After porting the more complex cases - in particular those that
affect a module's API - we are left with straight-forward D-Bus
method calls that can be moved to promise-based wrappers in one
go.
For consistency, this also switches from Remote to Async where
the call result is ignored.

Screenshots use `%Y-%m-%d %H-%M-%S` for the timestamp, which has the
advantage of allowing proper lexicographical sorting.
The screencast file name pattern, on the other hand, uses
locale-dependent expansions, which break sorting based on file name, and
introduces the chance of potentially invalid characters on different
file systems.

ES modules do not allow exports to be overriden, in anticipation
of the ESM port add a `setCurrentExtension` utility which will
throw if used in the shell. This is tested using a conditional
import of Main.

We currently decide at build time whether to include screencast
support, based on whether the required gst/pipewire library headers
are installed.
That check is imprecise, because having the library headers available
at build time doesn't necessarily mean that the libraries are there
at runtime, or that the corresponding typelibs are installed.
It makes more sense to check the requirements at runtime, so prepare
for that by installing the screencast service unconditionally, but
bail out early if the dependencies aren't met.

If one of these libraries breaks its GIR API in future, then upgrading
packages unrelated to gnome-shell might pull in the newer version,
causing gnome-shell to crash when it gets a newer GIR API that is
incompatible with its expectations. For example, this seems to be
happening in Debian testing at the moment, when GNOME Shell 41.4
imports GWeather and can get version 4.0 instead of the version 3.0 that
it expected.
Adding explicit API versions at the time the newer version is released
is too late, because that will still let the newer version of the GIR API
break pre-existing GNOME Shell packages. Prevent similar crashes in
future by making the desired versions explicit.
This is done for all third-party libraries except GLib, similar to the
common practice in Python code; if GLib breaks API, then that will be
a disruptive change to the whole GLib/GObject ecosystem, regardless.
Gvc, Meta, Shell, Shew, St are not included because they're private
(only exist in a non-default search path entry).
Clutter and Cogl *are* included, because we need to import the fork of
them that comes with Meta, as opposed to their deprecated standalone
versions.

If the finish function isn't specified, promisify will now try
to use the async name without '_async'/'_begin' suffix (if any)
and '_finish' appended.
Everything except IBus uses a variation of that pattern, so there's
quite a bit of boilerplate we get to remove…

The current preference API - buildPrefsWidget() - predates client-side
decorations. While extension authors have been finding ways around
the limitation of not having access to the window/titlebar, the change
to the new Adwaita API seems like a good time for an updated API that
officially provides that access (as far as allowed by libadwaita).

Adapt the new GNOME platform API for the upcoming 42. This makes
sure that we get the latest version of the stylesheet, as well as
support for the new dark mode.
Using the dedicated preference API also gives extensions with more
complex preferences an easier and standardized way for implementing
multi-page preferences.

The error UI comprises the bits that are actually custom. Splitting them
out from the off-the-shelf window makes it easier to replace the dialog
with libadwaita's dedicated preference window.

The REPLACE flag we currently pass is useless, as replacing the service
is disallowed when not started with the ALLOW_REPLACEMENT flag.
Fix this by adopting a more standard pattern where replacement is always
allowed, but only actually requested when `--replace` is passed on the
command line.

All fd.o Notifications signals are emitted for a particular notification,
so debugging aside, only the owner of said notification has a legitimate
reason to act on it.
So far we (and other implementations like the old notification-daemon)
have relied on the client-side to properly filter the signals (like
libnotify), but at least the QT implementation is known to not do
that.
Enforce correct client behavior by only emitting the signal to the
original sender.

Instead of testing if the videos directory exists and using the home
directory otherwise, just try to create the target directory. This
aligns with how the screenshot UI handles the screenshots folder, and
it's convenient for putting screencasts into a subdirectory.

Like the main gnome-shell process, the extensions service loads code from
extensions. It therefore makes sense to prevent GType name clashes there
as well, just like we already to in the gnome-shell process.
This may break some extensions that use the old type name in .ui files,
but they can be fixed easily by specifying an explicit GTypeName.

Replace deprecated functions with their direct replacements:
- dep.get_pkgconfig_variable() → dep.get_variable()
- prg.path() → prg.full_path()
- source/build_root() → project_source/build_root()
In one case we need meson.global_source_root() that was only
added in meson 0.58, so bump the requirement to that.

Showing multiple preference dialogs at the same time (for instance
by repeated `gnome-extensions prefs` calls) may or may not work as
expected, depending on whether any of the dialogs is modal or not
(read: opened via the Extensions app).
The easiest way to address this is to disallow more than a single
dialog at the time. It's arguably also the more predictable behavior,
and means extensions don't have to deal with inconsistent state
caused by multiple dialogs.

GTK4 relies entirely on refcounting for cleanup (that is,
there is no longer a destroy() method that forces a dispose
run regardless of the refcount).
Unfortunately that makes cleanup harder in (some) language
bindings, where an object may be kept alive implicitly by
closures etc.
Address this by releasing the hold count when the window
is closed rather than when it is destroyed.
This isn't the most elegant, but it ensure that the service
doesn't get stuck if an extension doesn't carefully clean
up everything in its prefs widget.

If parsing the pipeline fails for some reason, we currently end up
with a zombie session that leads to a stuck recording indicator in

Instead, properly tear down the session to allow mutter and gnome-shell

The current gstreamer pipeline performs quite bad on slower machines and
is dropping lots of frames, improve the pipeline by changing a few
things:
- Use threads for videoconvert and improve speed of videoconvert by
disabling some unneeded things
- Add a queue before the encoding step, this allows the encoder to work
at its own pace and will lead to a lot more stability
- Remove the fixed quantizer and only set a max quantizer, this helps
quite a bit with performance
- Change the deadline parameter of vp8enc to 1: This makes the encoder
go into real time mode, which will make it a lot faster
- Set cpu-used to 16, the maximum possible value.
- Set static-threshold to 1000, static-threshold is the motion detection
threshold, and while a value of 100 is recommended for screencasting in
the gstreamer documentation (see [1]), using 1000 appears to perform a
lot better and still outputs fairly good quality
- Set a larger buffer size than the default size, this seems to get a
bit more stability during high load scenarios
All in all, those changes make the pipeline drop no more frames when
recording at 30 FPS and 2K screen resolution. That was tested on a
fairly recent mobile core-i5 processor.
Also, because we now have two %T replacement strings for the number of
threads, we need to switch to replaceAll(). For that to work, we have to
put the %T matching expression into quotes.

For the screensaver service, it is quite normal that a consumer only
subscribes to the "ActiveChanged" signal without calling any methods.
The result is that we don't know about the consumer, and shut down
the service anyway after we hit the timeout.
If this happens, we break functionality like gnome-settings-daemon's
screen blanking on idle.
Fix this by simply disabling auto-shutdown for the service, which
also reflects the expectation that the screen saver service is
always running in a GNOME session.

With the previous preparations in place, it is time to take the plunge.
As both the app and the portal use the same small library for handling
external windows, port everything at once to avoid the hassle of building
and installing two versions of the library.
With the portal using GTK4 now, all extensions must port their preference
widgets as well.

We currently use separate frames for the details expander and the
expanded details. That layout works as long as frames are boxy (as
in the default GTK3 style), but breaks down with rounded corners
(as in the default GTK4 style).
In order to work with either style, adapt the layout to use a single
surrounding frame and appropriate borders as separator.

Move the screencasting into a separate D-Bus service process, using

For fd.o notifications, we are taking the sender's PID into
account when associating notifications with sources (mainly
to deal with notify-send).
This broke when the implementation under the well-known name
was moved into a separate service, as the implementation in
gnome-shell will now always see the public notification-daemon
as sender.
Restore the old behavior by resolving the sender PID in the
separate service, and pass it as hint to the implementation
in gnome-shell.
