Internally UV selection considered close UV's to be connected.
While this could be convenient in some cases,
it complicates logic for more advanced selection operations that
need to check when UV's should be considered part of the same vertex
since simple threshold checks would give different results depending
on the order of UV's tested.
Users must now run "Merge by Distance" instead of relying
on this selection threshold.
Instead of using the mouse cursor position,
this selects between existing selected elements.
Access this since picking a selection path doesn't
work from the menu.
This adds support for path selection for vertex edge & face selection
modes, matching mesh editing behavior, useful with the UV rip tool.
Region select & edge tagging are currently not supported,
although they could be added eventually.
New rip tool matching edit-mesh rip functionality.
Useful as disconnecting UV's, especially for loops is inconvenient
without this.
This uses 'V' to rip, changing stitch to 'Alt-V'.
This feature was added when Blender used tex-face (per-face images),
but doesn't make as much sense since this was removed.
Removing this from UV edit-mode as this wasn't working in any
of the 2.8x releases, causing UV's to be visible but unselectable.
Resolves issue raised in T76958.
Seems like this was left out when UV operators were converted to multi-
object-editing, ref T54645.

selections
Previously this was only supported in single click selections, doing an
island selection with box/circle/lasso would just select individual
vertices instead. Now selects islands properly.
This also unifys some logic between box/circle/lasso:
- use early selection test from lasso [makes things faster] in box/
circle
- circle wasnt checking visible face
While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

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.
If pre-deselecting takes place, then flushing was not happening
('changed' never became true because no new faces were being selected).
This rectifies the logic. (also removed redundant double initialization
to false)

Since BM_uv_vert_map_create would return NULL for an empty mesh, code
would then return from uv_select_linked_multi [where it should just skip
and continue instead...]

Caused by rBeead6a604602.
Above commit didnt account for different element types being tagged (face
select mode tagged faces, others tagged loops) and always flushed from
loops.
Now restore to flush from faces if we are in face select mode.

This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.

Fixes T67902: Crash when undo a loop cut

In 2.7x UV sculpt was a kind of sub-mode
(a toggle with it's own key-map & drawing code).
Move this to an operator that uses the tool-system,
this simplifies internal logic, especially brush selection
which now matches sculpt and other paint modes.
- Remove toggle used to enable uv sculpt.
- Expose the brush, which was already used but there was no way to
select different brushes.
- Make UV sculpt use paint paint tool slots
(using brushes how all other paint mode currently do).
- Move UV Sculpt keymap to the tools keymap.
- Remove Q to toggle UV sculpt mode,
S/P/G keys to switch tools.
