Anim Multithreading: thread-safety refactor
Segregated access to various parts of anim update data by spitting off a new proxy class (FAnimInstanceProxy) containing all data accessed in Update() and Evaluate() passes. Gated access to the proxy data on the game thread in a number of ways:
- Explicit access via GetValueOnGameThread() - this blocks on any existing task, completes and then allows control to return to the accessing function. This allows stuff like Blueprints to continue to operate as normal.
- Explicit access via GetValueOnAnyThread() - this ensures that in the limited set of circumstances we need this (Blueprint pure functions mostly) that conditions are met about concurrent access.
- Deprecating many APIs on UAnimInstance that should not be used (and in fact are not used at present, happily).
Derived classes of UAnimInstance can override the creation of the proxy class to create their own type. We do this for UAnimSingleNodeInstance etc.
Any API deprecation should continue to function - no functions have been removed yet. The only things that are not backwards-compatible are direct access to some public member variables for which there is no way to support (e.g. via references, for example UngroupedActivePlayerArrays).
Some APIs have been changed to more specifically represent the dependencies involved. For example TickAssetPlayerInstance() used to take a UAnimInstance*, only to use it to simply queue notifies. This has been deprecated and replaced with a new FNotifyQueue API. FNotifyQueue also uses a thread-safe FRandomStream instead of FMath::Rand.
Many changes are due to substituting accessor functions for direct variable access.
Removed 'service' tick group as we no longer need to segregate the running of our parallel update.
Anim nodes that need to do some game thread-side update should register for a pre-update callback delegate in the proxy. See FAnimNode_AnimDynamics for an example of this.
Moved UpdateActiveVertexAnims into FAnimRuntime so I can subsume some of the code that was in USkeletalMeshComponent::EvaluateAnimation into UAnimInstance (and hence keep the proxy access private).

Removed potentially troublesome references to BP-constructed UProperties, replacing them with the property FName.

Added guard to prevent multiple initialization to save this more expensive work being done more often.

UE-23091 Adding more logging for NaN checks and fixing one source of NaNs for audio.
OmniDirectional Math Explanation:
For XAudio2, because we do our own distance-attenuation calculations, we use the X3dAudio2 API to simply compute a speaker-map for spatialization and force the listener to be at the origin and the emitter to be on the unit-circle. Thus, from XAudio2's perspective, all distances for every listener-emitter pair will be 1.0.
So in order to use the InnerRadius blending feature, we need to trick it into doing a an inner radius blend relative to a distance of 1.0. For example, if OmniRadius and Distance are the same, then the "NormalizedOmniRadius" is 1.0 and XAudio2 will begin its "blend" of the sound to an omni-directional speaker map.
If Emitter-listener distance is less than the OmniRadius, we'll want to do more blending to an omni-directional speaker map, but we need to set the InnerRadius to something greater than 1.0 (i.e. so that the normalized distance of 1.0 will be treated as less than the InnerRadius). To do "full" omni-directional blending, the emitter-listener distance will be 0 or close to zero, and the NormalizedOmniRadius will be very large (i.e. close to infiinity).
The previous math just set the NormalizedOmniRadius to FLT_MAX which is fine but that number is eventually squared before making the API call. FLT_MAX squared is INF.
Note: I do not think we need to square the OmniRadius in:
Emitter.InnerRadius = OmniRadius*OmniRadius;
But I am keeping it t here because of legacy content which depends on that behavior.

Fix to anim instance proxy to not rely on state machine initialization to bind native delegates as nested state machines are not guaranteed to be initialized. This was fixed in UAnimInstance originally but broken again by the proxy instance code.

crashfix was putting bad bodies to sleep at start
Fatal error!
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000
UE4Editor-Engine.dll!USkeletalMeshComponent::InitArticulated() [...\\engine\\source\\runtime\\engine\\private\\skeletalmeshcomponentphysics.cpp:875]
On some skeletalmeshcomponent, some bodies aren't getting created correctly. Trying to force them to sleep was causing a crash - it expected instantiated physx bodies. Seems that all the rest of the code is able to tolerate bad bodies.
Added check to ensure physx body exists before trying to force it to sleep.
not sure if bad bodies are the norm or if this fix is just more "kicking the can down the road".

- Fixed crash when building a LOD with SubActors.Num < 2
- Force HLOD level slider is now always enabled, however won't show complete image if not all HLODs are build
- LODActor tree view item now scrolls into view if selected in the world
- Set bAllowCullDistanceVolume to false for LODActor's static mesh components by default
- Added 7zip files
- Fixed issue with WinINet complaining about http-request without 'http://' prefix
- Changed % reduced or original triangles display string, now uses float instead of int (for < 1% reductions)
- Override texture sizes and automatic texture bias
- Fixed issue with incorrect material merging, not picking up it required mesh-data during baking. Added extra conditions for rendering with mesh-data.
- Now incorporate static meshes with opague materials into HLOD merging
- Fixed issue with incorrect normals after merging meshes who's owning components had been negatively scaled
- Fixed issue with incorrect texture size being set from MergeActor window (was only changing .X component)
- Fixed issue with material merging when meshes with multiple LODs are merged, right now only merges LOD0's together if we are also merging the materials (otherwise, merge each LOD)
- Added ENUM for texture scaling/resizing type that has to be applied while merging the materials
- Added detail customization class for FMaterialProxySettings

CL# 2698724:
UHT speed improvements:
Code is now generated with tabs, rather than going through a separate Tabify step.
Some expensive temporaries created during iteration and during iteration have been removed.
FFunctionData::FunctionDataMap now uses unique ownership instead of shared ownership.
TCString::Spc (and the new TCString::Tab) now uses a compile-time array instead of one generated at runtime with a static.
TSet::Compact no longer rehashes if no compaction was performed.
TArray assignment no longer reallocs to the same capacity.
[CL 2698780 by Steve Robb in Main branch]
Fixed UHT to detect that a parent class hasn't been parsed before it's child and display a better error message.
