Cycles: Fix stack overflow during traversal caused by floating overflow

Would be nice to be able to catch this with assert as well, will see what would
be the best way to do this/.

Need to verify with Mai that this solves crash for her and maybe consider
porting this to 2.79.

Fix T51805: Overlapping volumes renders incorrect on AMD GPU

We need to make sure we can store all volume closures for all objects in volume
stack. This is a bit tricky to detect what would be the "nestness" level of
volumes so for now use maximum possible stack depth. Might cause some slowdown,
but better to give reliable render output than to fail quickly.

Should be safe for 2.79 after extra eyes.

Fix T52218: Missing update when reconnecting node

If node was connected to output, we tag tree for update no matter where
the node was re-plugged to.

Should be safe for 2.79.

Fix T52466: Silence search for button_context menu type.

We were showing "search for unknown menutype WM_MT_button_context" messages in terminal which were not helpful for users, so now they are disabled.

To be backported to 2.79

Fix threading conflict when doing Cycles background render

It is possible to have same image used multiple times at different frames,
which means we can not free it's buffers without any guard. From quick tests
this seems to be doing what it is supposed to.

Need more testing and port this to 2.79.

Fix T52454: Crash in DEG_graph_on_visible_update when activating scene layer

Most likely needs in 2.79 final release.

Fix T52473: blender internal Fresnel and Layer Weight only work with linked normal.

Please backport this to 2.79.

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.
