9e4914e055 Cycles: 
* Revert r57203 (len() renaming)
There seems to be a problem with nVidia OpenCL after this and I haven't figured out the real cause yet. 
Better to selectively enable native length() later, after figuring out what's wrong. 

This fixes [#35612].

c5ed6765b9 Cycles / Math functions: 
* Rename some math functions:
len -> length
len_squared -> length_squared
normalize_len -> normalize_length

* This way OpenCL uses its inbuilt length() function, rather than our own. The other two functions have been renamed for consistency. 
* Tested CPU, CUDA and OpenCL compile, should be no functional changes.

fb56dbc2af Cycles: procedural texture nodes reorganization. This will break existing files 
using them, but rather do it now that I have the chance still. Highlights:

* Wood and Marble merged into a single Wave texture
* Clouds + Distorted Noise merged into new Noise node
* Blend renamed to Gradient
* Stucci removed, was mostly useful for old bump
* Noise removed, will come back later, didn't actually work yet
* Depth setting is now Detail socket, which accepts float values
* Scale socket instead of Size socket

df625253ac Cycles: 
* Add max diffuse/glossy/transmission bounces
* Add separate min/max for transparent depth
* Updated/added some presets that use these options
* Add ray visibility options for objects, to hide them from
  camera/diffuse/glossy/transmission/shadow rays
* Is singular ray output for light path node

da376e0237 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:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
