Introduce a fallback mechanism for gstreamer pipelines that allows to
define multiple pipelines and prefer them over each other.
The way this works is that we introduce a new STARTING PipelineState.
While the Recorder is in that state, it is allowed to tear down the
current pipeline and start another one whenever an error happens, this is
used to try multiple pipelines in a fixed order until a working one is
found.
Right now there's just a single pipeline using the existing vp8 encoder, the
actual new encoders and pipelines will be added in a separate commit.

The check for the Pipewire version was originally introduced in
d32c0348 which states:
> Since it is not clear yet when a proper solution will arrive,
> this makes use of `always-copy` as a workaround for now and
> should be reverted once it is no longer needed.
The check for a stable Gstreamer version with the mention proper fix was
introduced in d7b44319 and carried for the 43 cycle.
By the time Gnome 44 will be released all distros should have had enough
time to update their Gstreamer version - or backport the patches, in
case of not ustream-supported versions.
Thus lets drop it now.
Note: `always-copy` is not suitable for dmabuf buffers as it copies via
mmap.

Right now when we tell gstreamer to move the pipeline to the state
PLAYING, we pretend that happens immediately and set our PipelineState
to PLAYING right afterwards.
In reality though it's more complicated than that: Gstreamer changes
states asynchronously and set_state() returns a Gst.StateChangeReturn.ASYNC.
In that case we should wait until the according STATE_CHANGED event happens
on the bus, and only then set our PipelineState to PLAYING.
Since the STATE_CHANGED event will also happen when set_state() returns
SUCCESS, we can use the same async logic for that.

Gstreamer can produce various errors, we shouldn't pretend those don't
exist and go on as usual when one happens. Instead, when an error
happens, tear down the pipeline, set our PipelineState to the new ERROR
state and bail out with a proper error message.

We're tracking three different state-machines in the Recorder object:
The state of the gstreamer pipeline, the state of the screencast
session, and the sender of our dbus invocation that might vanish.
Properly handling errors that might appear in any of those three "black
boxes" is not easy, especially tearing down the other two when one of
them breaks.
So refactor the error handling here: Add a single error path for each of
those three states we're tracking, and make them all subsequently call
the _bailOutOnError() method. From there we tear down the other states and
call the error callbacks.

The pattern has become a lot less common, not least indicated
by the removal of the HeaderBar:subtitle property. And in this
case we are including an icon in the subtitle, which looks
completely out of place.
Address this by moving the URL/security information into a
popover menu, inspired by the similar drop-down in GNOME Web.

Years ago, the function used to clean up the cache when the
window was closed. But now that an ephemeral data manager is
used, nothing is cached anymore and the function is left as
a mere wrapper around this.destroy().

The events that the draggable uses to initiate a drag operation
are the same as the ones a click action consumes for clicks.
It is still possible to combine the two, but it's finicky and far
from being straight-forward. To make this easier, add a dedicated
addClickAction() method to draggables that takes care of the
setup before adding the action to the draggable actor.
In the longer term, we'll want to turn DND into an action, and
have something like GTK's gesture group to allow combining actions
that would otherwise step on each other's toes.

Actions provide a higher-level API than event handlers, not unlike
GTK's event controllers (albeit less complete). Allowing them to
take care of the low-level bits where possible is generally a good
idea.
Menu items are a very straight-forward case, with a good amount
of code saving, so port them over.

The handler dates back to commit 50f248ec5b in 2011, and is
part of the original hack of making the activities button a
PanelMenu.Button while suppressing its menu.
By now, panel buttons without a menu have been properly supported
for years, but somehow that bit of the hack stuck around, even though
it is no longer actually needed (probably since the introduction of
DummyMenu.

When we can't detect a headphone by form factor, we do a string
match on the port name. A match on 'Headphone' isn't less likely
to be valid than a match on 'headphone', so make sure we ignore
capitalization.

After the introduction of implicit grabs in Clutter, a release
event will now always be delivered to the actor that received
the corresponding press event.
This results in surprising behavior when moving the pointer
while pressed, as a button release will always activate the
original item, even when the pointer moved to a different item
or outside the menu altogether.
Address this by checking the hover state (that is, whether
the item contains the pointer actor) before activating it.

When a WindowPreview is being destroyed, the class default handler for
the `destroy` signal is responsible for destroying its child actors.
This happens after the emission of the `destroy` signal, i.e. after
`WindowPreview::_onDestroy()` has been run.
The destruction of the WindowPreview's child actors now triggers a
re-pick, but due to WindowPreview having already being marked as
`CLUTTER_IN_DESTRUCTION`, it will not be picked, resulting in a `leave`
event if the cursor was on top of the WindowPreview at the time
`destroy()` was called on it.
So this leads to `WindowPreview::vfunc_leave_event()` being run after
`WindowPreview::_onDestroy()`, which means the idle started by the leave
event handler will not be removed and ends up accessing actors after
they have already been destroyed.

Dash labels are children of the main uiGroup and so could be destroyed
before their logical-owner DashItemContainer during shutdown.
This implies that we could destroy them twice. To avoid this, unset them
when destroyed.
This is mostly visible when using dash-to-dock, but it's still
technically possible with upstream code:

The left/right navigation between top bar buttons is usually
handled by a key-press handler on the button's menu.
However when a DummyMenu is used, the button itself serves as
fake menu actor and will get grabbed when "opening" the menu.
Due to that grab, the event is not propagated to the stage,
and regular keynav does not work.
To avoid the focus getting stuck in that case, add an explicit
key-press handler that bypasses the grab.

When the user clears all notifications from the notification menu UI, it's
possible for a queued notification to be destroyed after the currently displayed
notification. The removal of the currently displayed notification is not
processed until the notification menu is closed (due to `this._bannerBlocked`).
By then, it's possible that `_notificationRemoved` has already been overwritten
when `_onNotificationDestroy` is invoked with another (queued) notification.
This eventually results in a notification banner that cannot be removed by the
user as the notification object needed to do so has already been destroyed.
Fix this by only assigning to `_notificationRemoved` if `this._notification ==
notification`.

Emitting this signal is broken right now: We check for a length of 0 on
this._objects[objectPath], but the
`this._objects[objectPath][interfaceName] = null` we do before the
check doesn't actually remove the key, it only sets the value to null,
leaving the key around and thus the amount of entries in the object doesn't
change.
Fix that by using the delete statement instead, "delete" properly removes
the key and thus affects the amount of entries in the object, making our
length === 0 check effective.

Both :icon-name and :gicon are propagated to the internal QuickToggle
with property bindings. However the bindings are set up in the wrong
order:
:icon-name is a convenience property to set :gicon to a ThemedIcon
of the given name. That means binding :icon-name first will correctly
set the underlying StIcon's :gicon, but then the :gicon binding will
set it again to null.
Fix this by swapping the order in which the bindings are set up,
so that it works for both properties.

Commit 9d75d777c7 introduced code to hide the subtitle of the
quick setting toggle when it matches the title of the toggle.
That's because NetworkManager tries to make the network names
more palatable on its own, and reports that the name of single
wired networks is "Wired" even if it may have another name.
What that commit failed to account for, however, is that there are
other circumstances where we end up with a subtitle is exactly the
same of the title. For example, when turning off Wi-Fi or mobile
broadband connections.
The behaviour of commit 9d75d777c7 is safe enough to be applied
on other device-backed connections, so do it.

When a window is in the background and should not have the cursor on top
of it, its _cursor will be null. By getting the texture through it, we
add this extra check, which was missing before, leading to a cursor
drawn at 0, 0 on windows where it should not have been drawn.

909616b208 seems to have wrapped window actors in a container, so the actor.has_pointer check started failing. Instead, switch to meta_window_has_pointer () which doesn't rely on window actor implementation details.
We check for existence of has_pointer first just in case someone attempts to run gnome-shell 44.1 with mutter 44.0 which does not have the function exported publicly yet.
