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.

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 :-)

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.

This get's rid of the single-indicator introduced in one of the latest
commits. This was causing the accessibility pill in the top panel
to have different padding from the keyboard layout pill.

Promises make asynchronous operations easier to manage, in particular
when used through the async/await syntax that allows for asynchronous
code to closely resemble synchronous one.
gjs has included a Gio._promisify() helper for a while now, which
monkey-patches methods that follow GIO's async pattern to return a
Promise when called without a callback argument.
Use that to get rid of all those GAsyncReadyCallbacks!

xgettext gained some support for template strings, and no longer
fails when encountering '/' somewhere between backticks.
Unfortunately its support is still buggy as hell, and it is now
silently dropping translatable strings, yay. I hate making the
code worse, but until xgettext really gets its shit together,
the only viable way forward seems to be to not use template
strings in any files listed in POTFILES.

ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.

Clutter originally cluttered its namespace with key symbols, before
prefixing all symbols with KEY. We still use the unprefixed symbols
occasionally, replace them so mutter can drop the deprecated symbols.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/808
Every since commit aa394754, StBoxLayout has supported ClutterActor's
expand/align properties in addition to the container-specific child
properties. Given that that's the only container left with a special
child meta, it's time to fully embrace the generic properties (and
eventually remove the child meta).

Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

We are currently inconsistent whether to put the operators in front
of the corresponding line or at the end of the preceding one. The
most dominant style for now is to put condition and first branch on
the same line, and then align the second branch:
let foo = condition ? fooValue
: notFooValue;
Unfortunately that's a style that eslint doesn't support, so to account
for it, our legacy configuration currently plainly ignores all indentation
in conditionals.
In order to drop that exception and not let messed up indentation slip
through, change all ternary operators to the non-legacy style.

Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.
We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.
So just omit braces consistently as mandated by gjs' coding style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
When destructuring multiple return values, we often use trailing commas
to indicate that there are additional elements that we are ignoring.
There isn't anything inherently wrong with that, but it's a style that's
too confusing for eslint - on the one hand we require a space after a
comma, on the other hand we require no space before closing brackets.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/607
We are currently inconsistent with whether or not to put a space
after catch clauses. While the predominant style is to omit it,
that's inconsistent with the style we use for any other statement.
There's not really a good reason to stick with it, so switch to
the style gjs/eslint default to.

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

When an InputSourceIndicator is destroyed, the InputSourceManager it was
connected to could (and probably will) outlive it (since the manager is
a singleton). If the InputSourceManager emits any subsequent signals,
the callbacks from the finalised InputSourceIndicator could be invoked,
and will reference finalised objects.
This can be triggered by running `pkexec true` from a gnome-terminal
window, then calling `pkill pkexec` from another terminal (on a
different VT or via SSH). This causes the dialogue to be cancelled by
polkitd.

When gnome-shell receives the signal of 'set-content-type' from ibus,
gnome-shell calls KeyboardManager.holdKeyboard() and
KeyboardManager.releaseKeyboard() and the functions change the current
input focus in GNOME Xorg and it could result in closing a popup window
which has a password entry by focusing on the entry.
The solution is to stop to call the APIs on 'set-content-type' signal.

This is the last remaining usage of Shell.GenericContainer
in the codebase, and posed small challenges compared to the
other removals.
A new St.Widget subclass called InputSourceIndicatorContainer
was added as a replacement to the Shell.GenericContainer. It
was needed because GNOME Shell needs to override the regular
size allocation functions, but InputSourceIndicator already
is a St.Widget with its own size allocation overrides.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
In the process of purging all usages of Shell.GenericContainer
of GNOME Shell, one specific problematic situation that might
occur is when classes have functions that would clash with any
ClutterActor or StWidget function name.
One of such example is SwitcherPopup.destroy(). Right now, this
class is a pure JavaScript class that wraps a real actor, but
soon this will change, and it'll become a St.Widget subclass.
Another problem with functions that mimic the toolkit ones is
the predictability of them; after calling destroy(), that widget
is expected to not be available anymore. In SwitcherPopup case,
it is still available for a short while. In this case, that's not
a big problem, but the show() and hide() functions in other clases
are more problematic because the actor's visibility does not
follow that.
This commit is a first step in cleaning that up, and changes the
SwitcherPopup.destroy() to fadeAndDestroy().

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

imports.misc.ibusManager.IBus is declared as const, so referencing it
from another module triggers a warning with recent mozjs. As of commit
083d11a032 IBus is mandatory, so just make it a regular import to avoid
the warning.
Currently the language options displayed pretty much mirror those of the
top bar keyboard layout selection popup. It may make sense in the future
to only list languages, and automatically switch to the enabled IMs that
the OSK can benefit from (eg. by filling in suggestions).
In the current code it could happen that we've menuItems and indicatorLabels
for sources that aren't anymore around, because in case a source is removed
we don't cleanup the their container objects.
Also, we should nullify InputManager's _currentSource when sources change
or it might point to some invalid data again.
So it could happen that we try to access an invalid menuitem or label
if a source change happens mentioning a source that has been deleted.
