Revert "Use one context per OSL thread. Not sure if this actually works, but the simple renderer example in OSL does it this way."
...
This does not actually work: The context must not be shared between threads, but using the same context between different samples actually seems to prevent OSL from switching between shaders. The proper solution would be to ensure memory pooling works correctly.
This reverts commit 69f87e69258d6266dcb20f09f7e3d4021e663432.

Fix for Cycles OSL: The RenderServices pointer in ShadingSystem is no longer accessible from the interface class (presumably because it is just the base class pointer anyway and would have to be casted). The OSLRenderServices pointer to our own implementation is now stored alongside the ShadingSystem in the kernel globals, so it can be accessed in thread_init.

Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later.

Cycles uses code from some great open source projects, many thanks them:
* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:

* Sobol direction vectors from:
