- 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.

- CDO property values that have changed after hot-reload will now be propagated to the existing instances
- Adding code to a non-code project will no longer require restarting the editor to be able to work with new code (the new module will automatically be compiled and loaded)
[CL 2385307 by Robert Manuszewski in Main branch]
The auto-startup module list is now compiled to:
1. Exe if the target is a program.
2. Game module binary if the target is game, editor etc.

Note: the changes here are only for Mac - it is likely that similar changes will be needed for other Clang platforms when they get upgraded.

In contrast to the previous system, this does not require special-casing for Rocket builds and will work correctly for nightlies and other out-of-band releases. It also removes the requirement for games to adhere to a strict format of version string on Windows for the editor to be able to load them, since the new data is injected indepdendently of the default resource by UBT.
