92774ff792 Cycles: Use explicit qualifier for single-argument constructors 
Almost in all cases we want such constructors to be explicit, there are
exceptions but only in few places.

734d1aec3f Cycles: Make CUDA adaptive feature compile a Debug flag. 
If the CUDA Toolkit is installed and the user is on Linux,
adaptive, feature based CUDA runtime compile is now possible to enable via:

* Environment flag CYCLES_CUDA_ADAPTIVE_COMPILE or
* Debug menu (Debug value 256) in the Cycles UI.

b42878012c Cycles: Make Clang 3.6 happy with const debug flags reference 
For some reason it did not like the explicit const qualifier for a
custom type.

ac7aefd7c2 Cycles: Use special debug panel to fine-tune debug flags 
This panel is only visible when debug_value is set to 256 and has no
affect in other cases. However, if debug value is not set to this
value, environment variables will be used to control which features
are enabled, so there's no visible changes to anyone in fact.

There are some changes needed to prevent devices re-enumeration on
every Cycles session create.

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

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:
http://web.maths.unsw.edu.au/~fkuo/sobol/
* Film response functions from:
