This implements a general system to implement drag and drop, subpanels,
and UI animation for the stack UIs in Blender. There are NO functional
changes in this patch, but it makes it relatively trivial to implement
these features for stacks.
The biggest complication to using panels to implement the UI for lists
is that there can be multiple modifiers of the same type. Currently there
is an assumed 1 to 1 relationship between every panel and its type, but
there can be multiple list items of the same type, so we have to break
this relationship. The mapping between panels and their data is stored
with an index in the panel's runtime struct.
To make use the system for a list like modifiers, four components
must be added:
1. A panel type defined and registered for each list data type, with a
known mapping between list data types and panel idnames.
1. A function called by interface code to build the add the panel
layouts with the provided helper functions.
- UI_panel_list_matches_data will check if the panel list needs to
be rebuilt.
- UI_panels_free_instanced will remove the existing list panels
- UI_panel_add_instanced adds a list panel of a given type.
3. An expand flag for the list data and implementations of
get_list_data_expand_flag and set_list_data_expand_flag.
4. For reordering, the panel type's reorder callback. This is called
when the instanced panels are drag-dropped. This requires
implementing a "move to index" operator for the list data.

The reason to have this isn't quite clear, but it looks like a vestige
of the 2.5 transition. Removing this makes dragging panels feel
much more responsive.
Thanks to Julian Eisel @Severin for the original change.

Currently the background of a panel is drawn on top of its subpanels
when it is dragged. The solution is to also "select" the subpanels so they
are drawn on top in UI_panels_draw.

The behavior for subpanels was incorrect, and the ideal behavior isn't even clear.
This disables the "collapse all" ctrl click feature for panels that have parents.

The 10g Intel/Win driver doesn't work well with our emulated
intermediate mode. This patch alters the drawing of the drag widget of
the panels to reduce unneeded drawing.
The previous method would draw 16 boxes per widget. This new way would
cache this drawing in a GPU batch and just move the matrix around.

Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

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.
Both the MS headers and blender headers define the HKEY
which gives all kind of inclusion order issues.
This diff renames all *KEY constants to EVT_*KEY to resolve
this conflict.

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.
Under the special circumstance of double clicking and then opening a
panel with sub-panels again, the parent panel's offset in y-direction
was added twice to the child panels: once inside "get_panel_real_ofsy"
and once within "align_sub_panels".
This introduced a visible glitch.

Panel alignment was only updated when panel size changed. Now we can
also recognize changes in the category tabs offset and tag panels
for alignment updates.
`ARegion.alignment` unfortunately is a mixture of value and bitflag
enumerations. When checking for left/right/top/bottom region alignment,
the flags have to be masked out usually.
Most of the fixed cases here probably didn't cause issues in practice,
but could in fact break at any point when surrounding logic changes.
In fact the assert in #region_visible_rect_calc() failed in an older
file from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949035. This
fixes it.
Currently if a panel becomes empty (draw simply returns), it stays
at the last non-empty height. This seems to be caused by some legacy
checks that may be completely obsolete, but the safest fix is to at
least allow resetting height when the panel is open.
Internally tool settings have been moved to the 3D view.
Added the ability for to draw panels from another space/region
so they can be mirrored in the properties editor.
This makes the properties editor navigation bar less saturated. Internally
the icon theme coloring was refactored a bit to move more towards the button
drawing code.
- Rename ui_but_find_active_in_region -> ui_region_find_active_but
- Remove ui_but_is_active (use ui_region_find_active_but instead)
- Re-order ui_but_* functions take the button as their first arg.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

Does the following changes visible to users:
* Use panels and sub-panels for more structured & logical grouping
* Re-organized options more logically than before (see images in D4148)
* Use flow layout (single column by default).
* New layout uses horizontal margin if there's enough space.
* Change size of Preferences window to suit new layout.
* Move keymap related options from "Input" into own section.
* Own, left-bottom aligned region for Save Preferences button.
* Adjustments of names, tooltips & icons.
* Move buttons from header into the main region (except editor switch).
* Hide Preferences header when opened in temporary window.
* Use full area width for header.
* Don't use slider but regular number widget for UI scale.
* Gray out animation player path option if player isn't "Custom"
Internal changes:
* Rearrange RNA properties to match changed UI structure.
* Introduces new "EXECUTE" region type, see reasoning in D3982.
* Changes to panel layout and AZone code for dynamic panel region.
* Bumps subversion and does versioning for new regions.
RNA changes are documented in the release notes:

Design & implementation mostly done by @billreynish and myself.

Word wrap and alignment layout args only used by UI_fontstyle_draw
were vars in uiFontStyle.
These were written to before drawing, so better pass as an argument.
Pass uiFontStyle & uiWidgetColors as const args.
