Metal implementation for RHIBlockUntilGPUIdle.
Change 2842838 on 2016/01/25 by Mark.Satterthwaite
When using parallel command contexts in Metal we must ensure that the FRingBuffer is still valid, which means some smart/weak pointers are in order. We should also ensure that functions that may return auto-released objects are appropriately wrapped with scoped autorelease pools. Texture creation failures should also be fatal as we never expect that to occur.
Change 2842914 on 2016/01/25 by Mark.Satterthwaite
Change assert in MetalTexture's format-shifting SRV constructor to enforce the Metal textureView limits:
1. No format shifting for MSAA color buffers.
2. No access to stencil in MSAA packed depth/stencil surface.
This will allow Metal MSAA support to work on iOS when using separate depth & stencil textures since there's no format shifting involved there.

Change 2843028 on 2016/01/25 by Mark.Satterthwaite
In Metal wwitch to blit on the correct context when copying out the stencil data into the stencil SRV copy.

2015 compile fixes for Orion
Change 2847395 on 2016/01/28 by Mark.Satterthwaite
Clear the stencil-SRV copy to 0 in Metal using a blit when created to avoid artefacts if used prior to the parent texture being rendered.
#jira UE-25834
Change 2847419 on 2016/01/28 by Mark.Satterthwaite
Apply the same fix to OpenGL's Stencil SRV logic as CL #2847395 applies to Metal.
Change 2848093 on 2016/01/28 by Mark.Satterthwaite
Cache parallel encoding Metal contexts & reuse them rather than creating a new one each time in order to massively improve parallel encoding performance. This required adding a reset function to Metal's internal state-cache which calls the CommandEncoder wrapper's reset so we don't accidently retain previous state.
Change 2849469 on 2016/01/29 by Mark.Satterthwaite
Defer render & compute command encoder construction to draw/dispatch etc to eliminate redundant encoders that then perform unnecessary driver & GPU synchronisation work. Currently Clear loadActions force an encoder even if it would then be empty as otherwise we see incorrect rendering. This needs to be tracked and optimised away too in order to achieve the same performance as D3D11.
Change 2849820 on 2016/01/29 by Daniel.Lamb
Fixed issue where a single DDC back end would not create a hierarchy.
#codereview Peter.Sauerbrei
Change 2850762 on 2016/02/01 by Jeff.Campeau
System-wide critical section support for Xbox One
Change 2850763 on 2016/02/01 by Jeff.Campeau
Network and product config for Orion
Change 2852459 on 2016/02/02 by Mark.Satterthwaite
Temporarily disable the lazy render command-encoder construction while investigating why it turns some samples black in Metal SM5 mode.
Change 2853947 on 2016/02/03 by Mark.Satterthwaite
Fix some lazy encoder construction fallout which also means we don't need to recreate render encoder state when performing profiling - the next draw/clear will do that as required.
Change 2854015 on 2016/02/03 by Mark.Satterthwaite
Move Stencil SRV blitting into FMetalSurface::UpdateSRV called when binding the texture SRV instead of having it done immediately post-rendering. This should avoid paying for the blit when stencil SRV sampling is never used or multiple blits when render-encoders that write stencil are split up due to query buffer overflow or similar. The cost will be a blit per-bind instead which should be more predictable.
Change 2854142 on 2016/02/03 by Mark.Satterthwaite
Implemented GetTextureBaseRHI (brought over from Dev-Rendering CL #2853948) for Metal to avoid unnecessary virtual function call chain to resolve the FMetalSurface* from an RHI texture.
Change 2854222 on 2016/02/03 by Mark.Satterthwaite
Remove the uniform buffer resource caching from Metal to match Dev-Rendering CL #2853948.
Change 2854246 on 2016/02/03 by Mark.Satterthwaite
Removed the uniform buffer resource caching from OpenGLDrv & implemented GetTextureBaseRHI to avoid unnecessary virtual function calls to match Dev-Rendering CL #2853948.
Change 2854279 on 2016/02/03 by Mark.Satterthwaite
Remove direct access to the MTLCommandQueue, for parallel rendering to work we're going to need to do a bit of management that means its more sensible to keep it private.
Change 2855524 on 2016/02/04 by Lee.Clark

UE-23930 Fix for concatenator node's not working correctly when it has child nodes that are mixer nodes.
- Fix was to track the number of sounds a sound a node can simultaneously play. In concatenator node, when a sound is notified as finishing, it tracks the sound index in the current child node before incrementing the child node index.

Make scene queries thread safe by ensuring that any data that is not thread safe is not returned. This is for the benefit of the user, but also we cannot access these pointers off the game thread.

Pass parameters around by const ref instead of value (FGameplayAbilityTargetDataHandle , TArray, FHitResult)
Eliminate unnecessary multiple derferences of weak pointers in a single function
Remove uses of auto, switch to using nullptr
Reorganize booleans to properly pack them
Const functions
Properly mark functions virtual and override

UE-19482 Fixing error in reporting audio asset memory usage for PS4 (and other platforms)
- Issue was that USoundWave::GetResourceSize() was incorrectly summing uncompressed PCM data size alongside compressed data size for PS4
- Added check using same condition in FAudioDevice::Precache which determines if compressed asset is fully decompressed into memory (and other decompression modes/types).
#codereview marc.audy, marcus.wassmer
#tests Tested loading maps in PS4 and confirming the uncompressed PCM data is not counted in audio asset resource size checks. Tested cooking assets in a map.

Fixed duplicate slot names in anim slot groups. This was caused by not building the slot->group mapping at serialize time. COL would then re-add all the used slots to the group for a second time as the mapping wasn't built until postload.

- This is a first pass
- Mac uses data outside the .app so that there's only one copy of the content. This should get a bootstrap executable like Windows has
- Only tested on Mac so far, although it doesn't handle D3D11 shaders, or some of the icon updating for the bootstrap working
- Added Desktop platform icons
[CL 2505866 by Josh Adams in Main branch]
- Added class to hold values (AndroidSDKSettings)
- Added code to Android editor module to setup the values on load
- Changed device detection so that the thread is always started and the SDK path can be changed on the fly
- Changed Platform Target Management Module so that a single platform can be checked via UBT
- Settings can now be sourced from an ini file via temp direct reading code (auto seralisation is disabled until later changes are made)
-- Settings currently not exposed in editor
- Added Mac Environment var setting support
Unreleated
- Envars can now be passed down to process start points in tools
