Switching between the app grid and the window picker in the overview via
gestures results in _gestureEnd() getting called with endProgress !== 0
in both cases, which leads to it calling _showDone(). This then
unconditionally changes the state to SHOWN, which in this situation is
already the current state. Since the previous commit this results in a
warning, so check if we are already in the SHOWN state.

(cherry picked from commit f5d793647b)
There have been several bugs in the past that caused invalid transitions
of the `shown` state, such as going from `showing` to `showing`. These
cause consecutive emissions of the `showing` signal, which can confuse
other classes such as the search controller which connects to the stage
`key-press-event` on showing and disconnects again on `hiding`. Having
two consecutive `showing` signals will cause it to connect twice, and
only disconnect once when hiding the overview again. This will lead to
key presses getting repeated in the search until the session is
restarted. Because there is no obvious connection to how and when this
issue got triggered, this now adds some validation code that only allows
valid transitions and throws an error otherwise so we get a backtrace of
the code actually causing the problem.
This does not fix the issue(s) causing the invalid state transitions, it
only adds a way of tracking them down.

Dropping a icon from the dash to the application grid will set this._placeholder
to null. However the AppIcon is still used to represent the application in the
application grid. If we click on it we emit a pressed event. Stop assuming
that this._placeholder is still valid in the callback, use the icon parameter
instead.
This fixes the following error:

When GNOME shell runs on a less memory system (for example 3 GB RAM), it
is usually killed by the kernel OOM-killer easily. Because, it has a
higher OOM score. However, GNOME desktop environment cannot do anything
when the GNOME shell is killed.
This commit adjusts and lowers down gnome-shell process' OOM score to
avoid being killed by the kernel OOM-killer too early. In other words,
sacrifices other processes first.

(cherry picked from commit 09c8fb5414)
When gjs overhauled its coding style, it opted for disallowing
spaces around braces in object literals: `{foo: 42}`.
We opted out of that particular rule in commit 09b8e8f, primarily
because it would have been a very intrusive change with the old
style of object literals:
```js
let oldStyle = { foo: 42,
bar: 23 };
```
Alas, all multi-line object literals have been transitioned to
the new style where braces go on separate lines, so they are no
longer subject to the rule one way or the other.
Nowadays the rule mostly affects destructuring, and there it
is a bit odd to apply different spacing rules to arrays and
objects:
```js
const [foo, bar] = someArray;
const { baz, quz } = someObject;
```
This is now the main divergence from the canonical gnome style,
and the only one where we directly contradict it.
It would be good to transition away from that, and as the rule
now only affect destructuring and single-line object literals,
we can do that on a case-by-case bases by moving the override
to the legacy configuration.
As desctructuring imports makes up a fair share of the affected
code, and those will change when moving to ES6 modules, this
seems like a good moment to start that transition.

Since commit 7bd98f3f5f the onComplete callback
is called right away when animations are disabled. As side effect, now
this._coverPane gets shown/hidden in the wrong order. Start the animation after
setting this._coverPane initial state, so that the animation callback can set the
this._coverPane final state without it being overwritten later.
Move the animation also after emitting the showing and hiding signals. So that the
order showing -> shown and hiding -> hidden is still preserved when animations are
disabled.

When the overview is hidden just after starting GNOME Shell the app

(cherry picked from commit 2326721561)
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.

When updating the MRU sources if there was no prior MRU, we want
to go with the unmodified list of sources in visibility order.
However iterating over object properties happens in an undetermined
order, so the initial MRU list ends up picking a value at random.
In order to prefer the sources list in the same order than they
appear in the menu if there was no prior MRU, order the keys
when accessing it and building the initial list of 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.

(cherry picked from commit d32c03488f)
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.

After the next commit, when some classes, such as PopupMenuManager try
to disconnect via a destroy handler, the SignalTracker might have
already been destroyed, so trying to get it from the SignalManager will
cause it to create a new one, which will then try to connect to the
destroy signal of the already destroyed object.
This could for example be triggered by changing backgrounds.
Fix this by not doing anything in disconnectObject if there is no
SignalTracker for that object.
