Cleanup: Rename variables and comments

UI: Hack topbar to keep all running while found final design

These changes are only to keep running grease pencil with the last merge.

All these UI elements must be relocated to the right place, but if we don't show them in the UI while we get the final place, the grease pencil is unusable.

Remove Draw at Stroke Location

This option at layer level was only for very limited situations and added complexity not needed.

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.

Fixes after merge

Some parameter list change.

Also disabled some functions that will not be used in annotations. Keep the function as reference to be removed when annotation will be back.

Fix segment fault in weight paint for 2.8 old files

This code would be moved to versioning code after merge, but now it's required to manage files created with previous versions of 2.8 (not 2.7x)
