Cycles: Add support for bindless textures. This adds support for CUDA Texture objects (also known as Bindless textures) for Kepler GPUs (Geforce 6xx and above). This is used for all 2D/3D textures, data still uses arrays as before. User benefits: * No more limits of image textures on Kepler. We had 5 float4 and 145 byte4 slots there before, now we have 1024 float4 and 1024 byte4. This can be extended further if we need to (just change the define). * Single channel textures slots (byte and float) are now supported on Kepler as well (1024 slots for each type). ToDo / Issues: * 3D textures don't work yet, at least don't show up during render. I have no idea whats wrong yet. * Dynamically allocate bindless_mapping array? I hope Fermi still works fine, but that should be tested on a Fermi card before pushing to master. Part of my GSoC 2016.
