Add queued work priority support to auto delete async tasks and schedule DDC Puts as Low priority
ThreadPool threads are now honoring the names they've been given on creation
Move the I/O only async DDC Get into the DDC ThreadPool with higher priority (Normal) than DCC Puts

Defer backfill up to date check to the async put as it may be expensive in the case of a shared ddc for example
This brings performance in line with working with the shared ddc disabled when the local cache is up to date.
Loading Apollo_Terrain_Edit: ~3m -> ~1m40s - DDC Access ~1m10s -> 4s when using the shared ddc

- Use a GUID rather than machine ID for write tests for programs (ShaderCompilerWorker, UnrealPak) that spin up multiple instances.
- When creating missing files for read-tests check if a failure could have been due to another instance creating that path at the same time.
- Improved some logging of issues to make future diagnosis of issues easier.

E.g.
'-ddc-local-missrate=50' simulates a 50% miss rate of keys on the local backend,
'-ddc-shared-misstypes=AnimSeq' simulates misses for any AnimSeq key. Use + to combine keys. E.g. AnimSeq+Audio
Memory DDC, FileSystemDDC and S3DDC support these options as do the classes that wrap other backends (e.g. AsyncPut).

If a filesystem node is not available not prompt the user and optionally retry incase they need to mount a drive or start VPN
Fiilesystem nodes now perform a speed test using a selection of 'DDC sized' files to determine a classification (local, fast, ok, slow).
Add a new 'ConsiderSlowAt' property to the 'Filesystem' DDC node type. If latency to the node is >= this value then the node will be marked as slow which disables touch'ing and reduces file stats
Interface Changes
- Add the concept of a speed class to nodes
- Add GetName to nodes for better debugging / logging
- WouldCache query that allows caches to opt of of consideration early and avoid async tasks being created.
- Create a new 'FileBackedDerivedDataBackend' class that's the for the memory/boot backend and future classes
- TryToPrefetch interface functions for future use
Behavior Changes
- Moved parameter parsing into FileSysteDerivedDataBackend as things were getting out of hand
- FileSystemDerivedDataBackend now performs a speed test using 'DDC sized' files in separate directories and applies a classification
- Slow locations turn off touching of data on read
- Slow locations always return true for CachedDataProbablyExists. It's faster just to try to read and fail
- If the shared DDC is not available the user is prompted incase they need to mount it.

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.

Fix case where non ClientOnly public objects nested instead ClientOnly objects would cook but fail to load, and add ensure to catch these cases in the future.
If the full outer chain isn't available, it can't be loaded anyway, and this finds issues at cook time instead of load time.
We should generally outlaw non-transient objects with transient outers, it does not do what people expect.
