gjs now has an internal mainloop that it can spin to resolve
module imports. That loop uses the thread default context,
so its possible that other sources, namely from mutter, get
dispatched when iterating the context. If that happens before
mutter is properly initialized, this will lead to a crash.
GjsContext needs to iterate its internal mainloop when initializing
to resolve internal modules, to avoid iterating Meta's mainloop and
triggering events before Meta is ready we will initialize the Shell
global and thus the GjsContext (js_context) before Meta.
Once GjsContext is initialized, we can call meta_context_setup().
Once Meta is setup and started, we'll run init.js which uses GJS'
internal promises API to set a "mainloop hook". The mainloop hook
is run immediately after the module returns so GJS will not attempt
to iterate the main loop again before exiting.
Also adjust the 'headlessStart' test to not wait for the
MetaContext::started signal, as that signal has now already
been emitted when the code is executed.

get_size() in _syncAnimationSize() can't be called until the actor
has a parent, otherwise we'll get an error for calling
st_get_theme_node() prior to the actor being on a stage.
_syncAnimationSize() is called asynchronously via
textureCache.load_sliced_image() and there is currently no guarantee
the actor will actually be "loaded" prior to calling it.
This becomes a more obvious error/issue when refactoring parts of the
Shell loading to also be asynchronous.

We are about to port the helper proxy to GApplication, which means
that it will establish a display connection before exporting its
D-Bus name. That means that the compositor must be able to respond
to a roundtrip request to avoid locking, so don't block on the proxy
becoming available.

Now that we track apps instead of instances, we can make the menu
items activatable, because the corresponding action is no longer
app specific (like activating a particular tab): We can simply
activate the app, which hopefully will bring it to the foreground
again.

The background apps menu currently tracks instances rather than
apps. That matches the behavior of `flatpak ps` and can be useful,
for example when one particular instance runs out of control.
But as we don't include any information that allows to actually
distinguish between instances, multiple instances appear simply
as duplicated app entries.
Given that a menu is too limited for detailed information, stop
representing individual instances, and track apps instead.

Provide a reasonably public way to register and unregister search
providers, without adding too much API.
`Main.overview.searchController` provides access that may be generally
useful, while `SearchController.addProvider()` and
`SearchController.removeProvider()` provide a simple interface for
extensions.

We started to support Soup3 in GNOME 41, and used it by default
since GNOME 43. This should be enough time for distros to adapt,
so GNOME 45 looks like a good moment to drop the old Soup2 support.

Since we started to support the color-scheme preference, extensions
should be able to provide appropriate variants (if they deal with
colors).
So look for a variant with -dark/-light suffix before using the
plain stylesheet.css, and reload extension stylesheets on
color scheme changes.

The IBusCandidatePopup can get 'stuck' in an active, visible state if
it is on-screen at the point when the input method is changed to a method
that doesn't use such popup (e.g. regular English).
Force the candidate popup to close when the engine is changed.
It will reappear (via regular lookup table update signal) if/when it is
next required.

Calling _teardownPipeline() before _tryNextPipeline() was actually not a
good idea, it sets the pipelineState to STOPPED, which means we can't try
any of the following pipelines anymore.
Instead what we want to do is set the pipeline state of the old pipeline to
NULL when trying a new one, without calling _teardownPipeline() for that.

This pipeline imports dmabufs and does format conversion using GL.
The `video/x-raw(memory:DMABuf)` filter ensures format negotiation
between `pipewiresrc` and Mutter will only succeed if Mutter advertises
dmabuf support as well, falling back to the next pipeline otherwise.
Using this pipeline frees Mutter from downloading buffer content on the
main thread which can have a big impact on compositor performance.
Doing format conversion on the GPU should further improve the overall
performance on most hardware.

When the screencast dbus service crashes due to gstreamer, we should also
handle that and not pretend to continue recording.
Let's listen to g-name-owner changes for that and then also send a
notification about it.

Make sure gnome-shell gets notified of errors that happen during screen
recording using the screencastService, so that it can properly notify the
user about the error and tear down its state, too.

Pipewire versions < 0.3.67 may not fail immediatly on negotiation
errors, thus use the last/fallback pipeline directly.
Technically, a similar recent version of Wireplumber is required
as well, but we can't check that easily and the combination of old
Wireplumber and new Pipewire is quite unlikely.

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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2197>
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.

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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2742>
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.
