Cycles: added blurrier texture lookups for indirect diffuse paths

Cycles: Added dPdu/dPdv to area ligths so we can use filtered textures on them

Cycles: Cached textures are now assumed to be linear and converted from sRGB during texture filtering where necessary

Cycles: Crash fix

Cycles: More improvements to texture filtering of light sources

Cycles: Cached textures now support extension and interpolation modes

Merge branch 'master' of git.blender.org:blender into cycles_texture_cache

Cycles: Added NULL pointer check

Merge branch 'master' of git.blender.org:blender into cycles_texture_cache

Cycles: Primary rays in branched path tracing now accumulate volume intersections to allow overlapping volumes to be traversed in one single ray march.

making things build on Linux

Cycles: Added texture differentials to mesh light sampling. Currently based on purely specular reflection, can probably be wider than that.

Cycles: wider ray differential calculation for diffuse components of principled BSDF

Cycles: Added ray differential calculation for AO

Cycles: Let OIIO do the sharing of the texture cache, add wider differentials for velvet BSDF

Cycles: Added dNdu to kernel globals on CPU, using it for more accurate ray differentials in specular and glossy reflection

Cycles: ImageTexture node now has dx/dy inputs for offset texture coordinates, being filled out with a hacky shader node duplication a la bump_dx/bump_dy

Cycles: Widened differentials for diffuse and glossy BSDFs for better texture cache performance

Cycles: Fixed texture cache build in Visual Studio - need to tell OIIO to disable AVX

Cycles: removed ?.? at the end of texture cache help text
