Cleanup: Remove legacy depsgraph private header from modifiers

Cleanup, remove unused function

Merge branch 'master' into blender2.8

Depsghraph: Remove unused function

Merge branch 'master' into id_override_static

Fix building on gcc.

Renamed create_rotation_matrix to create_swapped_rotation_matrix and more:

Also replaced the bool param "to_yup" with "AbcAxisSwapMode mode", so that
it's more explicit that axes are swapped.

Also added unittests for create_swapped_rotation_matrix.

Paint cursor changes, so it save/load only the required flags

Immediate Mode: replacing glPushAttrib/glPopAttrib

Reference document: http://docs.gl/gl3/glPushAttrib

This patch only tackles the bits that are set by Blender with the
following exceptions:

1) Deprecated states (e.g., GL_STIPPLE) are not saved/restored

2) The exception being GL_ALPHA_TEST, which will be removed, but it may
affect drawing too much now. To be removed once we no longer set GL_ALPHA_TEST
elsewhere.

3) paint_cursor will be tackled separated, since it was abusing
glPush/PopAttrib in the first place.

4) Despite what the glPushAttrib page above may suggest, GL_DEPTH_WRITEMASK needs glGet, not glIsEnabled

5) BGE is still a problem since it relies on GL_ALL_ATTRIB_BITS which
would lead to a way more complete/lenghty solution. Since the BGE has
other (OpenGL deprecated) problems anyways, it can be handled on its own
time.

Finally, the original design for 2.8 was to implement a proper stack
system. However we need to move to core profile sooner than later. So
this is a pragmatic temporary (that may be permanent) solution.

Differential Revision: https://developer.blender.org/D2600

Viewport: 3D cameras don't need glPushAttrib/glPopAttrib

CMake: Fixed order of bf_alembic in SETUP_BLENDER_SORTED_LIBS

bf_alembic depends on bf_bmesh, and should therefore be above it.

Cycles: Fix race condition in attributes creation during SVM compilation

Cycles: Add utility class to simplify scoped spin locks

Cycles: Guard global write access in SVM compilation code

save and load obstacle velocities (for standalone mode)

Merge branch 'master' into soc-2016-pbvh-painting

added union in sculpt session for modes. Sculpt fields could use some tidying, but that might be outside the scope of this branch. Swapped out some free patterns with MEM_SAFE_FREE. Swapped a long out for an int, since there's no size difference.

Remove USE_IMM ifdefs

Depsgraph: Remove all layer bit flags related checks

These bits became obsolete with the new layer system, so we can
simplify some code around them or avoid existing workarounds which
were trying to keep things working for them.

There are still work needed to be done for on_visible_change to
avoid unnecessary updates, but that can also happen later.

Finish of removal of GLU deps

Will commit full removal next
