If keyboard-layout-per-toplevel-window is used, reset the group (index)
for each window on --reconfigure whenever the keymap has changed.
Refactor to use a common configure function for reconfigure and
keyboard-group creation.

Fixes#1407
Add the -m|--merge-config command line option to iterate backwards over
XDG Base Dir paths and read config/theme files multiple times.
For example if both ~/.config/labwc/rc.xml and /etc/xdg/labwc/rc.xml
exist, the latter will be read first and then the former (if
--merge-config is enabled).
When $XDG_CONFIG_HOME is defined, make it replace (not augment)
$HOME/.config. Similarly, make $XDG_CONFIG_DIRS replace /etc/xdg when
defined.
XDG Base Dir Spec does not specify whether or not an application (or a
compositor!) should (a) define that only the file under the most important
base directory should be used, or (b) define rules for merging the
information from the different files.

In the case of labwc there is a use-case for both positions, just to be
clear, the default behaviour, described by position (a) above, does NOT
change.
This change affects the following config/theme files:
- rc.xml
- menu.xml
- autostart
- environment
- themerc
- themerc-override
- Theme buttons, for example max.xbm
Instead of caching global config/theme directories, create lists of paths
(e.g. '/home/foo/.config/labwc/rc.xml', '/etc/xdg/labwc/rc.xml', etc).
This creates more common parsing logic and just reversing the direction
of iteration and breaks early if config-merge is not wanted.
Enable better fallback for themes. For example if a particular theme does
not exist in $HOME/.local/share/themes, it will be searched for in
~/.themes/ and so on. This also applies to theme buttons which now
fallback on an individual basis.
Avoid using stat() in most situations and just go straight to fopen().

This builds on the work of @Consolatis in #1018.

Whenever the output layout changes, each view's original geometry will
be captured as last_layout_geometry (if it has not already been captured
by a previous layout change), which will remain valid unless the user
modifies the view's geometry (i.e., by tiling, maximizing, moving,
resizing or full-screening). On subsequent output layout changes, views
with valid last_layout_geometry will be back to their original position
if possible, or else to the closest possible output.
The view_adjust_floating_geometry function is called when un-maximizing
a window or changing the output layout to ensure that views are well
placed. Rather than always centering these views should they fall
offscren, use the automatic placement strategy if so configured.
It is nice to have finer granularity for device types to allow for
configurations such as using `naturalScroll` on touchpads, but not on
regular pointer devices such as mice.
Support showing full application
identifier or the trimmed variant in window switcher OSD.
Regression notice: For anyone using ‘identifier’ in window-switcher field configuration, change it to ‘trimmed_identifier’.
Some themes don't have hover variants for button pixmaps.
It looks better visually to use the non-hover variants as fallbacks
rather than the built-in 6x6 pixmaps.
Account for space taken up by XWayland panels (as indicated by the
_NET_WM_STRUT_PARTIAL property) in the usable_area calculation.
This makes it possible to use labwc in a "transitional" setup, where it
replaces the X11 window manager and compositor, but most other parts of
a existing X11 desktop environment can still be used via XWayland.
(Some remaining drawbacks of such a setup would be the lack of desktop
icons, and native Wayland clients not showing up in X11-based taskbars.)
XWayland clients use the _NET_WORKAREA root window property to determine
how much of the screen is not covered by panels/docks. The property is
used for example by Qt to determine areas of the screen that popup menus
should not overlap (see QScreen::availableVirtualGeometry).
Depends on wlroots MR:

v2: prevent calling wlr_xwayland_set_workareas() too early

backend/wayland: use request_state when toplevel is resized

backend/x11: use request_state when window is resized
Ref: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/2693
We now delay requested resolution changes by the backend until
the next frame event which causes us to render the new content
on the already enlarged buffer. Before this change, an empty
(black) buffer would have been shown instead before the next
frame event caused a new render of the actual contents.
Keep commiting the new state and then scheduling a frame event
would not help as due to the commit call it would still show an
empty buffer in the meantime.
Just modifying wlr_output->pending wouldn't work either because
wlr_scene_output_commit() *completely* ignores it (and it will
be removed in future wlroots commits). For this reason we move
to wlr_scene_output_build_state() directly because it allows us
to supply the current wlr_output->pending state and thus apply
any resolution change in lockstep with new rendering. Result:
No more flickering in the wayland backend and resizing is again
smooth as butter.
This prevents constant flicker while resizing
when running nested via the wayland backend.
For the X11 backend (can be tested via `WLR_BACKENDS=x11 labwc`),
it is still rather janky but at least doesn't cause endless self-
resizing anymore.
