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.

Currently when switching from a popup menu to another in the same
manager, we first show the new menu, then hide the old menu and
remove its grab, then create a new grab for the just shown menu.
This briefly ungrabbed moment will still trigger keyboard focus
changes, that might have other visible effects. In order to fix
this, change the grabbing order so first the new grab is created
then the old one is dismissed. This ensures focus moves from the
old menu to the new menu without gaps in between.
Since a grab is tied to an active menu, but close/grab are now
slightly decoupled, also ensure closing a menu only tears down its
own grab. This is necessary for correct accounting while doing the
grab shuffling.

Since the grab no longer lets events bubble up to the stage unstopped,
we should be forwarding the key events that bubbled up to the dialog
to maybe cycle focus.
Fixes broken keyboard navigation in several context menus around the
shell, other than the panel ones.

All callers have been updated to keep this handle to identify their
own grab.
Also, optionally use the windowing state to determine whether
the grab is suitable for the specific uses. This removes the need
to trying to grab twice in the places where we settle for a keyboard
grab.

With the presence of Clutter.grab(), this behaves differently enough
that needs some redoing. The larger difference is what actors are
eligible for handling events.
In the older code, a PopupMenuManager would ask the grabHelper to
capture events from all the stage, and selectively silence events
on any actor that is not the currently shown popup menu or the
"source" actor for any other popup in the group (i.e. those that
would pop up another menu).
But we don't want to just silence events, we want to emit the
correct set of crossing events when a popup menu is shown or closed,
this requires a backing ClutterGrab() on the currently shown menu.
Since the presence of a grab also affects the ability to have actors
outside the grab area to handle events, the PopupMenuManager now
must detect hovering and focus changes to other menu sources by
handling events on the grabbed popup itself.
Redo the grabbing over Main.pushModal/popModal (i.e. ClutterGrab,
plus keyboard focus restoration) and a captured event handler on
the currently shown menu, to make PopupMenuManager behave as it
is expected with this new kind of grabs.

If a menu item in a submenu is part of a section, it should have
rounded bottom corners if both the item and the section are the
last child of its respective parent.
To express that, add a new .popup-menu-section class and use that
to undo/redo the rounding for items inside a section.
It would be possible to do without a new class with a selector like
> StBoxLayout > .popup-menu-item:last-child:hover,
:last-child > .popup-menu-item:last-child:hover
but that's hardly better with its heavy reliance on implementation
details.

Since this is a bin and not a button, and it doesn't have any click/keyboard
handling on its own (as in that case it needs a parent button wired like in
the messages list controls), it is confusing that it has can_focus set to
True. To avoid any confusion, this commit removes it without breaking anything
since it had no real use.

While we do have some handling for removing the active menu, it has
been a no-op for years. The bit that we really care about from the
PopupMenuManager's point of view is the existing grab though. Drop
that instead of calling _closeMenu() directly; ungrabbing will still
call the method indirectly, and it will still be a no-op :-)

On Wayland, navigating menus with the keyboard would not open drop-down
menus when NumLock is enabled.
That's old issue (gnome-shell#550) that was not completely fixed with
commit 88556226 because the lock mask needs to be filtered out in
_onKeyPress() as well.

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.

Currently separators get all the padding from regular menu items,
which is excessive for non-interactive elements.
Shuffle style classes around a bit to allow overriding the normal
padding for separators.

Just like switcher popups, popup menus don't play well together with
system modals, and generally have a lower priority. So just like
switcher popups, close popup menus when a system modal dialog pops
up.

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).

Some vfuncs like `button_press_event`, `button_release_event` and
`touch_event` don't have handlers in the parent classes of
PopupBaseMenuItem. So don't call those handlers and return the default
Clutter.EVENT_PROPAGATE there.
This fixes a crash of the shell that happens when pressing a mouse
button inside the system popup menu and releasing it above a slider like
the volume slider again.

The PopupMenuManager is supposed to grab and focus the menu actors, with
normal menus we always need to grab the actual menu but set the key focus to
the source actor so that it will be able to move the focus to the menu
child, if requested.
However there are menus such as the RenameFolderMenu that requires the
key-focus once prompted, so provide a focusActor property (defaulting to the
sourceActor) that can be set in order to define the actor to give the
keyboard focus to, when the menu is popped-up.

The menu item ornament is used to put dots or checks in menus or otherwise
to define a padding for a label.
However in some cases we want to create a menu item with no left (in ltr)
padding.
In order to do that, define a HIDDEN Ornament mode that completely hides the
ornament actor.
The naming here might be confusing as this should probably be called NONE,
while the default mode is the invisible one, but it's too late to change it
now.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/725
We currently use no less than three different ways of indenting
object literals:
let obj1 = {
foo: 42,
bar: 23,
};
let obj2 = { foo: 42,
bar: 23 };
let obj3 = { foo: 42,
bar: 23
};
The first is the one we want to use everywhere eventually, while the
second is the most commonly used "legacy" style.
It is the third one that is most problematic, as it throws off eslint
fairly badly: It violates both the rule to have consistent line breaks
in braces as well as the indentation style of both regular and legacy
configurations.
Fortunately the third style was mostly used for tween parameters, so
is quite rare after the Tweener purge. Get rid of the remaining ones
to cut down on pre-existing eslint errors.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/716
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
When expanding a submenu, we currently use a single tween to animate
both the submenu actor and the source arrow. We do this by tweening
a monkey-patched JS property on the main actor, which we then use
to update the arrow's GObject property on updates. As Clutter cannot
animate random JS properties, this trick will prevent us from using
implicit animations here.
The only reason I can think of for using a single tween is to keep
both animations in perfect lock step, but as expansion and rotation
are visually quite distinct, this shouldn't be required, so just
set up separate animations for each actor.
