- ICacheStore::Put() has updated documentation to reflect the requirements of partial records.
- ICacheStore::Get() now takes a FCacheRecordPolicy, which is implicitly constructible from ECachePolicy, and allows setting the policy by payload.
- ICacheStore::GetPayload() is replaced by ICacheStore::GetChunks(), which allows loading parts of payloads.
- ICacheStore::CancelAll() is moved to ICache::CancelAll() because the cache can track requests at the top level and cancel them without exposing cancellation on individual cache stores.
- ECachePolicy::SkipLocalCopy has been removed because it is difficult to reason about.
- ECachePolicy::SkipData flags now have a documented meaning for put requests, to hint that record existence implies payload existence.
- The filesystem and memory cache stores have been updated to support partial records, filtering of payloads, and loading parts of payloads.
- Requesting part of a payload will decompress the entire payload for now, until compressed buffers expose a way to decompress only part.
- Fixed a bug in FTexturePlatformData::AreDerivedMipsAvailable() that caused it to return false for structured cache keys.

Any function that may create a request now has a IRequestOwner& parameter, and uses the Begin and End functions on the owner to manage the lifetime of any requests that it creates, as well as using End to invoke the completion callback for any request which has one.
The new FRequestBarrier may be used to block a group from being considered complete in a scope where more requests may be added to it.

This allows the new cache to be implemented more efficiently using the old cache backends because functionality like the corruption wrapper and key length limiter can be bypassed and the individual backends can store cache records in whatever way is most efficient for them.
The hierarchical backend may request payloads when they are not required due to incomplete tracking of backend state, and GetPayload will never fill other backends due to the inefficiency of the existing backend framework.
The filesystem backend does not cache any state in memory, which makes requests for individual payloads less efficient than if it cached a mapping of cache payload key to raw hash after the first request for a cache key.
The HTTP, S3, and pak file backends are not implemented for the new interface.
The backends do not implement ICacheStore::CancelAll() because the existing backend framework provides WaitForQuiescence to wait for completion of async requests, and the implementation of ICacheStore by those backends works with that mechanism.
The non-leaf backends (hierarchical, async put, etc.) do not update stats from the ICacheStore functions.

This will fix a good bunch of ForceRebuildPlatformData in UTexture2D::UpdateStreamingStatus because of the Boot DDC telling it has some mips cached effectively preventing other cache layers from receiving them.
When the Boot DDC is disabled after the editor boot, all the mips will go into oblivion, and nobody will have them anymore, causing stutters in the game-thread while streaming because a second full rebuild is now required.
Any DDC that plans on disappearing should never be alone in the cache hierarchy and should give other levels the opportunity to properly cache data before its disapperance.

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.
