OpenGL: software renderer for old Mac GPUs

We raised the minimum to GL 2.1 in Blender 2.77, and dropped support for older GPUs (pre-2012 Intel mostly). On Windows you get a popup message, but on Mac we simply crashed. Every Mac has a builtin software renderer for GL 2.1 so let's use that when the GPU is not capable!

Run blender --debug-gpu to see version detection & software fallback.

adapted manta liquid script to support obstacles

UI Messages: Consistent spelling of term "data-block"

Was using a bunch of different spellings, mostly "data-block" though, so went with that one (would have been my #1 choice anyway ;) )

Buildbot: Another attempt to have OSX builder fixed

Buildbot: Temporary disable CUBIN compilation

Buildbot: Attempt to use proper Clang for CUDA binaries

Cycles: Cleanup code style in split kernel

Fix T49375: align rotation with snap target isn't toggleable in edit mode.

Based on D2237, but fixed patch always hiding 'snap on self' button...

Should be safe for 2.78.

Cycles: More tweaks to make specialized BVH traversal matching

Cycles: Avoid redundant intersection pre-calculation

Cycles: Cleanup, sync some comments across different traversal

Cycles: Cleanup, always use parenthesis

Makes it simpler to compare different traversal algorithms.

Lowercase includes for psapi.h and dbghelp.h windows includes.
This makes cross compilation a little less painful

Fix T49385: Copy buffer is not from pose mode. Report Error

Quick fix for now, need to unlock studio here as well.

Proper fix would be to modify API a bit and pass flags which will
prevent expand called on bmain perhaps. But this we should discuss
a bit,

Cycles: Move BVH constants to an own files, so they are easily re-usable

Remove null-check of argument which is attributed as non-null

This was logically incorrect and was causing warning and compilation
errors with strict compiler flags.

CacheFile: make sure SpinLock is destroyed when exiting Blender.

Missed in rB62b1cdd6.

Cycles: Fix typo that would sometimes result in subsurf modifier being disabled
