Cycles microdisplacement: perform subdivision dicing in raster space

NOTE: this is only the first of many patches towards completing the subdivison
and displacement system in Cycles. These patches will be reviewed and committed
one by one over the coming weeks.

Cycles: Cleanup, make some comments easier to read on split editors

Cycles: Remove hair support from volume BVH traversal

There are couple of reasons:

- Volume shader on hair does behave really weird anyway and it's
not something considered a bug really.

- Volume BVH traversal were only used by camera-in-volume check,
which doesn't really make sense to take hair into account since
it'll be rendered wrong anyway.

Such a removal makes both code easier to extend further (as in,
no need to worry about those traversal for hair bvh) and also
reduces stress on GPU compilers.

Cycles: Remove unused SAH from BVH pack

Cycles: Rename tri_woop to tri_storage

It's no longer a pre-computed data and just a storage of triangle
coordinates which are faster to access to.

Fix T48084: Solidify uses alternate quad-direction

This prevents twisted quads from self-intersecting.

This change makes the duplicate surface match the first vertex in the face,
so the diagonal indices match in the face copy.

Fix T48082: Unwrap overwrites face selection

Sync selection option made adding a new UV layer select all edit-mesh faces.
Now just select the UV's, ignoring sync-select option.

BGE: Fix T48071: Global logic manager

Previously the logic manager was used as a global variable for SCA_ILogicBrick::m_sCurrentLogicManager,
this request to always update it before run any python script and allow call function like
ConvertPythonTo[GameObject/Mesh]. The bug showed in T48071 is that as exepted the global
m_sCurrentLogicManager is not updated with the proper scene logic manager.
Instead of trying to fix it by updating the logic manager everywhere and wait next bug report to add
a similar line. The following patch propose a different way:
- Every logic brick now contain its logic manager to SCA_ILogicBrick::m_logicManager, this value is
set and get by SCA_ILogicBrick::[Set/Get]LogicManager, It's initialized from blender conversion and
scene merging.
- Function ConvertPythonTo[GameObject/mesh] now take as first argument the logic manager to find name
coresponding object or mesh. Only ConvertPythonToCamera doesn't do that because it uses the
KX_Scene::FindCamera function.

Cycles: Fix rare dead-locks on TaskScheduler::exit()

When the Moon is full it was possible to have a dead-lock in task
scheduler's exit() method.

Similar problem was fixed in Blender's task scheduler 3 years ago
in bae2a2c.

Docs: comment on line-sphere intersection

Cleanup a bit particle distribution code.

Also do proper intial/final checks to avoid adding particle on zero-weight extreme items,
instead of using cheap tricks like 'small offset'...

Fix T47983, Take II: Particles - Emit from Verts emits double on one vert.

Previous fix made another issue even more visible, leading to +1 particle on first vert
and none on last one. This commit should fix both original and new issues.

Fix T48078: incorrect OS X command for retrieving number of CPUs on in Makefile.

Fix T48088: Reproducible crash: Edges + Array Mod + Hair Particles.
