Fix for OSL input parameter name mapping. When assigning input constants to shader parameters, use the compatible_name function to strip whitespace.

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.

The shader id generated by the manager contains some special flags in high bits, leading to out-of-range index if used directly. This must use the SHADER_MASK to get actual array index.

Cycles: revert commit that joined surface/volume socket into a single shader socket,
...
on second thought this makes it a bit too difficult to understand what's going on.

Cycles: replace surface/volume sockets in output nodes with a single shader socket,
...
decided it's better to render objects as either surface or volume.
This may break the volume rendering patch, but shaders with volume closures still
get tagged as having volume closures, so it should be fixable without too many
changes.

Cycles: internal changes that should have no effect on user level yet, added
...
shader flags for various purposes, and some code for light types other than
points.

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:
