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.

Static analysis fix: warning C6011: Dereferencing NULL pointer 'KeyState'
Change 3001963 on 2016/06/06 by John.Mahoney
Fix for AutomationTool crash when deploying to default PS4 devkit. When a DeviceName is not specified on the command line, the PS4DevKitUtil.exe Detail command will return the details of the default connected device. If the device's filesystem is mapped by name instead of IP, the name should be parsed from the result and used to build the BaseTargetPath.

Change 3005586 on 2016/06/08 by Steve.Robb
jpeg_decoder::stop_decoding made ((no_return)) again, but with an exit() call to ensure that it doesn't cause compile errors in Android builds.

Fix for crash when pasting T3D data from the clipboard into the content browser. Since the content browser is only expecting a list of object paths, it should avoid trying to process pasted T3D altogether.
#jira UE-31459

Splitting up of TTypeTraits into individual traits to avoid erroneous VC compilation errors.

[CL 3012829 by Robert Manuszewski in Main branch]
Added IsValid to check wether the object is valid and bound to a scripting runtime.
Merging CL#2645093 using UE4-To-UE4-LauncherDev
[CL 2645229 by Keli Hlodversson in Main branch]
* Untangle mutual dependencies between objects and constructor order (OPP-3858):
* FWebBrowserWindow no longer keeps a reference to FWebBrowserHandler.
* CefBrowserWindow is created before creating FWebBrowserWindow and passed to its constructor.
* FWebBrowserViewport no longer has a reference back to the viewport widget.
* Cleaned how some platform specific paths were defined during module initialization.
* Sets current thread name (back) to GameThread after initializing CEF (UE-5165)
* Adopted changes from UT (with some modifications):
* Enable on-disk caching and persisting cookies when requested by server.
* Added product name and engine version to user agent request header.
* Ensure UStruct parameters passed by value to FWebJSFunctions are copied when constructing the argument list and not just their address.
*SWebBrowser scripting: Add support for passing TMap<FString, T> to FWebJSFunction objects.
Note: since the struct serializer does not yet support maps, this only works for arguments passed directly to the function object and not UStruct members nor function return values. OPP-3861
* Add support for passing a reference to the JS promise object implicitly created when calling UFunctions to provide for a way to report runtime errors back to it instead of just passing the return value.
* This also allows for implementing async functionality as the promise object can be saved and used after the UFunction has returned.
Merging CL#2633955, CL#2634077, CL#2634226, CL#2635540, CL#2636167, and CL#2636262 using UE4-To-UE4-LauncherDev
