f2176b3ff3 Shading: Extend Musgrave node to other dimensions.
This patch extends Musgrave noise to operate in 1D, 2D, 3D, and 4D
space. The Color output was also removed because it was identical
to the Fac output.

23564583a4 Shading: Extend Noise node to other dimenstions.
This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D
space. The noise code has also been refactored to be more readable.

The Color output and distortion patterns changed, so this patch
breaks backward compatibility. This is due to the fact that we
now use random offsets as noise seeds, as opposed to swizzling
and constants offsets.

f491c23f1e Cycles: inline more functions on the GPU
This makes little difference for CUDA and OpenCL, but will be helpful
for Optix.

2b999c6a68 Cycles: change svm node decoding for more efficient code generation on GPU
These functions no longer accept NULL. They were renamed for clarity and to
avoid hidden merge issues.

46d8bcb617 Cleanup: Remove unused Noise Basis texture code.
Same as last commit, code is unused and this one actually would have required some fixes,
as these variants output values outside the 0-1 value range, which doesn't fit Cycles shader design.

ae7d84dbc1 Cycles: Use native saturate function for CUDA
This more a workaround for CUDA optimizer which can't optimize clamp(x, 0, 1)
into a single instruction and uses 4 instructions instead.

Original patch by @lockal with own modification:

  Don't make changes outside of the kernel. They don't make any difference
  anyway and term saturate() has a bit different meaning outside of kernel.

This gives around 2% of speedup in Barcelona file, but in more complex shader
setups with lots of math nodes with clamping speedup could be much nicer.

This was already mixed a bit, but the dot belongs there.

c18712e868 Cycles: change __device and similar qualifiers to ccl_device in kernel code.
This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values
are reserved for compilers. I apologize to anyone who has patches or branches
and has to go through the pain of merging this change, it may be easiest to do
these same replacements in your code and then apply/merge the patch.

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

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:
