Fix some review comments (Variable naming and spacing).

Merge branch 'master' into soc-2016-cycles_images

Cleanup: Share as much code as possible in tex_alloc() for both Fermi and Kepler.

Cleanup for Bindless Textures, keep tex2/3D defines in kernel_compat_cuda.h.

Merge branch 'master' into soc-2016-cycles_images

Some further fixes for Bindless, 3D Textures still don't work though.

Merge branch 'master' into soc-2016-cycles_images

Bindless Textures are now usable.

* 2D Textures work fine (float4, byte4, float and byte) types, plus the new limit on Kepler cards is now 1024 per type, so 4096 textures in total.
If we ever need more, this is a one line change.

* 3D Textures (Smoke) do not show up yet, need to investigate this.

* Some cleanup of previous commits, can still deduplicate sume stuff though.

Further work on bindless textures.

Doesnt work properly yet, textures are black.

Add basic code for bindless textures.

This is just the basic declaration, we need to fill these structs properly still.

Cleanup: Have a clear distinction between pre Kepler and Kepler cards in tex_alloc().

This temporarily breaks Image Textures on Kepler, untill Bindless textures are implemented.

Bindless Textures: Some cleanup.

1) Rename extended_images to bindless_textures

2) Remove kepler textures slots, they will no longer be needed.

Nothing to see here yet. Just some preparations for further work.
