Uncovered by a4aa94c41c. Before that, it would actually be a possible `NULL`
pointer dereference.
It would happen if a `UILayout.prop()` was placed with the `full_event` option
set to `True` (or the C equivalent) for a non keymap-item property.
Now this the `full_event` option is ignored then with a warning print.
Multiple related issues:
* `view_zoomdrag_exec()` required `view_zoomdrag_init()` to be called first to
set up data. Can now easily be done in the `_exec()` function as well though.
* Because of that the operators could not be called in an `EXEC_` context (e.g.
`EXEC_REGION_WIN`).
* With "Zoom to Mouse Position" enabled, zooming from a menu or script would
zoom to the mouse position. That should only happen if the operators are
called directly in the editor.
`view_zoomdrag_init()` would perform a number of sanity checks that
`view_zoom_poll()` already executed. The design of operators forsees that
(non-expensive) context sanity checks are done by the `poll()` callbacks, and
the execution callbacks can then just assume that happened. No reason to be
overly pedantic, we don't do that elsewhere either.
Note that this code is from the earliest days of an operator design. So it's
not surprising that it wasn't using the design "properly".
This commit makes the panel expansion set based on the search results
when the active tab in the properties editor changes. The multi-tab
search patch (D8859) actually doesn't handle this because it uses a
different code path.
This feature uncovered a subtle but fairly significant issue with the
implementation of property search (More details in T81113). Basically,
the search needed multiple redraws to properly display the expansion of
panels based on the search results. Because there is no animation of
panel expansion when switching tabs, the problem was exposed only now.
With this commit, hiding of "search only" buttons and panel size
calculation happens in a single final step of the panel layout pass.
The "search only" layout root flag is removed. Instead every button
inside a panel header is in a single "uiButtonGroup" marked with a
specific "in header" flag, an idea which could be generalized in the
future.

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 makes it unecessary to create a button group when the block
is created, giving more flexibility when creating the first group-- for
example, creating the first button group with special parameters.
For a future patch (D9006) we need these groups for longer than just the
the layout process, in order to differentiate buttons in panel headers.
It may also be helpful in the future to have a way to access related
buttons added in the same uiLayout.prop call. With this commit, the
groups are stored in and destructed with the uiBlock.
Now versioning UserDef is run in readfile.c,
as is done for other Blender data.
Previously versioning was mixed with other run-time initialization,
so it needed to be called later by the window manager.
This replaces the blue theme color for subpanel titles with the the same
fade as for parent panels.
The search color doesn't work well for subpanel title colors. And actually,
because there are often buttons with checkboxes in the panel headers, we
don't have to treat this indicator any differently than regular buttons.

Currently there's no way to know if a button is inactive when it doesn't
match the search results, because they use the same 50% gray level.
This isn't a huge problem, but it could lead to confusion. This commit
uses a subtle solution, a 25% opacity when the button is inactive and
also filtered by search.
This requires flipping the meaning of the UI_SEARCH_FILTER_MATCHES
flag in the code, and also adding a widget_alpha_factor utility in
the widget code.

3D Viewport -> Sidebar -> View -> Local Camera is disabled. When you
click on it, box select starts. This behavior isn't intended, and fixing
it is quite simple. The only case where this would continuing would
still be desired is if a disabled button overlapped with a non-disabled
button, but this shouldn't be the case anywhere.

Version patching userpref.blend wasn't using the correct version,
causing settings not to be properly updated.
This seems the likely cause of T70196 and similar bugs.
It looks like this code was left over from tabbed panels in the
properties editor. It wasn't used anywhere except for in one line of
the horizontally-aligned panel code that was recently removed.

The "UI_panel_set_expand_from_list_data" doesn't need to be in the
public API since it's just called every time an instanced panel is added.
This commit just sets the expansion automatically and adjusts some
naming to account for the moved function.
Although I haven't seen this cause any visible errors, there is some
incorrect handling for setting panel expansion during search:
- Properly check if child panel is active first
- Don't stop traversal at headerless panels that could theoretically
have children
In the 3D view sidebar, the active tool settings panel can be pinned to other
categories, and in those other categories it doesn't redraw when the active
tool changes. This commit checks for pinned panels from the "Tool" category
when checking whether to redraw.
Note that the relatively expensive string comparison is only done for
currently visible pinned panels.

Where the if statement was just a check for an error or an unhandled
condition and there are no else statements, the rest of the function
doesn't need to be indented.
Since the search is applied all in one phase, there is no need to store
a reference to the search filter in every uiBlock. Instead just pass it
as an argument to UI_block_apply_search_filter.
Setting the search match flag every time property search runs can
invalidate the results for panel headers. Instead, clear the flag on
every redraw and or the result of every search in the panel to it.
Own mistake in rB9dcae4eb17d7b.
We cannot use ED_object_constraint_active_list in uiTemplateConstraints
since it is dependent on mode (pose vs. object). Now get object
constraints directly when use_bone_constraints is false.
Note: unfortunately a derivate of this bug has made its way into 2.90.1

It's generally considered a better codestyle to check conditions early
and exit early when they are not met, over having most logic of a
function within a big `if`-block. Otherwise people have to go over the
entire block to see if there's possibly an `else` somewhere, or any
followup logic.
There's the old and ugly hack where the `uiBut.poin` points to the
button itself. When reallocating the button we have to update that
pointer of course.
The function this was in already checks the conditions under which it
can operate (as it should). No need to force the caller to do these
(quite specific) checks, the function can just do nothing if the button
doesn't need these operations.
Otherwise we'd have to always execute these checks before calling, which
makes calling it a hassle, makes the code harder to follow and generally
harder to maintain (what if the conditions change?).
The search should check if a panel is active before changing its
expansion, otherwise it sets the expansion for all of the region's
panels, even invisible ones in other tabs.
Checking for the layout alignment is not a reliable way to filter out
which items need the additional icon/text offset. Instead check if the
buttons are icon-only (which we rarely do, e.g. for collection colors in
the Outliner context menu).
For example you can now start entering text in the Properties or
Outliner search, and press the 'x' while the button is still in
text-edit mode.
This way you don't have to exit text editing first, before being able to
quickly clear the string with a mouse click. So this is a small
improvement for convenience.
It also works for the eyedropper (change to picking an object while text
editing) or the '+' and '-' icons in the file saving dialog.
