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.

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*).

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 :-)

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.

When adapting the check to the new versioning check, we just blindly
copied the old behavior for stable/unstable versions:
- stable releases must have matching major numbers
- unstable releases must match major and minor ("alpha", "beta", "rc")
That worked for the old even/odd scheme, but now has the absurd effect
that we consider an extension that lists "40.alpha" in its shell-version
incompatible with "40.beta", but compatible with "40.2".
At least this provides us with a good opportunity to reconsider the
behavior. While it is true that breakage is much more likely between
unstable releases, in practice extensions are either following shell
development closely or update once around the time of a stable release.
For the former, the stricter check isn't usually too useful (as the
extension releases around the same time as gnome-shell anyway).
For the latter, it's annoying that ".rc" is treated differently from
".0" and requires an update to become compatible.
The latter is also by far the more common case, so update the check
to only match on the major version regardless of whether a release
is stable or unstable.

This ports the runDialog changes of [1] to the underlying history
component, where they can benefit looking glass as well: the history is
now responsible for trimming the input and deciding that it shouldn’t be
stored if empty. (Note that _setPrevItem and _setNextItem already
skipped updating the history if the entry was empty.)
Since both users, runDialog and lookingGlass, also need the trimmed
input for other reasons – runDialog to avoid issues when interpreting
the command as a file path (if it can’t be executed as a command),
lookingGlass to decide whether a command should be run at all – have
addItem return the trimmed input. (runDialog and lookingGlass are not
yet changed to take advantage of this – that will be done in separate
commits.)

With the new versioning scheme, the previously-minor version gets
shifted up to major, and unstable releases are marked by non-numeric
"versions" rather than uneven numbers. Reflect that in the extension
version check.
