Another trivial cleanup. This is in preparation for next commit, that
will expand on this if clause, and will make it a bit more complicated.
Using a variable here makes it easier to read.

Often, when using multiple monitors, the thumbnails box may be
destroyed before the 'hidden' signal of the Overview is emitted,
which leaves a bunch of lingering signal connections to the
workspace manager.
Call this._destroyThumbnails() in the _onDestroy handler, which
disconnects from workspace manager. This fixes the some of the log
spam that GNOME Shell produces with backtraces of destroyed actors.

app_notify_events_added uses an intermediate builder to construct an
array that is then added to the main variant using g_variant_builder_add
which should clear the intermediate, but doesn't due to the way it is
passed: by value, rather than as a pointer.
This was debugged with the help of Eduardo Habkost, who believes it
works on x86 due to big structs being passed as pointers.

On systems/setups not using systemd, a failure to start gsd-xsettings
with NOT_SUPPORTED does not denote a failure to start Xwayland, just
that we're not using systemd.
In that case, we should just ignore the error, otherwise it will prevent
Xwayland to start on such systems/setups without systemd.
Thanks to Rose Kunkel (@rosekunkel) for spotting the issue/suggesting
the fix.

Currently, handling of touch devices in the app grid is a bit awkward,
paging by dragging the view can only happen if started from the gaps
between icons, trying to drag from an icon will trigger DnD, and popping
up the menu takes over it all.
Instead, have the app grid actions play this game of rock-paper-scissors:
- Fast swipes on icons trigger scrolling, beats DnD and menu
- Slower press-and-drag on icons trigger DnD, beats scrolling and menu
- Long press triggers menu, beats scrolling, is beaten by DnD
This allows quick swipes to handle navigation, while still allowing the
fine grained operations. DnD, when triggered, dismisses the menu, if
shown.
This all could probably be nicer with a more stateful gesture framework,
we're not there yet though.

This setting (by default, 0) sets a time threshold in order to allow
DnD. If the drag is shorter than this threshold, DnD will be cancelled,

We do notify on the ::pressed property after touch begin/end and
recording the event sequence, but we do not return the correct value
if the button was triggered via touch.
Consider the event sequence also in the ::pressed getter, so the
button is considered pressed.

The switcherPopups use _next() and _previous() to get the items
in the text direction. I. e. with LTR _next() gets the right item;
on RTL it gets the left item. This doesn't work well with RTL when using
the arrow keys since the text direction doesn't matter in those cases.
Pressing Left Arrow should still move left regardless of text direction.
So use the opposite methods.

If for some reason the xserver failed to start, mutter/gnome-shell
should not attempt to connect to the X11 display otherwise it will
lock up in XCB.
An indication of such a premature failure of the xserver is when the X11
services fail to start.
Return the status so that the caller can cancel the connection in time
and avoid the lockup of mutter/gnome-shell in case of failure.
This, however, makes the X11 services a critical component to start
Xwayland, meaning that a failure to start those services for any other
reason than the xserver failing to start would still prevent Xwayland
and therefore X11 clients to run in Wayland. This is however a lesser
issue than mutter/gnome-shell locking up.
This basically reverts commit a96753f0 - "windowManager: X11 can work
without gsd-xsettings".

Since commit f60a469a34, everything outside the fade area is painted
fully transparent. That is required for the fade effect during app
grid navigation, to prevent unfaded parts of surrounding pages
becoming visible on wide-screen displays.
However in most other cases, that behavior is the exact opposite
of what we want: Elements outside the fade area (like scroll bars)
should never fade.
In order to fix the regular case, hide the new behavior behind a
property.

Previously the workarea was only set on construction and then never
updated. As a result the preferred width and height as well as the
allocation were based on an outdated workarea size when it changed after
construction. This for example was happening during the startup
animation, for which the WorkspaceLayout is constructed before the panel
is shown. This caused the workspace in the overview to be slightly
smaller when it is first shown and the overview closing animation to
not expand the workspace to the correct size the first time it is
closed.

In the nested session the startup animation sometimes fails, weirdly
that always happens to me when running a freshly built gnome-shell the
first time. The reason it fails is that mutter fails to aquire a pointer
grab from the xserver, XIGrabDevice() is unsuccessful.
A simple workaround for this race condition in the xserver is to just
grab the devices a bit later, that is after the startups animation
instead of before it.
This was also tested with disabled animations, and seems to work just as
well in that case.

Some drag actor parents might change their width to 0 after the drag
actor has been removed. If the drag is now canceled and the drag actor
is animated to return to the current parent position and scale, this
scale can not be determined and falls back to 1.0. This might be wrong
and can result in the drag actor being too large/small at the end of the
return animation.
To avoid this calculate the scale of the parent by recursively
calculating the product of its parents individual scales.

Now that we made window previews overlap the edges of the wallpaper
underneath them, the app icons of those windows are getting quite close
to the dash and there is almost no more spacing.
Let's make it look a little bit better and slightly increase the
margin-top of the dash so that the workspaces move a few more pixels
away from the dash.

We want to clip the Workspace actor in the appGrid state of the overview
in order to make sure windows that overflow the monitor don't spill out.
So far we had commit b1970b95b8 for that.
Now since the last commit, window previews always slightly overflow the
allocation with their icons. That means a part of the window icon gets
clipped away as soon as the transition to the appGrid starts, which
looks weird.
Fix that bug in the transition by slightly extending the clip downwards
when animating between the window picker and the app grid state. The
extra height we extend the clip by is controlled by the overviewState,
which means we extend the clip by the full icon overlap in the window
picker state, but don't extend the clip at all when in the app grid
state.

We want to use as much space as possible for showing window previews in
the overview, and the title and close buttons of those windows are only
visible on hover, so we can show them above anything if we want.
On both primary monitors and secondary monitors, there's a certain free
space available towards the bottom edge of the monitor (on the primary
monitor we show the dash there, and secondary monitors just scale down
the Workspaces). We can make use of this by checking how much free space
there is available from the bottom edge of our allocation to the bottom
edge of the monitor, and then aligning the window previews to make full
use of this space.
So stop adding any padding to the edges of the Workspace, which will
make the windows a lot larger and completely fill the Workspaces
allocation.
The left, top and right monitor edges should always be far enough away
to accomodate the close button and hover scale-up of the window. Only
with the bottom edge of the monitor we have to be a bit more careful
(the overflowing height of the window title is quite big), so there we
check if enough free space is available. If there isn't enough free
space, we simply apply a bit of bottom padding again and shift the
window up.

Make the SecondaryMonitorDisplay a bit more similar to the
ControlsManager container on the primary monitor, and clip that widget
instead of the WorkspacesViews on secondary monitors.
This will allow us to overpaint the WorkspacesView allocation and paint
the WindowPreview overlays like the title and close button outside the
allocation with the next commit.

The current gstreamer pipeline performs quite bad on slower machines and
is dropping lots of frames, improve the pipeline by changing a few
things:
- Use threads for videoconvert and improve speed of videoconvert by
disabling some unneeded things
- Add a queue before the encoding step, this allows the encoder to work
at its own pace and will lead to a lot more stability
- Remove the fixed quantizer and only set a max quantizer, this helps
quite a bit with performance
- Change the deadline parameter of vp8enc to 1: This makes the encoder
go into real time mode, which will make it a lot faster
- Set cpu-used to 16, the maximum possible value.
- Set static-threshold to 1000, static-threshold is the motion detection
threshold, and while a value of 100 is recommended for screencasting in
the gstreamer documentation (see [1]), using 1000 appears to perform a
lot better and still outputs fairly good quality
- Set a larger buffer size than the default size, this seems to get a
bit more stability during high load scenarios
All in all, those changes make the pipeline drop no more frames when
recording at 30 FPS and 2K screen resolution. That was tested on a
fairly recent mobile core-i5 processor.
Also, because we now have two %T replacement strings for the number of
threads, we need to switch to replaceAll(). For that to work, we have to
put the %T matching expression into quotes.

The original parent of a dragged actor might have been destroyed after
the drag has been started. When the drag is canceled and _dragOrigParent
is set, the code is trying to get the current position and size of it
when restoring. With a destroyed parent this however would result in a
crash.
This could happen for example when starting a drag on a window preview
while the overview is hiding and then releasing it once the transition
is done.

`ThumbnailsBox` listens for the `showing` signal from the `Overview` to
create its thumbnails and destroys them on the `hide` signal. Since the
`showing` signal can be emitted multiple times when switching between
the shown and hidden state without ever fully completing the transition,
this will cause `_createThumbnails` to be called multiple times, each
time adding another set of workspaces.

When starting a gesture to open the overview while a transition to hide
the overview is running, Overview._shown will be first set to false when
starting the transition and then to true by the gesture before the
`onComplete` callback is called. The `onComplete` callback in this case
is `Overview._hideDone()` which starts a transition to show the overview
again which also emits the `showing` signal. Since the gesture emits a
`showing` signal as well, this results in two consecutive `showing`
signals without a `hiding` signal in between.
This breaks the `searchControler` which adds a key press handler to
start the search on `showing` and removes it on `hiding`. So every time
this happens a new handler that will never be removed is added,
resulting in the first key press being repeated.
