One more fix for new OSL libs.

OSX: adaptions needed for renewed osl/oiio/llvm

Fix atomix operations on unofficial 64bit archs

Source Checkers: Include intern/ libs we maintain in spelling checks

CMake: use a list for PLATFORM_LINKLIBS

Cycles: Updates for new OSL 1.5 API.

Differential Revision: https://developer.blender.org/D662

Patch by Sergey and myself.

Buildbot: Never write 'master' branch in packed file names.

Implement option to parent object to undistorted position of 2D track

Fix UI still allowing addition of slots in cycles if material did not
use nodes.

Correction to recent rip-tear

Fix T40925: Scene gravity hard limited

Remove hard limit, but keep soft limit because it might cause some
negative effect on physics stability.

Fixes:

* Crash with image drag'n'drop
* Drag'n drop color to paint 2d canvas not working
* Change "Layers" to "Slots" to appease purists.

Code cleanup: ghost style

Fix T41160: Rendering duplifaces crashed blender (cycles)

Move stencil options to own panel under layer tab.

Fix minor issues from recent commits.

* Clone from layer UI not working
* Get trash color when entering texture painting for the first time

Change to previous commit, allow tweaking name at creation time.

UI cleanup:

New layer in texture painting will now allow entering image parameters,
similar to new image.

Allow renaming images from list in layers panel by double clicking.

Thanks to Sebastian Koenig for the report!

Material could end up with invalid texture paint slots on changing
engine.
