BLI_tasks: simplify/generalize heuristic computing default chunk size.

That code is simpler and more general (not limited to some specific
values of thread numbers). It still gives similar default chunk size as
what we had before, but handles smoother increase steps, and higher
number of threads, by keeping increasing the chunk size.

No functional change expected from that commit.

GPencil: Fix unreported error using Grab sculpt in empty frame

When the grab brush was used in an empty frame, a new frame was created, but as the depsgraph was no tagged, the evaluated data was wrong and the Grab hash failed.

Fix (unreported) missing viewport update deleting a particle

If children hairs were displayed in particle editmode, these would not
update when a particle was deleted.

Fix T65816: Alembic export of procedural mesh results in a static mesh and crashes

The static mesh issue described in T65816 has been resolved by @Sergey
in T60094.

This commit fixes the last bit of the puzzle, which was two-fold:
- A missing depsgraph update when setting `orig_object.data = new_mesh`
from Python. Thanks @Sergey for providing the fix :)
- Properly locking the interface while exporting. This prevents crashes
as described in T60094. The previous approach of calling
`BKE_spacedata_draw_locks()` was not enough.

Fix preference for file browser and new window not being saved

The subversion should just be bumped for cases like this, it doesn't cost
anything and functioning correctly is most important.

Revert "UI: Open file browser in fullscreen by default"

This reverts commit b962aca8003de89683c87c4da348579f756b75cd. We may revert
to the fullscreen file browser if it's not good enough by the time of the 2.81
release. But then it first needs some changes since the in between state now
is not good enough either.

Sculpt: Split original normal into original normal and plane

This allows to create different effects with some brushes that use the sculpt plane.

UI: Open file browser in fullscreen by default

Fullscreen as in, maximized area.

This may be a temporary change until we consider the temporary window
mode as working well enough.
Note that you can still enable the windowed mode in the Preferences
(Interface > Editors > Temporary Windows).

UI: Preference for file browser as fullscreen area

Addes a Preference setting to choose between opening new file browsers
in a maximized area (like with the old file browser) or in a new window
(like the new one).

UI: Move render display type to Preferences

Moves the render display type (to choose between rendering in a new
window, in a fullscreen area, in an Image Editor, etc) from the scene to
the preferences.

Refactor temp-space opening for optional fullscreen mode

Will be put to use in followup commits.

Cleanup: minor changes to paint undo

Use a shared tile freeing function.

Fix segfault when polling OBJECT_OT_voxel_remesh without active object

The active object can be `NULL`, which causes a segfault in
`BKE_object_is_in_editmode(NULL)` (and if that were made NULL-safe, the
segfault would happen further down in `object_remesh_poll()`).

Cleanup: includes for readfile.c

Fix T69989: Correct Mapping node min/max versioning.

The old min/max options specified the target min/max values, they didn't
act as min/max operators. So the versioning code should be adjusted
accordingly.

These asserts are too simple and triggers false positive.

Fix T69809, T69810: sculpt gone or crashing after render

Make a distinction between flush sculpt changes for rendering, and forcing
sculpt data structures to be rebuilt after mesh changes. Also don't use PBVH
for renders.
