Fix T52439: Crash after adjusting lenght of hair particles.

Regression from rBfed853ea78221, calling this inside thread worker was
not really good idea anyway, and we already have all the code we need in
pre-threading init function, was just disabled for vertex particles
before.

To be backported to 2.79.

Cleanup: remove space from filenames

Tests: fix incorrect check for hidden dir

Copy-pasted mistake in tests and tools.

Fix error in PointerProperty argument list

Regression in a7b3047

Modify menu from last commit

Also correct tool-tip.

Fix T52434: Restore mesh center of mass calculation

The new method while improved for solid objects
doesn't work for non-manifold meshes, keep both.

Fix bpy library load: invalid function signature

PyAPI: avoid redundant PyLong_AsLong call

Assigning to an RNA array converted from Python to C twice.

Fix T52401: "Export Keying Set" operator generated incorrect ID's for shapekeys

To be backported.

Blender 2.79: Point subodules to updated hash

PyAPI: Fix memory leak w/ empty, allocated enums

Fix T46329: scene_update_{pre,post} doc needs clarification

The documentation for the bpy.app.handlers.scene_update_{pre,post}
handlers states that they're called "on updating the scenes data".
However, they're called even when the data hasn't changed. Of course
such handlers are useful, but the documentation should reflect the
current behaviour.

Fixed Alembic unit test

Commit b6d7cdd3cee9312156e20783248a3b12420b7a53 changed how the mesh data
is deformed, which wasn't taken into account yet in this unit test.

Instead of directly reading the mesh vertices (which aren't animated any
more), we convert the modified mesh to a new one, and inspect those
vertices instead.

Fix T52240: Alembic Not Transferring Materials Per Frame

When a mesh changes its number of vertices during the animation,
Blender rebuilds the DerivedMesh, after which the materials weren't
applied any more (causing the default to the first material slot).

Alembic: Renamed variable assigned_name ? assigned_mat

The variable is a pointer to a Material, not to a name/string.

Fix OSX duplicate path in Python's sys.path

The '..' in the path caused simple comparisons to fail.

Blender 2.79: We are entering RC2 stage

Fix T52255: New Depsgraph - Constraint and Drivers not working together when the driver references itself

Alembic import: fix crash when face color index is out of bounds.

This can happen with Alembic files exported from Maya. I'm unsure as to the
root cause, but at least this fixes the crash itself.

Thanks to @looch for reporting this with a test file. The test file has to
remain confidential, though, so it's on my workstation only.

Forgot to change magicnumber of OIIO built lib in previous commit...
