8431e7ae51 misc/objectManager: Fix emission of object-removed signal
Emitting this signal is broken right now: We check for a length of 0 on
this._objects[objectPath], but the
`this._objects[objectPath][interfaceName] = null` we do before the
check doesn't actually remove the key, it only sets the value to null,
leaving the key around and thus the amount of entries in the object doesn't
change.

Fix that by using the delete statement instead, "delete" properly removes
the key and thus affects the amount of entries in the object, making our
length === 0 check effective.

9a814798d7 quickSettings: Fix icon-name construct property in menu toggles
Both :icon-name and :gicon are propagated to the internal QuickToggle
with property bindings. However the bindings are set up in the wrong
order:

:icon-name is a convenience property to set :gicon to a ThemedIcon
of the given name. That means binding :icon-name first will correctly
set the underlying StIcon's :gicon, but then the :gicon binding will
set it again to null.

Fix this by swapping the order in which the bindings are set up,
so that it works for both properties.

9e19f27e45 status/network: Generalize code to hide subtitle
Commit 9d75d777c7 introduced code to hide the subtitle of the
quick setting toggle when it matches the title of the toggle.
That's because NetworkManager tries to make the network names
more palatable on its own, and reports that the name of single
wired networks is "Wired" even if it may have another name.

What that commit failed to account for, however, is that there are
other circumstances where we end up with a subtitle is exactly the
same of the title. For example, when turning off Wi-Fi or mobile
broadband connections.

The behaviour of commit 9d75d777c7 is safe enough to be applied
on other device-backed connections, so do it.

ab0c795e81 status/location: Handle geoclue not being activatable
In GNOME OS, due to a misconfiguration, geoclue was configured without
systemd support. In that configuration, geoclue does not install its
systemd .service file (geoclue.service) but it (incorrectly) includes
the following line in its D-Bus service file:

    SystemdService=geoclue.service

As a result, when dbus-daemon tried to activate it at gnome-shell's
request, it would fail with:

    Unit geoclue.service not found

Then, GeoclueAgent._onGeoclueVanished() would be called, as the
name_vanished_handler passed to Gio.bus_watch_name(). This is consistent
with Gio.bus_watch_name()'s documentation:

> You are guaranteed that one of the handlers will be invoked after
> calling this function.

But that function assumed that this._managerProxy is defined, leading
to:

    JS ERROR: TypeError: this._managerProxy is undefined
    _onGeoclueVanished@resource:///org/gnome/shell/ui/status/location.js:163:9

Fix this by checking for nullishness of this._managerProxy. (Strictly
speaking, it's undefined rather than being null, but other code in this
file already uses the vaguer '!= null' test, which considers undefined
to be null.)

7a1b8f82e0 environment: Disallow all GDK backends
There is only a very limited subset of GTK that is usable from
within the compositor, and by now we should have replacements
for all of them in place.

On the other hands there is plenty that can go catastrophically
wrong in the rest. In particular on wayland, GTK must never open
a wayland display connection.

all GDK backends.

Prior to commit 7bd98f3f5f animation
onComplete handlers always occured at least after one main loop

656efd33af Update to drop GTK3 dependency
There's a few things going on here, that unfortunately must
happen in lockstep:

- The gnome-desktop-3.0 dependency gets replaced by gnome-desktop-4
  and gnome-bg-4. The code in ui/background.js required minor updates.
- The libnma dependency gets replaced by a libnma4 dependency. The
  code in misc/modemManager.js required minor updates.
- The gtk3 dependency is torn down everywhere but tests. Some
  missing GdkPixbuf dependencies had to be added to compensate for
  its lack.
- gtk_init_check() is no longer called

As a result, we replace a hard gtk3 dependency with a soft gtk4
run-time linking one, only added indirectly through gnome-bg-4
and libnma4.

feb1c57dde status/network: Fix WirelessNetwork related leaks
NetworkManager frequently refreshes the list of available access points.
For some reason this often ends up removing some or all access points
only to add them back in a later refresh later. With the exception of
the currently connected access point, which is never removed.

When all access points of a WirelessNetwork have been removed, it gets
destroyed by NMWirelessDeviceItem::_removeAccessPoint(). This however
does not happen for the currently connected network due to the always
present access point. If this network now happens to consist of multiple
access points, the "unused" NMAccessPoints will get removed and added
in these refreshes, without the WirelessNetwork getting destroyed.

Whenever such an unused access point is added, due to the use of signal
tracking this leaks the NMAccessPoint and SignalTracker until the
WirelessNetwork is destroyed.

However when the NMWirelessDeviceItem is destroyed, for example due to
suspending, it stops tracking access point changes, ensuring that the
condition for the WirelessNetwork being destroyed can not occur anymore.

Even with just two access points, such as can be found in 2.4GHz+5GHz
home routers this issue leaks hundreds of NMAccessPoints and
SignalTrackers per day. As well as a small number of WirelessNetworks
which are also kept alive by the SignalTrackers.

To fix this disconnect from the access point when it gets removed and
destroy all remaining networks when the NMWirelessDeviceItem is
destroyed.

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.

a91b6439ba overview: Validate transitions of the shown state
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.
