The majority of asset reimport machinery is now held within UAssetImportData and FAssetImportInfo. This change allows us to remove the CachedAssetsBySourceFileName map from FAssetRegistry that was previously added to support auto reimport for 4.7.
The functionality of CachedAssetsBySourceFileName has been wrapped up in FAssetSourceFilenameCache, which sits on top of the asset registry in the editor.
This unification allows us to also consistently store the file timestamps and MD5 hashes of imported files. This subsequently allows auto-reimports to be ignored where a source content file has not actually changed (its MD5 is the same).
This addresses UETOOL-365 - Rework AssetRegistry changes to support auto-reimport

Newly installed versions of the engine will now attempt to copy the project-agnostic config settings from a previous engine installation. This happens by way of a versioned manifest that copies old versions when the manifest does not exist, or is a different version. This code path is benign for non-installed versions of the engine (or FPaths::ShouldSaveToUserDir() is false).
EditorGameAgnosticSettings and EditorUserSettings ini paths have been renamed to EditorSettings and EditorPerProjectUserSettings respectively to better convey their purpose. In general, most settings should be saved in EditorSettings (project-agnostic) so that they apply regardless of which project is open. We have some way to go migrating existing settings for this to be the case, however.
Some previously per-project configuration files are now project-agnostic (such as Editor.ini, EditorKeyBindings.ini, and EditorLayout.ini)
GEditor->Access...Settings and GEditor->Get...Settings have been removed in favor of direct access of the CDO through GetMutableDefault<> and GetDefault<> respectively. Global config ini filenames that are not set up are now neither loaded nor saved on build machines, to handle the problem of indeterminate state more generically.
This addresses UETOOL-270 (Most editor preferences should be project-agnostic)

We also now pop up a warning explaining that this behaviour might be undesirable when running source control, giving the user the option to disable it.

- Linkers are no longer UObjects. Renamed ULinker, ULinkerLoad and ULinkerSave to FLinker, FLinkerLoad, FLinkerSave respectively
- Linkers are now associated with their UPackages
- Linker version is now stored in UPackages
- Async loading is now performed on a separate thread (if platform supports it and only in cooked builds), with the exception of PostLoad which is still done on the game thread
- Added UObject::IsPostLoadThreadSafe() function to determine if PostLoad is thread safe and can be executed on the async loading thread (defaults to false)
- UObject creation is now thread safe and can be performed on any thread
- Move many of the linker/UObject globals into FUObjectThreadContext (TLS)
- GetAsyncLoadPercentage() now takes PostLoad into account
- More async loading stats
- Added AtomicallySetFlags/ClearFlags to UObject
- Made FModuleManager thread safe.
- Added FGCScopeGuard as means of preventing GC from executing from non-game thread
- It's possible to disable async loading thread through ini settings.
- Cancelling async loading will now also trigger GC
- Implemented a basic version of async streaming priorities.

Editor: Add UActorComponent and USceneComponent to the class picker list of parents for Blueprints [UE-8915]
- Removed junk code for localizing the existing ini entries, switching to GetDisplayNameText and short tooltips instead
- Add UActorComponent and USceneComponent to the list (gated by the experimental Blueprintable components flag)
- Optimized the vertical screen usage of SClassPickerDialog for the BP parent picker case, keeping it visible in minspec monitors

Added automatic content monitoring for all mounted content directories
Modifications to source content files that reside inside these folders will now automatically be reimported, if they relate to an asset.
New files will also be automatically imported, and deleted files will prompt the user to delete associated assets.
The feature is currently disabled by default, and enabled in Editor Preferences / Loading and Saving.
Notable features still todo/refine:
* Source files rename currently process as a delete/add
* Slow task dialogs need work. We can hopefully get it running in the background / asynchronously over multiple frames
* Batch operations need work
* Profiling/optimisation
* Various message boxes/dialogs need some refinement
* Asset import factories that are dynamically loaded/unloaded will not be picked up by the import manager. Need to figure out a good way of fixing this.
[CL 2419400 by Ben Marsh in Main branch]
* Multicast delegate Add* calls now return FDelegateHandles, and Remove* calls are now all deprecated, except for a new Remove function which takes a FDelegateHandle.
* New FConsoleManager::RegisterConsoleVariableSink_Handle and UnregisterConsoleVariableSink_Handle functions which work in terms of FConsoleVariableSinkHandle.
* Timer calls which don't take FTimerHandles are deprecated.
* FTicker::AddTicker now returns an FDelegateHandle and is removed by an overloaded Remove function.
* DEFINE_ONLINE_DELEGATE* macros now define _Handle variants of the Add/Remove functions which return/take handles.
* Various other handle-based registration changes.
* Some unity build fixes.
* Some simplification of delegate code.
* Fixes for lots of existing code to use handle-based registration and unregistration.

Added support for basing dlc cooks of releases.
Stopped auto save while cooking in editor.
Removed unneeded package file stamp checks from SaveCookedPackage.
Rewrote Ini version settings checking so that it works from cook in editor.
Fixed up cleaning sandboxes so that it runs each time you start cook by the book (a little slower but more correct).
