIMARY_GAME_MODULE macro, via project-specific macros added in the TargetRules constructor.
Change 3837262 by Ben.Marsh
UBT: Set whether a module is an engine module or not via a default value for the rules assembly. All non-program engine and enterprise modules are created with this flag set to true; program targets and modules are now created from a different assembly that sets it to false. This removes hacks from UEBuildModule needed to adjust behavior for different module types based on the directory containing the module.
Also add a bUseBackwardsCompatibleDefaults flag to the TargetRules class, also initialized to a default value from a setting passed to the RulesAssembly constructor. This controls whether modules created for the target should be configured to allow breaking changes to default settings, and is set to false for all engine targets, and true for all project targets.
Change 3837343 by Ben.Marsh
UBT: Remove the OverrideExecutableFileExtension target property. Change the only current use for this (the MayaLiveLinkPlugin target) to use a post build step to copy the file instead.
Change 3837356 by Ben.Marsh
Fix invalid character encodings.
Change 3837727 by Graeme.Thornton
UnrealPak: KeyGenerator: Only generate prime table when required, not all the time
Change 3837823 by Ben.Marsh
UBT: Output warnings and errors when compiling module rules assembly in a way that allows them to be double-clicked in the Visual Studio output window.
Change 3837831 by Graeme.Thornton
UBT: When parsing crypto settings, always load legacy data first, then allow the new system to override it. Provides the same key backwards compatibility that the editor settings class gives

PR #4405: Fix FGarbageCollectionTracer (Contributed by mhutch)
Change 3838451 by Ben.Marsh
UBT: Fix exceptions thrown on a background thread while caching C++ includes not being caught and logged correctly. Now captures exceptions and re-throws on the main thread.
#jira UE-53996
Change 3839519 by Ben.Marsh
UBT: Simplify configuring bPrecompile and bUsePrecompile settings for modules. Each rules assembly can now be configured as installed, which defaults the module rules it creates to use precompiled data.
Change 3843790 by Graeme.Thornton
UnrealPak: Log the size of all encrypted data
Change 3844258 by Ben.Marsh
Fix plugin compile failure when created via new plugin wizard. Passing -plugin on the command line is unnecessary, and is now reserved for packaging external plugins for the marketplace.
Also extend the length of time that the error toast stays visible, and don't delete the plugin on failure.
#jira UE-54157

#jira UE-54123
Change 3845901 by Arciel.Rekman
Linux: fix crash due to lambda lifetime issues (UE-54040).
- The lambda goes out of scope in FBufferVisualizationMenuCommands::CreateVisualizationCommands, crashing the editor if compiled with a recent clang (5.0+).
(Edigrating 3819174 to Dev-Core)
Change 3846439 by Ben.Marsh
Revert CL 3822742 to always call Process.WaitForExit(). The Android target platform module in the editor spawns ADB.EXE, which inherits the editor's stdout/stderr handles and forks itself. Process.WaitForExit() waits for EOF on those pipes, which never occurs because the forked process never terminates.
Proper fix is probably to have the engine explicitly duplicate stdout/stderr handles for new pipes to output process, but too risky before copying up to Main.
Change 3816608 by Ben.Marsh
UBT: Use DirectoryReference objects for all include paths.
Change 3816954 by Ben.Marsh
UBT: Remove bIncludeDependentLibrariesInLibrary option. This is not widely supported by platform toolchains, and is not used anywhere.
Change 3816986 by Ben.Marsh
UBT: Remove UEBuildBinaryConfig; UEBuildBinary objects are now just created directly.
Change 3816991 by Ben.Marsh
UBT: Deprecate PlatformSpecificDynamicallyLoadedModules. We no longer have any special behavior for these modules.
Change 3823090 by Ben.Marsh
UAT: Improve logging for child UAT instances.
- Calling RunUAT now requires an identifier for prefixing into the parent log, which is also used to determine the name of the log folder.
- Stdout is no longer written to its own output file, since it's written to the parent stdout, the parent log file, and the child log file anyway.
- Log folders for child UAT instances are left intact, rather than being copied to the parent folder. The derived names for the copied names were confusing and hard to read.
- Output from UAT is no longer returned as a string. It should not be parsed anyway (but may be huge!). ProcessResult now supports running without capturing output.
Change 3826082 by Ben.Marsh
UBT: Add a check to make sure that all modules that are precompiled are correctly marked to enable it, even if they are part of the build target.
Change 3827025 by Ben.Marsh
UBT: Move the compile output directory into a property on the module, and explicitly pass it to the toolchain when compiling.
Change 3829927 by James.Hopkin
Made HTTP interface const correct
Change 3833533 by Ben.Marsh
Rewrite engine source files to base include paths relative to the "Public" directory. This allows reducing the number of public include paths that have to be added for engine modules.
Change 3835826 by Ben.Marsh
UBT: Precompiled targets now generate a separate manifest for each precompiled module, rather than adding object files to a library. This fixes issues where object files from static libraries would not be linked into a target if a symbol in them was not referenced.
Change 3835969 by Ben.Marsh
UBT: Fix cases where text is being written directly to the console rather than via logging functions.
Change 3837777 by Steve.Robb
Format string type checking added to FOutputDevice::Logf.
Fixes for those.
Change 3838569 by Steve.Robb
Algo moved up a folder.
