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.

Change 3046088 on 2016/07/12 by Ben.Woodhouse
Live GPU stats
A non-hierarchical realtime high level GPU profiler with support for cumulative stat recording.
Stats are added with SCOPED_GPU_STAT macros, e.g. SCOPED_GPU_STAT(RHICmdList, Stat_GPU_Distortion)
The bulk of the files in this change are simply instrumentation for the renderer. The core changes are in SceneUtils.cpp/h and D3D11Query.cpp (this is the XB1/DX11X implementation of timestamp RHI queries, which was missing)
Note: this is currently disabled by default. Enable with the cvar r.gpustatsenabled
Tested on PC, XB1, PS4

UE-23925
Clamping noise tessellation for beams at a high but sensible value; also making sure during beam index buffer building that we never get over 2^16 indices; this is a bit hokey, but there are so many variables that can influence triangle/index count, that this is the only way to be sure (short of nuking the entire site from orbit).

BuildGraph: Allow specifying optional dependencies for a node, indicating that the build products from an upstream node are desired, but should not block the node from running.
Change 2972295 on 2016/05/10 by Ben.Marsh
EC: Remove spacing in notification emails to reduce size, and help prevent gmail from truncating messages. Also allow mailing notification emails when doing a dry run, and reading stream settings from another branch.

EC: Age out entries from the "latest builds" list after a week. There's no obvious way to tell if a node has been removed, but a periodic cleanup should keep the build notifications list in check.

[CL 2982178 by Ben Marsh in Main branch]
Please note that file comments had no purpose in nearly all cases and just added visual clutter. The two files that had meaningful file comments had their comments moved into the corresponding classes. There are still hundreds of file comments left in other files that will be removed over time.
Also cleaned up some random stuff along the way:
- relative paths to public headers within the same module are no longer necessary (automatically discovered by UBT now)
- header guards are deprecated, use #pragma once instead (all compilers support it now)
- space between multiple template brackets is no longer required (all compilers support >> now)
- NULL to nullptr, OVERRIDE to override
- spelling errors, whitespace, line breaks
