Fix T77885: crash rendering grease pencil from compositor with multiple scenes

Fix T79676: Video Sequencer image sequence strip source path breaks when
saving with 'Remap Relative' option

Caused by rBf7386b97571e.

Logic in BKE_bpath_traverse_main calls the callback multiple times [as
often as there are images in the strip].

Prior to above commit, the callback was
'bpath_relative_convert_visit_cb' [this one did not have this problem -
since it returned early if the path was already made relative once]

After rBf7386b97571e though, the 'bpath_relative_rebase_visit_cb' is
used [this one should not be entered multiple times, it would modifiy the
directy again and again].

Luckily, we have a flag (BKE_BPATH_TRAVERSE_SKIP_MULTIFILE) that can be
used to prevent this (this will take care of only calling the callback
once in BKE_bpath_traverse_main for the VSE case)

Could be backported to 2.83 I think.

Fix T79324: Crash when changing View Layer while VR session runs

Proper handling of View Layers for the VR session was never implemented.
Now the View Layer of the VR session follows the window the session was
started in.
Note that if this window is closed, we fallback to another window. This
is done to avoid the overhead it would take to maintain a separate
depsgraph for the VR view. Instead we always share some already visible
View Layer (and hence the depsgraph).

Fix T77847: "Add plane > align" causes crash when certain rigs are in the scene (2.83, fixed in 2.90).

Root of the issue was not fixed in 2.90, only hidden by the fact that we
now re-read much less data during undo's that we used to, when some new
datablock gets added or removed.

This is not an ideal solution (as usual when dealing with data pointers
shared across data-blocks), but it's decent enough. thanks a lot to
@brecht for it!

To be backported to 2.83 too.

Fix T79482: Triangulate quads with 'Beauty' can make zero area faces

Fix crash switching render slots when there is only one slot

Fix T79575: Crash loading nested set-scenes

EEVEE: LightCache: Add warning if the cache cannot be saved

Fix T78529: Blend file corrupted during save caused by high Cubemap Size

This just avoid the corruption. A better fix still need to be finished.

Fix T79246 GPUShader: compile error on AWS Elastic Graphics

Fix T79509 Workbench: Object color mode broken if more than 4096 objects

This was due to the new DRWShadingGroup not being saved and reused for
the next objects.

Workbench: Fix broken id pass

Fix T78884: GPencil weight paint crash when painting over modifier generated points

The weight must be added only to the real points, not to the autogenerated points by modifiers. This affects, not only to subdivide, but to any modifier that generate points.

Fix T46568: UV select-linked failure to de-select

Shift-L was de-selecting all instead of the linked UV's.

Fix usercount not decrementing in `gpencil_stroke_separate_exec`

This is part of T79273 where separating a stroke would result in
multiuser gpencil data for the original object.
Real underlying issue seems to be that gpencil multiuser objects (also
the ones created by Alt+D duplicating) have a problem evaluating
modifiers correctly [this will need further investigation].
Not sure if this is a limitation of D5470?

This patch only corrects the usercount on separating [which already fixes
the scenario reported because singleuser gpencil modifiers work
correctly].

Note: we could have also called `ED_object_add_duplicate` with the
`USER_DUP_GPENCIL` dupflag -- that would have taken care of the usercount
--, but then the whole following logic in `gpencil_stroke_separate_exec`
would need to change from **adding** layers/frames/strokes to
**removing** these.

Fix T79207: Crash converting curve to mesh

Fix T78730: CLOG writes/reads outside allocated memory.

Fix several issues in CLOG code:
* In `clg_str_reserve`, allocated memory may be bigger than requested
one, do not assign the latter back to `cstr->len_alloc`.
* `clg_str_vappendf` was mis-interpreting returned value from
`vsnprintf`, and completely mixing total allocated memory and extra
needed amount of memory to allocate...

Simplified code of `clg_str_vappendf` to only have allocating code
handled in one place, makes things easier to follow too.

Think this should also be beckported to 2.83.

Fix T78537: too much memory usage rendering animation with persistent images

For still images, always return 0 for the current frame number. This ensures
Cycles can detects that the image did not change.

Based on patch by Vincent Blankfield.

Fix T79007: Smooth brushes crasing in dyntopo

The custom smooth functions for bmesh and meshes where removed and
replaced by a generic smooth function using the sculpt API, which needs
to initialize the bmesh indices in order to be used
