* For several preview components (cascade + a couple of animation previews), don't create a separate FXSystem for the preview world. Just use the one created internally by the world
* Several bug fixes and improvements to dynamic feature level switch
* Continued conversion of code that references to global feature level.

- Material editor preview nodes now work when the editor is in es2 mode
- Make editor primitives work in ES2 mode
- Fix slate font rendering in ES2 mode
- Remove ES2 shader de-gamma when in the editor
- Add a new linear sampler type for linear textures
- Various fixes for dynamic feature level switching
- When in an emulated feature level mode, display some text in the level editor viewport saying what feature level we're running
- Removed feature level parameter from USkeletalMesh::GetResourceForRendering. Not used for anything
- ParticleVertexFactoryPool is now creates feature level specific vertex factories.

Last render time for textures can now be exposed via an FLastRenderTimeContainer provided at construction time. Only implemented for texture references. Eventually this can unify last render time for normal textures and texture references.

Moved console variables to their corresponding cpp files where possible.
#ttp 319909 - UE4: RENDERING: Change the ConsoleManager code over to use the new typed TAutoConsoleVariable
[CL 2116537 by Joe Tidmarsh in Main branch]
Add explicit constructor to UStaticMeshComponent, ULandscapeComponent and FModelElement so they can be implmented in cpp file, which includes LightMap/ShadowMap.h
Rename PackedNormal.inl to PackedNormal.h and move rest of declaration, so it can be included independent of RenderUtils.h
Move FMaterialRelevance definition from PrimitiveComponent.h to MaterialInterface.h
Move FExpressionInput/FExpressionOutput/FMaterialInput etc. from MaterialShared.h into new MaterialExpressionIO.h, to avoid Material.h pulling in RHI includes
Other required includes added

Break pieces of SceneManagement.h into their own new headers (SceneTypes.h, SceneView.h, SceneInterface.h, PrimitiveViewRelevance.h, PrimitiveUniformShaderParameters.h, MeshBatch.h, FinalPostProcessSettings.h, BlendableManager.h)
Break StaticParameterSet and static param classes from MaterialShared.h into new StaticParameterSet.h
Move FLight/ShadowMapRef definition from Light/ShadowMap.h into SceneTypes.h, to avoid needing to include them globally
Move FPhysicsVolumeChanged delegate definition to SceneComponent.h, to avoid including Components.h
Also fix some non-unity compile errors in AI module

* Provides mid-range stable AO for dynamic rigid meshes
* Movable sky lights are now supported, and distance field AO is used for shadowing Movable sky lighting from dynamic scenes
* Static meshes are preprocessed into signed distance field volumes at mesh build time when the r.AllowMeshDistanceFieldRepresentations project setting is enabled
* Non-uniform scaling does not work with this method (mirroring is fine), animating through world position offset also causes artifacts as the two representations diverge
* Occlusion is computed along cones to reduce over-shadowing, object distance fields are operated on directly (no hierarchy) to obtain enough resolution to prevent leaking, visibility traces are done with cone stepping to allow better parallelization, and shading is done adaptively in space and time using the surface cache.

There was a bug in setting affinity of a thread that assumed affinity from lookup table with key being a thread name. When names was appended with consecutive numbers (e.g. "RenderingThread 1") the mechanism failed. Refactored this to use special static consts describing affinity override'able by different platforms for different affinity types + possibility of setting affinity per thread.

- New target platforms (LinuxNoEditor for client+server, LinuxClient for client, Linux for editor, LinuxServer for dedicated server - mirroring other platforms).
- Preliminary support for gcc in the toolchain (and some safe fixes in code).
- No more lowercasing when accessing files on Linux, tread carefully.
- Changes needed for native compilation and other minor improvements.

#summary Rename Trunc, Round, Floor, Ceil to TruncToInt, RoundToInt, FloorToInt, CeilToInt. Added *ToFloat versions. Repeated for FGenericPlatformMath and all derived classes for all platforms wherever applicable. Corrected comment in Fractional and added Frac() which does HLSL-style fractional (x - floor(x)). Checked for compilation on all projects (with cooking levels wherever applicable). Didn't change Fractional to Frac, this will be done in second commit.
