If the user clicks Not Listed? to enter ask for username mode, clicks
cancel, and then attempts to log in via the user list, the user will see
"Authentication failed" after correctly typing the password, and then
will become stuck in an empty screen with just the gray noise background.
The problem is, we forgot to disconnect from the signal that's waiting
for the next button to be pressed on the username entry screen. Since
the signal handler that executes here is expecting the username to be
input, and isn't prepared for us to have switched back to user list,
various bad things happen. We try to start two gdm-password
conversations at once, for instance, one using the user's password as
the username. I stopped investigating here, because it's easy to fix by
disconnecting from the signal at the right time.

Since commit 82950ecea, we acknowledge pending messages when closing a
chat notification for a channel we are handling to prevent the channel
from popping up again immediately. While this isn't an issue for channels
we don't handle, the unread messages of the destroyed notification are
still considered for the messages indicator in the top bar, which is
clearly confusing (in particular when we end up showing the indicator
without any notifications in the list). As it's arguably correct to not
meddle with a channel handled by someone else, just reset the cache of
pending messages to address this issue.

Nowadays, the user interface has mostly stabilized with most changes
happening under the hood. As a result, extensions written for previous
versions of GNOME Shell are very much expected to keep working on
updates, if it wasn't for the version check that requires a version
bump in the extension metadata. There has been a setting to disable
that check for a while, but it's existence isn't widely known (hence
the common perception that "everything breaks on updates"). While
there is still some risk that an out-of-date extension can be enabled
without error, but fails spectacularly later (where we cannot catch
the exception), it is reasonably small by now when compared to the
~95% of extensions that can be "unbroken", so swap the default value
to disable version checks by default.

Mutter's plugin destroy event doesn't happen if a window is hidden
when it gets unmanaged so we also need to handle the
MetaWindow::unmanaged signal to check whether the parent should
dimmed.

meta_window_foreach_transient() iterates through all transients of a
window, not only direct transients. This means that simply checking if
a transient is an attached dialog isn't enough because it might be a
non-direct transient for the window we're checking, in which case we
don't want to dim the window.
In particular this fixes windows not getting undimmed when they have
more that one level of transient children and the direct transient gets
destroyed. In that case we would still find at least one non-direct
transient child and decide to keep the window dimmed.

Commit bd6e7f14d1 reimplemented the cycle keybindings to
fix cycling between more than two windows, but the approach
of highlighting cycled windows by actually focusing them has
the drawback that cycling messes up the MRU order of windows.
To fix this, only change the window focus when the operation
finishes, and use a dedicated actor that draws a border around
a window clone for highlighting.
https://bugzilla.gnome.org/show_bug.cgi?id=771063
There's no particular reason for this actor to be reactive and thus
preventing input events to reach actors underneath, e.g. quickly
clicking on something while the popup isn't yet finished animating
out.

Mutter may capture the screen in multiple capture regions. If this is
done, take these images and composite them onto one large image, which
is then passed into the gstreamer source.
When clutter gives us multiple captures (multiple cairo_surface_t's),
composite them into one large image and use that as final screenshot
result. This makes screenshooting work when mutter uses multiple views.
