Dropping a icon from the dash to the application grid will set this._placeholder

In addition to the "overshoot/bumping into monitor edge" behavior we already
have, we also want to switch pages when simply hovering above the prev/next
page indicators.
This page switch shouldn't happen immediately though, it needs to be kicked
off using a timeout instead. The reason for that is that the next/prev page
indicators are large areas, and simply dragging there isn't enough of a
gesture to really interpret as "the user wants to switch pages".
After this page switch has been toggled once, it can be repeated using the
same "repeat" timeout we introduced with the last commit.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2581>
Right now we have a behavior in the appGrid where "bumping" the cursor
against the monitor edge during DND switches the page immediately, and
holding it there (at the monitor edge) switches pages again after a timeout.
With the next commit we'll introduce another way of switching pages during
DND, that is hovering over the next/prev page indicator to switch pages. To
allow those two methods to play well together, refactor the "overshoot" page
switching to make the timeout into a more generic "repeat" timeout. This
means we can now divide page switching can be roughly divided into two
different steps:
- Switch page immediately when bumping cursor against screen edge, also
works when repeatedly "bumping"
- Switch page automatically again after a second when keeping the cursor at
the screen edge without moving
We'll reuse the "repeat" timeout that's introduced here in the next commit,
where we'll introduce page switching by hovering the next/prev indicators.

With MR https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335,
the page navigation in the app grid was redone and prominent, always visible
navigation arrows were added. This larger change in the navigation of the
app grid also involved changes to the drag and drop behavior.
Before those changes (in GNOME 42), switching pages during DND in the app
grid worked like this: By "bumping" the cursor against the monitor/appGrid
edge, an immediate page switch would be triggered. Leaving the cursor in
that edge area would then trigger repeated page switches every second. By
repeating the "bump" gesture (moving cursor back into the grid, then
"bumping" against the edge again), it was possible to switch pages even
faster than every second.
When adding the always visible navigation arrows, we briefly tried out a
different way of page-switching during DND with commit 09b975fa: The "bump
against monitor edge" gesture (or "overshoot" behavior as it's called in the
code) was replaced with a hover timeout on the navigation arrows. The idea
behind that was to allow hovering the navigation arrow during DND to
eventually trigger a page switch, which also makes sense.
The replacement of the "overshoot" behavior made some people unhappy though,
so it was decided to bring back the old "overshoot" behavior with commit
4dcae8dd. Due to time pressure before the release that didn't go very well
and we ended up with a mixup of both approaches that doesn't feel too
polished.
So let's try to fix that by first going back to the working "overshoot"
implementation as it was in 42, then slightly refactoring that
implementation, to finally incorporate the new "page indicator hover"
behavior that https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335
originally intended to use.
This reverts commit 4dcae8ddd2.

If we are getting purpose hint changes while the language switcher is popped
up, this likely means the purpose hint was actually triggered by the key
focus change induced by the language switcher popping up.
In this case, we on one hand would like to preserve the state that applied
before thise focus change, and on the other we very much want to avoid the
keymap change that would forget about the keys being pressed.

The quick settings menu is child of an actor at 0,0 coordinates,
simply transformed to look in place. However the parent actor stays
at 0,0, and gets a width/height that is able to contain the child
menu (even though the transform will push it outside the parent
actor).
This makes the parent actor (not meant to handle pointer/touch
input) to cover parts of the shell. Since this actor is also where
the Clutter grab happens, the menu is not dismissed either.
Make this parent actor have a 0x0 size, so that it can still act
as the parent for the quick settings menu, but does not actually
cover any area. This makes clicks around the top left corner work
again while the quick settings menu is opened.

Some gstreamer plugins require a connection to the display server,
so they block until the server is up and running. That's why we
moved the check into the D-Bus service, so that the blocking would
not lock up the compositor itself.
However the block can still delay the service initialization so
much that auto-shutdown hits immediately when returning from the
constructor. If that happens, the proxy on the shell side is no
longer backed by a remote object when the init callback runs, and
all properties therefore resolve as `null`.
As a result, gnome-shell thinks that screencasts aren't supported
and hides the screencast button.
Fix this by holding the service during the gstreamer checks, so
that the auto-shutdown timeout only starts after the service is
ready.

The IBusInputContext currently seems to be a bit sloppy wrt propagating
the current state to engines after those are changed, this results in
engines possibly ending with purpose/hint/etc that do not actually
correspond to the current state.
Ensure this state is cleared on unfocus of our IBusInputContext, so
that the next time the input method receives an input focus, the new
state makes it all the way to the currently active engine.

would miss the PASSWORD hint set on the StEntry, and let passwords
be fed to engines.

Besides user interaction, there's two users of IBusManager.setEngine():
- The code that toggles all IBus engines off on entries with PASSWORD
purpose.
- The code that toggles completion support on OSK presence.
These are currently pretty oblivious to each other. Make this
interaction more resilient by making all external IBusManager changes
more cautious about directly changing the engine, and revoke properly
the completion mode if it needs be (e.g. changing to a non-XKB engine).
But another notable change is that ibus-typing-booster is now preferred
always, over PASSWORD purpose hints. This is done to avoid possible
doubled attempts to change the current engine (and ensuing IBusInputContext
confusion).

When propagating keys from the OSK, we usually feed these directly to
the IBusInputContext and let the IM handle the effects of this virtual
key event (which may also include feeding a key event back to us).
But these functions may also return a FALSE value if the key was "let
through" by the IM, which means the ball is in our yard again, and
we are responsible of letting this event get to its destination.
If that happens, just fall through, so the string is committed to
the client as an UTF-8 string, or propagated through keyboard events.

Consider the existing input sources MRU only valid if it contained
more than one element to pick from. Fixes the following situation
with initial-setup sessions:
- Initial setup Session starts, with several input sources already
configured ("us" between them)
- InputSourceManager initializes, only the default "us" keymap is
available
- MRU list is constructed, "us" is picked
- InputSourceManager catches up with session configuration, the
other extra sources are added
- MRU list is reconstructed, "us" is already the most recent
- Session ends up with "us" picked, regardless of its position in
the list, and no MRU existing prior to startup
If we consider the intermediate single-element MRU list invalid,
it is still possible to pick the best default source between all
the configured ones (the one that was put first in the list,
basically), after initialization is complete.
But also, it is unnecessary to have if there is a single source to
pick from. After the sources list has two elements or more, the
MRU list will become effective and preserved during changes to
the available sources.

Pipewire 0.3.52 via commit a1f33a99 introduced a change that affects how
long pipewiresrc holds onto the pw_buffers it dequeued. Before that
change the pw_buffer was held until the end of the videoconvert element
at the beginning of the pipeline. After that change the pw_buffer was
held onto until the filesink at the end of the pipeline. This was
starving MetaScreenCastStreamSrc of pw_buffers to record new frames
into, resulting in the majority of frames being missed, especially in
situations in which the encoder was taking longer.
Pipewire 0.3.57 via commit 1ea1d525 will allow queuing the pw_buffer
early again via the `always-copy` option. This however is only a
workaround until a proper solution is found in either pipewire or
gstreamer that does not depend on copying the buffer contents and
instead queues the pw_buffer again after videoconvert as prior to
a1f33a99.
Since it is not clear yet when a proper solution will arrive, this makes
use of `always-copy` as a workaround for now and should be reverted once
it is no longer needed.

The object the SignalTracker belongs to is stored in a map managed by
the SignalManager which keeps a reference to that object. This map is
never destroyed nor is any entry ever removed. This leads to all objects
that ever had SignalTrackers used on them being kept alive even after
all references outside of the SignalTracker are long gone. This then
also extends to other objects which are leaked indirectly through
reference chains from these objects.
And if some of those objects are GObjects, this will prevent them from
being finalized, leaking further resources. A StWidget for example will
not release its shadow textures.
Fix this by destroying the SignalTracker and removing it from the
SignalManager once the last signal it was tracking has been untracked.
A WeakMap could have been used as well, but we need the Map to be
iterable in some of the following changes.
