Alembic: removed unnecessary matrix copy

Alembic: simplified AbcEmptyReader::readObjectData

Alembic: added some r_ prefixes for return parameters

Add some basic UI and RNA feedback for overriden properties.

For now chose some teal blue to mark overridden state of prop in UI,
kind of last nicely different tint available...

Fixup for layer rename unittest (rB3baa186724)

Layers unittest: isolate the depsgraph crash in individual tests

(and re-order the tests alphabetically)

Gawain: allow use of final 2 bits of 10_10_10_2 format

Requested by @fclem

Edit Mode overlay: Moved Shaders to draw modules and resolved some draw issue.

We don't want to clutter gpu_shader.c with engine specific code
Added face's center dot
Simplified loose vert shader

Edit Mode overlay: Added theme color via UBO.

Edit Mode overlay: fast navigate

Edit Mode overlays: separate multiple shaders for loose edges and verts

Fix T50830: Wrong context when calling surfacedeform_bind

The custom poll function for surfacedeform_bind seems to have caused
issues when calling it from Python. Fixed by using the generic modifier
poll function, and setting the button to be active or not in the
Python UI code instead. (there might be a better way, but for now this
works fine)

Add tests for layer renaming

Could have an own file for each test, but this is good enough.
With great help from @dfelinto, thanks!

Fix collection renaming not checking for unique name in entire hierarchy

Only checked for unique name in direct children of the master
collection.

Also added missing listener for outliner.

Correct comment

Thanks to @dingto for noticing.

Cleanup: Use .enabled instead of .active

Fix T50565: Planar constraints don't work properly with non-Blender key configurations

The issue was introduced by 4df75e5 and seems we just need to explicitly
add new keymap item now.

There is still some difference from old behavior, which is planar transform
is using precision movement since e138cde and here i don't see nice solution
currently: the change was requested here in the studio and it's just a
conflict in picking shift key for something which is not supposed to be
accurate.

At least now it's possible to invoke planar constraint and simply unhold
shift.

Task scheduler: Remove query for the pool's number of threads

Not really happy of per-pool threads limit, need to find better
approach to that. But at least it's possible to get rid of half
of the nastyness here by removing getter which was only used in
an assert statement.

That piece of code was already well-tested and this code becomes
obsolete in the new depsgraph and does no longer exists in blender
2.8 branch.

FIXUP reinstated GHash *

All drop-down buttons should use the same width
