5962ee7939 startup: Fix possible crash in startup notifications
A GAppInfo is not guaranteed to have a filename or an application (or
rather a desktop ID). Add a check for application_id to be non-NULL
before trying to call sn_launcher_set_application_id, which would crash
otherwise.

c7d14244b1 x11: Add STRING/UTF8_STRING targets for selection sources lacking them
The memory selection source was only providing the "text/plain" or the
"text/plain;charset=utf-8" mimetype, but not "STRING" or "UTF8_STRING",
which some X11 clients, like wine, are looking for. This was breaking
pasting from the clipboard in wine applications.

Fix this by adding those targets when they are missing and the selection
source provides the corresponding mimetypes.

e1c4e55880 x11: Handle selection windows being destroyed before new selection
Wine destroys its old selection window immediately before creating a new
selection. This would trigger restoring the clipboard, which would
overwrite the new selection with the old one. The selection window
however can also be destroyed as part of the shutdown process of
applications, such as Chromium for example. In those cases we want the
clipboard to be restored after the selection window has been destroyed.

Solve this by not immediately restoring the clipboard but instead using
a timeout which can be canceled by any new selection owner, such as in
the Wine case.

2f1f47d257 x11: Look up reason for selection clear events from XFixes
If the event originates from a XSetSelectionOwner request, the event
will contain a XFixesSetSelectionOwnerNotify subtype. The other
subtypes (meant for the selection window being destroyed, and the
client closing) are the situations where we mean to replace the

f5c8e0d96d window/x11: Don't stop early when trying to find default focus window
When trying to find a default focus window, the code iterates through a
queue of candidates with a timeout between each candidate. If the window
the current timeout is waiting for gets destroyed, this process just
stops instead of trying the next window in the queue.

This issue was made more likely to be triggered with the previous change
to the closed-transient-no-input-parents-queued-default-focus-destroyed
test due to the introduction of a wait, which can introduce a
delay between the two destroy commands.

5671f0a284 x11: Allow X11 clients to clear the selection
According to the XSetSelectionOwner libX11 documentation:

  [...] If the owner window it has specified in the request is later
  destroyed, the owner of the selection automatically reverts to None,
  but the last-change time is not affected.

This is indeed visible through the selection_timestamp field in
XFixesSelectionNotify events.

Use this to check whether the selection time is recent-ish (thus
likely coming from an explicit XSetSelectionOwner request) and honor
the client intent by setting a "NULL" owner. If the selection time
is too old, it's definitely an indication of the owner client being
closed, the scenario where we do want the clipboard manager to take
over.

This fixes two usecases:
- X11 LibreOffice / WPS clear the selection each time before copying
  its own content. Mutter's clipboard manager would see each of those
  as a hint to take over, competing with the client over selection
  ownership. This would simply no longer happen
- Password managers may want to clear the selection, which would be
  frustrated by our clipboard manager.

There's a slight window of opportunity for the heuristics to fail
though, if a X11 client sets the selection and closes within 50ms, we
would miss the clipboard manager taking over.

Flushing the X11 selection output stream may happen synchronously or

655a783891 x11: Don't stall on write_async()
If a write_async() comes up while we are flushing on the background,
the task will be queued, but not deemed a reason on itself to keep
flushing (and finish the task) after a property delete event.

To fix this, do not ever queue up write_async tasks (this leaves
priv->pending_task only used for flush(), so the "flush to end"
behavior in the background is consistent). We only start a
background flush if there's reasons to do it, but the tasks are
immediately finished.

All data will still be ensured to be transfered on flush/close,
this makes the caller in this situation still able to reach to it.

967966cdee x11: Flag flushes despite having less than the element size
If say we want 32bit data, but have 2 bytes stored, we would simply
ignore flush requests. Allow (and don't clear) the needs_flush flag
if we have less than the element size accumulated.

Instead handle this in can_flush(), so it's triggered whenever we
have enough data to fill 1 element, or if the stream is closing
(seems a broken situation, but triggered by the caller).

d08a8de265 window: Implement asynchronous popup moving
This commits adds support on the MetaWindow and constraints engine side
for asynchronously repositioning a window with a placement rule, either
due to environmental changes (e.g. parent moved) or explicitly done so
via `meta_window_update_placement_rule()`.

This is so far unused, as placement rules where this functionality is
triggered are not yet constructed by the xdg-shell implementation, and
no users of `meta_window_update_placement_rule()` exists yet.

To summarize, it works by making it possible to produce placement rules
with the parent rectangle a window should be placed against, while
creating a pending configuration that is not applied until acknowledged
by the client using the xdg-shell configure/ack_configure mechanisms.

An "temporary" constrain result is added to deal with situations
where the client window *must* move immediately even though it has not yet
acknowledged a new configuration that was sent. This happens for example
when the parent window is moved, causing the popup window to change its
relative position e.g. because it ended up partially off-screen. In this
situation, the temporary position corresponds to the result of the
movement of the parent, while the pending (asynchronously configured)
position is the relative one given the new constraining result.

ff381d1d52 constraints: Pass constrained relative coordinates to window impl
A placement rule placed window positions itself relative to its parent,
thus converting between relative coordinates to absolute coordinates,
then back to relative coordinates implies unwanted restrictions for
example when the absolute coordinate should not be calculated againts
the current parent window position.

Deal with this by keeping track of the relative position all the way
from the constraining engine to the move-resize window implementation.

845157c111 window/x11: Add freeze_commits()/thaw_commits()
Xwayland may post damages for an X11 window as soon as the frame
callback is triggered, while the X11 window manager/compositor has not
yet finished updating the windows.

If Xwayland becomes compliant enough to not permit updates after the
buffer has been committed (see [1]), then the partial redraw of the X11
window at the time it was posted will show on screen.

To avoid that issue, the X11 window manager can use the X11 property
`_XWAYLAND_ALLOW_COMMITS` to control when Xwayland should be allowed to
post the pending damages.

Add `freeze_commits()` and `thaw_commits()` methods to `MetaWindowX11`
which are a no-op on plain X11, but sets `_XWAYLAND_ALLOW_COMMITS` on
the toplevel X11 windows running on Xwayland.

It's possible that the resize operation finished prematurely by the user

client finally updates mutter will erroneously still have the watchdog timer
engaged from before until it times out, leading to resizes for the next second
