CMake: Fix detection of idiff program

OpenGL / Outliner: QUADS are not supported in core

Tests: Fix compilation error with static OpenMP

Fix drawing of planar transfrom manipulators, update matrix code

Alembic import: prevent crash when cancelling import.

It's possible that cancellation occured between the creation of the reader
and the creation of the Blender object, in which case reader->object()
returns a NULL pointer.

Alembic import: prevent double user decrement when cancelling import.

BKE_libblock_free_us() was called on the object data, which decrements
its user count, after which the same function was called on the object,
which decrements the user count of the object data again. This double
decrement was too much.

Cycles: Fix access of NULL pointer as array

Was confusing guarded allocator for some reason.

3D Manipulator: add back protected flags check

This used to be a separate pass

Alembic: synced gather_objects_paths with visit_objects

This was necessary, but was only mentioned at gather_object_paths (which
I didn't see earlier). That's now also fixed.

3D View: manipulator from custom-manipulators branch

Original code from @Severin with changes from @dfelinto & @hypersomniac.

This doesn't cause many functional changes
besides using new transform manipulators.

Submitted as D2604

Replace CGSubSurf direct includes to GL/glew.h

Cleanup: Unused function

Cycles: Fix corrupted mesh render when topology differs at the next frame

Cycles: Change work pool and global size of split CPU for easier debugging

Cycles: Fix indentation

Cycles: Add missing flush

Cycles: Check ray state properly to avoid endless loop

The state mask wasnt applied before comparison giving false results. It
shouldnt really happen that a ray state contains any flags that need to
be masked away, but if it does happen its better to not get stuck.

Alembic: documented use of CacheReader struct

Alembic: just pass NULL when we know mcmd->reader is NULL.

More explicit, easier to read & understand.

Fix building alembic gtest with buildinfo...
