UE4 - Added -AllowCommandletRendering to allow running a commandlet to initialize an RHI
- Added some fixes for null pointer dereferences

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)

- 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.

Adding Texture LOD settings to Device Profiles
- this will improve how we currently edit and override lod settings on a per device type bases.
- LOD Settings can now be set in the Device Profile Editor
- Any device profiles with no values set for LOD Settings, will use the default objects.
- These can be found in BaseDeviceProfiles.ini in the /Script/Engine.TextureLODSettings section
- Appropriate defaults set for those groups not listed.
-Other fixes
- - Incorrect with_editor check in HTML5 target platform, changed to with_engine
[CL 2481510 by Terence Burns in Main branch]
- Created audio device manager which manages weak ref handles to audio devices
- Audio device handles are created with WorldContexts and accessed through UWorld objects
- All access to audio devices are now through audio device handles
- There is a main/default audio device for GEngine for use with the Editor and single worldcontext games

Add a "Force compile at startup" option to the Loading/Savings section of the editor preferences, which will cause the editor to always run UBT to build the project at startup. Particularly of interest to small teams that do not submit build products to VCS.

- Fixes UT servers crashing due to OSSMcp trying to late-cancel pending HTTP requests, when the module has already been unloaded.
- Better solution is being discussed within Core.

- This is especially important on OS X OpenGL where these hitches can be equivalent to several frames, so it is enabled by default for this platform.
- The logging of draw calls is turned on/off with r.UseShaderDrawLog and incurs a fixed overhead as all RHI state is tracked & recorded into the shader cache.
- The actual predrawing is turned on/off with r.UseShaderPredraw and requires an existing cache to be useful, the predrawing takes place at frame-end and can be controlled with r.PredrawBatchTime which the time in ms to spend predrawing each frame until complete, or -1 to do it in one go (currently the default).
- The shader cache is now also versioned with the game able to supply a version distinct from the engine, so that old caches may be invalidated if/when required.
- The shader cache is now compatible with OpenGL SM4 & SM5 on Windows & probably Linux too.
- It may not work correctly with desktop ES2 emulation as that is still untested.
- To make it easier to add to other RHIs the API has been made simper to avoid lots of exposed branches.
