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.

Updating the window list in the Looking Glass is a costly
operation: it destroys a whole lot of actors, and recreates
them. This triggers CSS changes, repaints, and allocations.
It is specially bad when paired with Wayland's big number
of window creations and deletions when showing Builder's
and Epiphany's popup window.
Only update the window list in the Looking Glass when it is
visible.

We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:
- they run entirely in C, while Tweener requires context switches
to JS each frame
- they are more reliable, as Tweener only detects when an animation
is overwritten with another Tween, while Clutter considers any
property change
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.

meta_later_add() is modelled after g_idle_add() and friends, and
the handler's boolean return value determines whether it should
be scheduled again or removed. There are some places where we omit
the return value, add them (although the implicit return value of
"undefined" already gives us the intended result).

Now that extension loading and the extensions map are no longer shared
between the gnome-shell and gnome-shell-extension-prefs processes, we
can move both into the ExtensionManager which makes much more sense
conceptually.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
The extension system started out as a set of simple functions, but
gained more state later, and even some hacks to emit signals without
having an object to emit them on.
There is no good reason for that weirdness, so rather than imitating an
object, wrap the existing system into a real ExtensionManager object.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
It makes sense to keep extension-related enums in the same module instead
of spreading them between ExtensionSystem and ExtensionUtils.
More importantly, this will make the type available to the extensions-prefs
tool (which runs in a different process and therefore only has access to
a limited set of modules).

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.

While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.
Spotted by eslint.

We are currently inconsistent on whether case labels share the same
indentation level as the corresponding switch statement or not. gjs
goes with the default of no additional indentation, so go along with
that.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
While allowed by the syntax, they are problematic because the
variable is in the scope of the switch() statement, but only
valid if a particular case clause is reached.
Add braces to limit the variables' scope to the corresponding
case clause to avoid that problem.
Spotted by eslint.

Converting a variable to a particular type can be done explicitly (with
functions like Number() or toString()) or implicitly by relying on type
coercion (like concatenating a variable to the empty string to force
a string, or multiplying it with 1 to force a number).
As those tend to be less readable and clear, they are best avoided. So
replace the cases of string coercion we use with template strings, and
clarify the places that can be confused with number coercion.

In order to replace GTK+'s GtkDirectionType. It's bit-compatible with it,
too. All callers have been updated to use it.
This is a purely accessory change in terms of X11 Display usage cleanup,
but helps see better what is left.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/361
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.
