Cleanup: moar removal of G.main in BKE area...

Merge remote-tracking branch 'origin/blender2.8' into udim

Alembic: made bl_alembic_import_test.py run again

Two tests are still failing, but at least the API changes in 2.8 have been
applied now.

Cleanup/simplify G.main usages.

Using G.main only to get main bled filepath, or built-in fonts, is OK.
So now using the 'valid' G_MAIN macro here instead.

Fix crahs using ndof

Cleanup: Indentation

Particles: Use local RNG

Currently only obvious cases, but is already a progress.

Duplication: Use local RNG

Makes generation safe for threading.

Add utility function to help debugging concurrent usage of global RNG

Checks are disabled by default, but we need to make them enabled by
porting all required areas, or by removing API which uses global RNG.

Depsgraph: Ensure modifiers evaluation doesn't happen on top evaluated mesh

Depsgraph: Don't update derived mesh for particles on render

Render depsgraph is evaluated from scratch, so it should not be needed
to do such a call.

This also prevents modifier stack from being evaluated on top of already
evaluated mesh

Depsgraph: Add debug option to invalidate data tagged for update

See comment for INVALIDATE_ON_FLUSH.

Depsgraph: Set temp object to invalid state as soon as it becomes inaccessible

Depsgraph: Cleanup, wrap private functions to an anonymous namespace

Use proper UI name

GP Branch: Update gpl->actframe in depsgraph callbacks (fixes COW-related issues)

This commit fixes various problems across the codebase
caused by the fact that the gpl->actframe pointers no longer
get updated on redraw, meaning that various editing tools
were not working.

Applying a similar solution to 59a516913e599ce29754d361246a0d8cb92bd314
here: On the exit node for GP data evaluation, we flush the changed
actframe pointers back to main database, so that the main db
is consistent with the displayed time.

Notes:
- For now, we just reuse the BKE_gpencil_eval_geometry() callback,
since it's the only one there and nothing else was happening there.
In future, when we do convert the GP modifier stack evaluation away
from its drawing-engine based approach, we should split this out into
its own function.

- We also do the actframe update in the COW domain here. While it's
not strictly needed for anything right now, this is something that
should really have been happening, so let's do it the proper way now.

- The alternative approach would've been to modify all GP related
context functions to set this whenever they were called. But that
carries performance penalties, and isn't such a nice solution,
as context getters should really not have side-effects.
