Ensure that all threads on a multi-core system are used.
The issue was that BLI_task module was trying to be smart and
used heuristic to find optimal number of iterations per thread.
This heuristic assumes that tasks are light-weight, which is
not a case for subdivision surface.
On a higher subdivision level with a file from T70826 the
evaluation time goes down from 0.25 to 0.17 seconds per modifier
evaluation.
When D6189 is finalized we can being some extra performance
improvement.
Usage of spinlock during heavy IO gave reduced performance
see D6267 for details.

This commit adds a new command line argument --debug-ghost and
makes it so X11 errors happening during context initialization
are only printed when this new flag is sued.
There is no need to flood users with errors when their GPU is
not supporting latest OpenGL version. Or, at a very minimum,
the error must be more meaning full.

This only frees brush_rng and random_tex_array when they were actually
previously allocated.
In a unit test (see D6246) I want to be able to partially start Blender
so that I can load a blend file. To prevent memory leaks, I also want to
be able to release memory, which currently requires calling
`BKE_blender_free()`. This unconditionally calls `RE_texture_rng_exit()`
and `BKE_brush_system_exit()`, which now crash on freeing `NULL`. This
patch fixes that.
Allocation (`BKE_brush_system_init()`) and freeing
(`BKE_brush_system_exit()`) are done asymmetrically. The allocation
functions are called from `main()` in the creator module, but the
freeing is done by `BKE_blender_free()` the Window Manager. Ideally we
symmetrise this and initialise Blender from outside the window manager
(so that the initialisation can be done without WM and Python too), but
for now I'm happy when things don't crash.

This patch includes a modifiers that developed for NPR rendering.
- MultiStroke modifier that generates multiple strokes around the original ones.
Differential Revision: https://developer.blender.org/D5795
The root of the issue goes to the discontinuity between the way how
mesh_calc_modifiers() and BKE_sculpt_multires_active() works.
At some point detection of original data usage by a modifier got
broken: the mesh_final based check is unreliable because deform-only
modifiers will create mesh_final for the connectivity information.
This made it so modifier stack evaluation would skip multires
evaluation, but the sculpt code will assume the multires is properly
applied.
This change makes it an explicit check about whether there are any
non-deform-only modifiers applied.
Pair programming and review together with Bastien, thanks!
There was a discontinuity between how deform-only modifiers are applied
for the case when result deform mesh is requested and when it is not.
Namely, the input mesh will always be guaranteed to present in the
former case, but not in the latter.
This change makes it so input mesh to deform-only modifiers is always
at consistent state.

As correctly pointed out by a comment in the code, adding
new springs wasn't thread safe, and caused crashes.
Fix by buffering new springs in intermediate thread-local
arrays, which are flushed on the main thread. This is valid
because the new springs are not used until the next sim step.

Most of the time Stretch To is used in actual rigs, like BlenRig
or Rigify, in combination with Damped Track to handle rotation
before the stretch, because it produces rotations more appropriate
for organic deformation, and doesn't flip because of internal
gimbal lock.
The prevalence of this pattern suggests that Stretch To should
support that kind of rotation directly as an option.

Combine computing `size` and normalizing the matrix, invert the
direction of `vec` to avoid negating it later, use `rescale_m4`

We also need to rebuild the whole collection/viewlayer object cache
thing when we relink an objector collection in a collection (since it
might be part of a view layer).
Again, usual disclaimer about how inneficient this is currently, needs a
serious refactor to only tag caches as dirty, and actually rebuild the
whole thing on access.
This introduces object mode tagging for data which hasn't yet been
written back to the ID data.
Now when selecting other sculpt objects, the original objects data is
flushed back to the ID before writing a memfile undo step.

This implements the shrinkwrap options suggested in D5933. I did a few

The previous default was 1.7, so the brush was more stable on surface
normal changes, but softer. I don't think users expect this brush to be
that stable, so by using 1.55 we make the brush a little bit stronger on
curved surfaces by default.

In 2011 special handling was introduced, apparently for no other
reason than to address a complaint in T25707 that World and Local
space are equivalent for objects without parent. This causes issues
and confusion, as mentioned in rB599c8a2c8e4.
This special meaning of Local Space is not documented in the manual,
and is not known to experienced riggers, so removing it should not
be a problem.
