clutter_text_get_selection() creates a copy of the selected text which
gets passed to st_clipboard_set_text() which creates its own copy. The
copy returned by clutter_text_get_selection() however never got free'd.

The HasCalendar property reflects whether there are any views, and views
change either when clients appear/disappear or when the time range changes.
However we currently only emit the PropertiesChanged signal for the former,
fix that.

The shell mime sniffer goes through all the files in a directory,
however in case a file content type is not recognized, the GIO function
g_file_info_get_content_type() may return NULL, causing a crash when
looking up into the content type tables, as they are supposed to contain
strings only and they use `g_str_hash` has func, which doesn't support
NULL values.
So, in case we get an invalid content type, let's just ignore it,
without adding it to the cache as we do in the nautilus code that was
inspiring the sniffer.

As outlined in commit 36b8dcbe07, we can end up with wrong icons
if the icon theme changes right after a GTK theme change to/from
HighContrast triggered a theme reload.
That's because when we reload icons for the new icon theme, there
are already pending requests due to the icon-style change; those
requests are simply re-used for the new icons, with the existing
icon infos from the old theme.
The above commit applied a simple work-around by changing the
icon theme before the GTK theme, but that only works for the
HighContrast switch in our own UI.
It turns out that Settings also uses the "wrong" order, so the
issue still reproduces with the Universal Access panel.
So instead of relying on everything changing the settings in the
order we expect, cancel all ongoing requests on icon-theme changes.

Since the `MetaSelection` of the global `StClipboard` is private (and
should be), there is no reasonable way for extensions or external code
to query the supported mime-types.
Add `st_clipboard_get_mimetypes()` so this can be queried without
poking around in private code.

Since e06109c23c we keep old theme nodes
valid during the emission of the "custom-stylesheets-changed" signal.
It turns out that we might still look up the file of a stylesheet using
the files_by_stylesheet hashtable during the emission of that signal,
causing a crash because the assertion in _st_theme_resolve_url() fails.
So fix that and remove the stylesheet entry from the files_by_stylesheet
hashtable after emitting the "custom-stylesheets-changed" signal. And to
be consistent, also remove the entry from the stylesheets_by_file
hashtable after emitting the signal.

`StBoxLayout` has a couple properties (`vertical` and `pack-start`)
improperly referenced as signals, and is somewhat unclear these
properties are wrappers around the underlying `ClutterBoxLayout`
properties.
Fix these up and add references to the underlying properties, rather
than redescribing them.

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.

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.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2709
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.

Commit d76162c1c0 removed the ability to pass an extension UUID to
the Extensions app, when we moved the dialog to a portal and made
gnome-shell use it instead of spawning the extensions app.
However that missed that many extensions called out to the app to
open their own prefs.
While extensions are encouraged to switch to the new openPrefs()
convenience method added in commit 8030d9ad32, restore the old
behavior with a small script under the old gnome-shell-extension-prefs
name that either calls out to the portal or launches the app.

We currently always ignore the minimum width of the hint actor and
request/allocate the preferred width. This can be problematic with
labels with long text, where we should rather ellipsize the text
than allow the entry to grow indefinively.

When building the list of window PIDs, it's possible Mutter doesn't know
about the PID the client has and meta_window_get_pid() will return 0. We
should handle this case by not adding the PID to the list of PIDs
instead of adding an invalid one to it.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1184
MetaWindows get_pid() API changed to use the client PID, which also
works for Wayland clients instead of only X11 clients now. This API
returns 0 instead of -1 for invalid PIDs, so update our check according
to that.

Each node stores the scale factor in place when it was created.
Creating nodes with the same style, but with different scale
factors, yields different nodes.
Use the node's scale factor instead of retrieving the context's
one.

Since commit 6a42d77261 we invalidate the
cached properties for each theme node on stylesheet changes by iterating
over the hashtable of the theme context instead of listening to the
signal in each individual theme node.
That commit forgot one particular node though that's not stored in the
hashtable, but using the `priv->root_node` property instead: The theme
node that belongs to the stage.
So make sure we also invalidate the cached properties of the stage theme
node on stylesheet changes. This fixes various crashes that happened
with extensions providing custom stylesheets (emitting the
"custom-stylesheets-changed" signal on every extension enable/disable),
trying to access an already freed CSS property of the stage.

Just like StIcon does, we should use a container widget for the fallback
app icon that we get using the cairo surface property. It's needed
because the widget returned by shell_app_create_icon_texture() can be
resized freely, while we want the aspect ratio of the actual texture to
remain the same.
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2578
Commit 7ff7fb5d3b forgot to clear the
`priv->icon_texture` actor when returning from st_icon_update(), which
means we don't always switch to an empty icon if both gicon properties
are set to NULL.
Fix this and destroy the actor before returning early from
st_icon_update().

Commit c89d6a633 introduced a default fallback icon that would be displayed in
case the main gicon or the fallback gicon wasn't set or failed to load.
This broke the use case where a StIcon is created but no main icon or
fallback icon are set on purpose, for example the appindicator extension
which always creates a StIcon to represent icons in menu items but the
actual icons are only set if the application provides one, leaving the
menu showing the default fallback ("image-missing") icon for all menu
entries that don't actually have an icon provided by the application.
Fix that by only using the default fallback icon if the provided one
failed to load.

The app-cache code currently stores the folder translations in a hash
that can be accessed via shell_util_get_translated_folder_name().
This hash uses the filename (inc. extension) for the "desktop-directory"
as key which causes an issue when trying to find the translation
on AppDisplay._findBestFolderName() which gets categories (folder names)
from the app info which doesn't contain the ".directory" extension.
Fix that by storing the filename without extension as the hash key for
the cached folder translations.
