This (mistakenly) now only depends on signals triggered on Wayland
sessions. Hardcoding the XIM support on X11 sessions will make input
in some clients work again.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1690
Currently, a failure to start the Systemd unit `gsd-xsettings.target`
would be considered a failure to start Xwayland.
That means that if `gsd-xsettings.target` fails to start for whatever
reason, no X11 client can be used on Wayland.
However, XSettings is by no mean mandatory for X11 clients and many
legacy X11 clients do not implement XSettings. Those who do always have
a fallback path and therefore can still work without XSettings.
Make a failure to start the Systemd unit `gsd-xsettings.target` non
blocking for Xwayland, and just log a warning message.

Now that Xwayland startup is asynchronous, the function may be called
before X11 is available, resulting in a crash.
Fix this by only managing the tray immediately if we already have an
X11 display, and wait for it to be set up otherwise.
Likewise, unmanage the screen when X11 becomes unavailable.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2308
Since support for legacy status icons is implemented by extensions
nowadays, they need to undo the call to manage_screen() when they
are disabled.
Right now that means bypassing garbage collection with an explicit
call to run_dispose() on the Shell.TrayManager. That works, but is
rather ugly.
An explicit unmanage_screen() method is a nicer option, and will be
useful to us as well to deal with X11 going away (once Xwayland
crashes don't bring down the entire session).
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2308
NaTrayManager in particular is deeply tied to X11. We currently assume
that X11 support is always available, but that is already not true
anymore - Xwayland startup is now asynchronous.
It will be even less true once we handle Xwayland crashes gracefully.
Start addressing that by not creating the corresponding resources once
and assume they exist for the lifetime of Shell.TrayManager, but make
sure they exist when actually needed.

We ended up always showing the switch-user button on the lock screen,
as showing and hiding it with the prompt was too visually distracting.
But now that we have a fancy transition in place, we can easily extend
it to the switch-user button as well.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1029
We only call _updateSensitivity() to make elements sensitive, and
nothing ever touches the sensitivity of the switch-user button; so
just call the corresponding authPrompt method directly, which is the
only bit that has an actual effect.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1029
We do spawn gsd-xsettings, and watch its name before notifying on the
given task, so the mutter bits can proceed with X11 startup.
One notable change is that we only start gsd-xsettings, instead of the
generic gnome-session-x11-services target. We do so as we have to wait
on a dbus name to appear in order to deem the initialization done, and
making it all depend on gsd-xsettings seems tidier.
Less notably, we also use ::shutdown-xserver to shutdown the related
services. Its major benefit is that it'd allow us to ensure the olderly
shutdown of those services, but it's unused at the moment.

When a window is being resized by the compositor, with Wayland the
compositor first asks the window to change its size and emits the
"size-change" signal, and then emits the "size-changed" signal after
the window acknowledges the new size. To show a fancy resize animation,
gnome-shell creates a "screenshot" of the resizing window on the
"size-change" signal, and later animates that "screenshot" to the new
window size on the "size-changed" signal.
Now if a client is not responding to our requests asking it to change
its size, we get a "size-change" signal and start showing the
window-clone, but never a "size-changed" signal, animating and hiding
the clone again. This causes a so called "ghost window" that is shown
above everything else and never disappears again.
To fix that, start showing the window clone once we get the
"size-changed" signal instead of the "size-change" signal. This makes
sure the window actually updates its size and the clone is going to be
hidden again.

Creating a new GTimeZone for the local timezone can be quite expensive if
done repeatedly. It requires an open(), mmap(), and parsing of
/etc/localtime.
This patch was provided by Florian, and I've tested it as far back as
3.28.4 to ensure that we are really reducing the number of open() calls
on the compositor thread.

The g_file_replace_contents_async() API can potentially call fsync() from
the thread calling into it upon completion. This can have disasterous
effects when run from the compositor main thread such as complete stalls.
This is a followup to 86a00b6872 which
assumed (like the rest of us) that the fsync() would be performed on the
thread that was doing the I/O operations.
You can verify this with an strace -e fsync and cause terminal to display
a command completed notification (eg: from a backdrop window).
This also fixes a lifecycle bug for the variant, as
g_file_replace_contents_async() does not copy the data during the operation
as that is the responsibility of the caller. Instead, we just use a GBytes
variant and reference the variant there.

Sadly, xgettext's dealing with template strings is abysimal, so we
had to stop using them in files with translatable strings.
Make sure we don't accidentally sneak in template strings again(*)
and enforce that rule in a CI job.
(*) easy "mistake", considering how much nicer they are than
String.prototype.format()
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1016
Also known as "Piotr Drąg Bot".
We will soon make sure that files processed by xgettext don't use template
strings. To make that check as adequate as possible, ensure that no source
code files are missing from POTFILES.

The thumbnails actor `this._thumbnails` has already been destroyed when
calling `_destroyThumbnails()` from the `destroy` signal handler because
it is a child actor of the AppSwitcherPopup. So stop destroying the
thumbnails separately (fading them out inside a destroy handler wouldn't
make sense anyway).

The correct property for the scroll-direction with scrolling events is
`direction`, no `scroll_direction`. This fixes scrolling in the alt-tab
popup, which broke with the actorization changes.

When the switcherPopup was initiated successfully, we return true,
otherwise the WindowManager will try to destroy it. Since an early
release of the keystroke will also switch to another application and
close the switcher just fine, we should return true to indicate success
here.

Right now the index that gets selected on click and motion events is set
when connecting the event inside the addItem function. If items are
added or removed (for example when an application is closed by pressing
"q"), this index isn't valid anymore and has to be updated.
To fix this, use the items themselves instead of the index as arguments
for the event handlers and lookup the index of the item inside the event
handler.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/167
Set the accessible states of the switcherList items by calling a
function instead of manipulating class-internal variables from outside
the class, which is considered bad practice.
The check whether the item at `_selectedIndex` exists can also be
removed since we always select a new index after an item was removed
(i.e. an app was closed) and destroy the alt-tab switcher right away if
no more items exist (see `SwitcherPopup._itemRemovedHandler`).

Limit the minimum and maximum value to scroll to inside the box to 0 and
the upper limit, for some reason this was done right in _scrollToRight,
but not in _scrollToLeft.
This fixes the behavior of scrolling to the left: Before, scrolling one
item to the left moved the view to the first element of the list (this
can make the selected element invisible in large lists). Instead, scroll
one item to the left, just like scrolling to the right works.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/167
Make sure the index that's being scrolled to doesn't change while the
scrolling animation is running by using an argument instead of the
this._highlighed class scope variable.
This fixes wrongly shown arrows when selecting new elements faster than
the scrolling animation takes for one index. The check run to disable
the arrow might be checking against a newer index than the one at the
start of the animation which results in the arrow not getting hidden
even if no more scrolling is possible.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/167
Since this._highlighted is always set to the currently highlighted
index, there's no need to save the index to a separate variable. This
obviously depends on getting the new item highlighted as a result of the
item-entered event.
This fixes bugs in situations where the highlighted element changes
after an event that is not calling _onItemEnter, for example after
scrolling or pressing a key. In those cases the _currentItemEntered
variable wouldn't be updated and the old item couldn't be entered
anymore without entering another one before.

Visually the button is just an interactive label, so having the
interactive area extend to the empty space next to the label
is surprising.
Instead, left-align the whole button rather than just the label
inside, so the clickable area corresponds to the visible one.

The 'gdm' user is not going to run a media player, so there is no
point in allowing the corresponding section on the login screen.
All other sections are already disabled, so this is the only reason why
we end up with the message list instead of only showing the calendar.
