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 :-)

And set the dialog actor reactive. Specifically, we do not know whether
the parent actor is reactive or not, and we should not be changing that
from here, so do not use that actor to handle key events.

Using the callback directly as signal handler means that it will
receive the signal parameters (in this case: the StButton instance
that emits the signal).
This leaks an implementation detail that is harmless in the best
case, but can break dialogs when using bind() on the callback.
Avoid that trap by explicitly calling the callback without arguments.

As usually with GObject setters, we should check whether the property
actually changed before setting the value and notifying the property. So
check whether the title or description text actually changed before
setting it.
This fixes a bug which makes the title flicker and change its size,
because when updating the title we remove the "leightweight" css class
and reapply it inside a later, which makes the title appear larger for
one frame.

Since quite a few strings of dialogs provided by external programs are
not updated yet and the string freeze is already in effect, make sure we
don't break those dialogs by stripping aways large parts of the
headline.
To do that, detect if the title label is larger than the available width
and if it is, switch to a smaller font-size of 13pt. This makes sure we
still show about the same number of characters in the headline as we did
in previous releases.

`MessageDialogContent.messageBox` is not really needed and was only
needed to show icons, which is now no longer supported. The styling can
also be done using other CSS classes and this makes it a bit more
straightforward to add actors to the MessageDialogContent.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
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.

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).

Dialog's subtitle or body could not be properly wrapped, while it's ellipsized
when the text's width doesn't exceed the container size.
Clutter text has an `ellipsize` property, however in dialog's subtitle and body
we have been setting the `ellipsize-mode` property to Pango.EllipsizeMode.NONE
that is not present in the underlying GObject.
Not being an error in javascript, gjs didn't warn us about this, while at the
same time the St.Label's default Pango.EllipsizeMode.END was used.

Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)

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.

Since 0b02f757f8 we track the button that should have key focus
when the dialog is opened. However when the dialog is reused, the
button may get destroyed - clear the initial focus in that case to
allow setButton() to set a new one.
https://bugzilla.gnome.org/show_bug.cgi?id=788542
Commit 1c7a3ee61b broke setting the initial key focus for default
buttons added via addButton(). Fix this by allowing the dialog class
to provide a different default widget to ModalDialog than the entire
dialog itself.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

A lot of our modal dialogs share a similar structure:
[Icon] Some title
Maybe a subtitle
And sometimes even a body for stuff like
longer descriptions.
A dedicated widget with a common style will allow us to significantly
reduce duplication of both code and CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=784985
This is the basic dialog actor implementation, which will allow us to
use the same implementation on the session-global modal dialogs. The
ModalDialog class now uses it underneath, and so do all users of it.
