Removing a stylesheet from the theme will trigger a style update. There's
little point in updating the extension actors that are about to be destroyed
(hopefully), so call the extension's disable() function first.

Sometimes an MPRIS media player will create and then destroy an object
before the signals that handle the object's destruction can be created.
This verifies that the object still exists after the necessary signals
have been created.

Since commit 0ecddafc20 gsd-xsettings startup has been made conditional
on the systemd user instance being available at runtime. While that is
correct, it means that completing xwayland startup is also conditional
now.
We always want xwayland startup to go ahead, so wait for the XSettings
plugin to appear on the bus when gsd-xsettings is launched by gnome-session
and complete the task immediately if startup fails.

Changing the icon to 'system-log-out-symbolic' has no visual
change in a default GNOME setup since both 'system-log-out-symbolic'
and 'application-exit-symbolic' are the same in adwaita-icon-theme
(at the time of writing), however, other icon themes differentiate
between the two icons so pointing to the appropriate icon name
is the right thing to do.

Avoid starting/stopping the gsd-xsettings systemd unit if the shell itself
was not started via systemd. In the lack of a user session manager, we
have no means to neatly start/stop services, so should rely on the good
ol' gnome-session to do this for us.
This changes the return value meaning slightly, TRUE means "service did
start", FALSE otherwise. The error is only raised if we ought to start,
but it produced an error somehow.

Commit 764527c8c9 not only ports this file
to Promises but also changes the behavior of _initPanelService method.
Instead of always calling _updateReadiness when _panelService is ready,
it only calls it when get_global_engine_async succeeds.
The only callers of _updateReadiness are _initEngines and
_initPanelService. Assume that _initEngines completes first. Its
_updateReadiness call keeps _ready as false and it is expected for
_initPanelService to change it to true. However, since
get_global_engine_async fails because there is no active engine,
_initPanelService never calls _updateReadiness. Therefore, all setEngine
calls do nothing because _ready is false, and the input method panel
never shows. Users are unable to use any input method even if they can
see that ibus-daemon is already running.
Fix the issue by changing it back to the old behavior.

Since we now remove all theme nodes on a stylesheet change (ie.
StTheme's "custom-stylesheets-changed" signal) instead of only
invalidating them, those nodes may not be accessed anymore as soon as
"custom-stylesheets-changed" is emitted.
It turned out though that when comparing them to the newly generated
nodes in `st_widget_recompute_style()` using the
`st_theme_node_paint/geometry_equal()` functions, the properties of the
old nodes will still be accessed, causing a crash since the
CRDeclarations are already freed.
To fix that, keep the reference to the CRStylesheet, which owns the
CRDeclarations used by the theme nodes, around a bit longer, so it's
still possible to access the CRDeclarations inside the
"custom-stylesheets-changed" signal handler. This allows us to compare
the old theme nodes to the new ones since the CSS properties of both are
still valid.

gjs has gotten less forgiving about missing getters/setters, and
commit 6aa1b817 missed the missing getter in the base policy class.
Most notifications use a policy subclass that already provides a
getter, but at least Main.notify() and friends don't; unbreak them
by fixing the base class.

When a modal that's not on top of the modalActorFocusStack gets popped,
we shift the focus stack as described in popModal() to ensure the chain
remains correct. That however destroys the association of a modal actor
and its prevFocus actor on the focus stack, because the prevFocus actors
are now moved to different entries of the stack.
Now when a prevFocus actor gets destroyed, we don't handle that case
correctly and search for the modal actor that was associated with the
prevFocus actor before the stack was shifted, which means we end up
unsetting the wrong prevFocus actor.
So fix that and search the stack for the prevFocus actor which is being
destroyed instead to unset the correct entry.
Thanks to Florian Müllner for figuring out the actual issue and
proposing this fix.

StThemeNodes are built around the assumption that they're "immutable",
that means they are created once with certain parameters (that resolve
to certain css properties) and then replaced with new ones in case those
parameters changed.
Changes to the internal information stored by theme nodes (i.e. the css
properties, font names or the cached scale-factor) are not all handled
the same though: For changes to the font or the scale-factor we remove
all theme nodes from the cache and let the widgets which are on stage
generate new theme nodes. For changes to the css properties/the
stylesheet, we invalidate the properties of all theme nodes but keep
them in the cache using `_st_theme_node_reset_for_stylesheet_change()`.
So be a bit more consistent and handle changes to the css-properties/the
stylesheet stored by StThemeNodes the same way as changes to the font or
scale-factor.

Theme node invalidation stops at unmapped widgets, and widgets
that forget to chain up to the default ::style-changed implementation.
This may leave stale nodes that were invalidated on
StThemeContext::changed, but are still set on widgets, and maybe
used for CSS property lookups.
Make sure that theme node invalidation happens always by moving
propagation outside the vfunc, and ensure the theme nodes are reset
across the full actor tree. Emission of ::style-changed, and obtaining
a new theme node may be delayed till when the actor is mapped.
The theme node is also cleared after unparenting an actor to avoid
stale references.
This ensures that all widgets get their theme node cleared after
stylesheet changes, instead of maybe being left with a theme node
that's been cleared of all its properties.
