Undo/redo was crashing & asserting.
There ware two bugs:
- Entering particle system edit-mode requires an evaluated depsgraph.
- The active object could get out of sync when undo/redo
moves between different modes.
The new test 'view3d_mesh_particle_edit_mode_simple'
in `tests/ui_simulate/test_undo.py` exposes both issues.
In two cases the percentage property was actually used incorrectly, as
pointed out in T82070. The range was [0, 1], but the properties were still
displayed as percentages.
There is a preference to control whether to display factors or
percentages, so it usually doesn't make sense to manually define
properties as percentages.

The hair mirroring code seems to expect that hair is emitted from faces.
The PE_mirror_x contains the following expression: mirrorfaces[pa->num * 2].
This only makes sense when pa->num is a face index.
The simplest short term solution is to disable the mirror operator when
the particles haven't been emitted from faces.

The issue was that the same point cache was read by multiple
threads at the same time (the same object was evaluated for
render and for the viewport).
Both threads incremented PTCacheMem->cur which lead to the crash.
The fix is to remove the PTCacheMem->cur and store it on the
stack instead. This way every thread has its own cur.

We have our own assert implementation, `BLI_assert()` that is prefered over the
C standard library one. Its output is more consistent across compilers and
makes termination on assert failure optional (through `WITH_ASSERT_ABORT`).
In many places we'd include the C library header without ever accessing it.
This adds XYZ symmetry as a property of meshes and updates all modes to
use the mesh symmetry by default to have a consistent tool behavior
between all modes and when switching objects.

situations
In the situation that the PTCacheEdit is not available (e.g. when
editing unbaked Cloth or Softbody caches - or, as in the report, being
in Cloth or Softbody Editing Type for Hair particles), accesing the
corresponding ParticleSystem or ParticleSystemModifierData would crash.
Now access these later (after PE_start_edit had the chance to return
early on this non-valid situation).

Remove redundantly nested `#if` and `#ifdef` statements.
One nested `#if 0` block was left untouched, as it's in particle code
that's no longer maintained. Furthermore, that block also has some
explanation as to the differences between the enabled & disabled parts.
One nested `#if 0` construct was completely removed, leaving only the
actually used bit of code. There was no explanation as to the usefulness
of the disabled code, and it hasn't been touched in years.
No functional changes.
The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
This caused an additional argument when exiting object modes
and many other low level functions which don't need to access context.
This simplifies fixing T77073.
This patch enables TBB as the default task scheduler. TBB stands for Threading Building Blocks and is developed by Intel. The library contains several threading patters. This patch maps blenders BLI_task_* function to their counterpart. After this patch we can add more patterns. A promising one is TBB:graph that can be used for depsgraph, draw manager and compositor.
Performance changes depends on the actual hardware. It was tested on different hardwares from laptops to workstations and we didn't detected any downgrade of the performance.

In preparation of TBB we need to split the finalize function into reduce
and free. Reduce is used to combine results and free for freeing any
allocated memory.
The reduce function is called to join user data chunk into another, to reduce the
result to the original userdata_chunk memory. These functions should have no side
effects so that they can be run on any thread.
The free functions should free data created during execution (TaskParallelRangeFunc).

Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
This is in preparation of new object types. This only changes mesh_eval, we
may do the same for mesh_deform_eval and other areas in the future if there is

The current "Select Linked" operator works based on mouse position and
makes no sense to call from the menus and was removed in rBdd9dfadaac9b.
This patch adds an operator independent from mouse position that just
selects all keys to a corresponding point (and adds back menu entries,
adds keymap entry).
The original operator is renamed to 'select_linked_pick' internally
(this is now more in line to how "Select Linked" works for meshes,
curves etc)

Selection and grooming only ever happens on hair keys (vertices), so
makes sense to use that theme color.
