There are a couple of places left where we still use the old
indentation style, update them before making code changes.
After that, there are only a couple of non-type-safe comparisons
left of legacy style, so change those as well while we're at it.

Since IBus does not provide this information right away, we
so far cannot do much about providing a truthful anchor position
for the preedit text. But with the Mutter API in place it will
be up to this object to do so in the future.

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 considered any ConnectFlag value major than SWAPPED as invalid, while
it's technically not fully true as we need to ensure that the passed
value is respecting the whole flags mask.
In fact, per se SWAPPED|AFTER (> SWAPPED) is a valid value (even if we
don't support the AFTER value).
But this makes the check more future-proof.

While untracking an object we used to compute it's proto for each signal
we were disconnecting from, while this is not needed when we're just
iterating over all the same owner signals, so let's add few more
functions to compute an object prototype, and repeat the disconnections
in the simplest way we can.

We used to create a temporary array of signal tracker keys and then to
iterate through them in order to untrack the objects, but the Map's can
be iterated directly so let's just use their native forEach.

Introduce a new class, EventEmitter, which implements signal
handling for pure JavaScript classes. EventEmitter still
utilizes GJS' addSignalMethods internally.
EventEmitter allows static typechecking to understand the
structure of event-emitting JS classes and makes creating
child classes simpler.
The name 'EventEmitter' mirrors a common name for this pattern
in Node and in JS libraries.

Both bluetooth and screencast support are based on build checks
right now. However in both cases, the dependency is only consumed
at runtime via the typelib, so let's actually check for that.

The screencast portal supports recording a single window,
and presents a list of open windows when that option is
selected. To allow updating that list when windows are
opened or closed, add a new "WindowsChanged" signal that
the portal can listen to.

We currently assume that any '::destroy' signal on a GObject type
has the semantics of the ClutterActor/GtkWidget signal, and should
therefore result in all signals being disconnected.
But we already have a case where the assumption doesn't hold: ShellWM
uses '::destroy' for the closing animation of windows, and the ShellWM
object itself remains very valid after the emission.
So rather than making assumptions about '::destroy', check objects
against a list of destroyable types that are explicitly registered
as such.

There are cases where we want to connect to a number of signals
for the lifetime of an object, but also other signals for a
limited period (say: between show and hide).
It is currently not possible to use disconnectObject() for the
latter, because it will disconnect all signals.
To address this use case, add a small class that can be used as
a transient signal holder, while still benefiting from autocleanup
by proxying the real owner.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2221>
The 'destroy' signal currently doesn't work with connectObject(),
because the handler is only connected after the signal tracker's
own destroy handler, which disconnects all handlers.
Address this by using connect_after for the cleanup handler, so
that other destroy handlers run before it (unless they also use
ConnectFlags.AFTER, but well *shrug*).
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2221>
Start using the new methods to simplify signal cleanup. For now,
focus on replacing existing cleanups; in most cases this means
signals connected in the constructor and disconnected on destroy,
but also other cases with a similarly defined lifetime (say: from
show to hide).
This doesn't change signal connections that only exist for a short
time (say: once), handlers that are connected on-demand (say: the
first time a particular method is called), or connections that
aren't tracked (read: disconnected) at all.
We will eventually replace the latter with connectObject() as
well - especially from actor subclasses - but the changeset is
already big enough as-is :-)
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1953>
The module exports a `addObjectSignalMethods()` method that extends
the provided prototype with `connectObject()` and `disconnectObject()`
methods.
In its simplest form, `connectObject()` looks like the regular
`connect()` method, except for an additional parameter:
```js
this._button.connectObject('clicked',
() => this._onButtonClicked(), this);
```
The additional object can be used to disconnect all handlers on the
instance that were connected with that object, similar to
`g_signal_handlers_disconnect_by_data()` (which cannot be used
from introspection).
For objects that are subclasses of Clutter.Actor, that will happen
automatically when the actor is destroyed, similar to
`g_signal_connect_object()`.
Finally, `connectObject()` allows to conveniently connect multiple
signals at once, similar to `g_object_connect()`:
```js
this._toggleButton.connect(
'clicked', () => this._onClicked(),
'notify::checked', () => this._onChecked(), this);
```

We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.
But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).
And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

There's a few things that are really unncessary to log without any
debugging enabled, for example "Getting parental controls for user", so
remove that.
Other things can be useful, so use console.debug() to log those.
Especially the warning in showAppInfo() we don't want log by default as
it spills tons of messages during shell startup (the async
initialization of the malcontent manager takes some time).
While at it, also make the !HAVE_MALCONTENT message a bit more accurate.

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…

Use GLib's spawn_async() instead of Gio.SubprocessLauncher() which does
not support the child setup function to start ibus-daemon.
This way we can restore the NOFILE limit prior to run the ibus-daemon.

The code to highlight matches did not properly escape the passed in text
as for markup before adding its highlighting markup. This lead to some
search result descriptions not showing up, because their descriptions
contained characters, such as "<", that would have to be escaped when
used in markup or otherwise lead to invalid markup.
To work around this some search providers wrongly started escaping the
description on their end before sending them to gnome-shell. This lead
to another issue. Now if the highlighter was trying to highlight the
term "a", and the escaped description contained "'", the "a" in
that would be considered a match and surrounded by "<b></b>". This
however would also generate invalid markup, again leading to an error
and the description not being shown.
Fix this by always escaping the passed in string before applying the
highlights in such a way that there are no matches within entities.
This also means that search providers that escaped their description
strings will now show up with the markup syntax. This will have to be
fixed separately in the affected search providers.

This signal announces the preferred commit mode of the preedit text when
the input context is reset. Keep this mode around, and ensure to honor this
mode (e.g. maybe commit the preedit string) whenever the input method would
be reset.
This is delegated to the internal layers, so propagate this mode via
clutter_input_method_set_preedit_text().

!1940 added support for soup 3, including a fallback to soup 2.4
where the newer version isn't available.
Unfortunately it missed that libgweather has a hidden soup dependency,
and now gnome-shell fails to start if a weather location has been set
up and soup 3 is available.
We don't have a good way to detect that case, so hide the soup 3 support
behind a build option. Distributors are expected to switch it at the
same time as libgweather.

We have initTranslations() for binding an extension's
gettext domain, but nothing to help with using gettext
from an extension.
Such help would be useful though, as an extension that
calls textdomain() like a normal application would
inadvertently changes the default domain for the whole
gnome-shell process.
Instead, extensions have to use domain-specific versions
of the gettext functions:
```js
const Gettext = imports.gettext.domain('my-extension');
const _ = Gettext.gettext;
```
Make this a bit easier by adding those functions directly
to the extensions object when initTranslations() is called,
then expose helper functions for calling them.
