`NMConnectionDevice._sync()` is responsible for setting up the active
connection that we'll end up displaying. It expects the active
connection to already be in a map `_connectionItems`. If it isn't in
there, we get a null dereference and the indicator can get into a weird
state where it doesn't display devices / connections properly.
Let's change this expectation. If there is an active connection,
`_deviceAdded()` will eventually get to it and call `_sync()` to set up
the active connection state. We make `_sync()` tolerate there being no
active connection when it's called.

We must remove the GFile reference from the representing object when an
extension has been unloaded as this won't be used anymore later (e.g. as cached
ref).
Throw an error using an informative message in case a mode uses a stylesheet
that can't be loaded, instead of crashing later because the theming can't be
properly computed, and thus the minimum size of the actors.
We currently assign the stylesheet to an extension whenever the file exists,
regardless of whether it actually loaded successfully or not.
And thus we load an extension that ships a stylesheet even if that file can't
be used.
There is no point in trying to load an extension if its stylesheet wasn't
loaded in the first place, so make sure this happens only on success.

Ensure that the search provider operations (just getResultMetas requests
in the current implementation) in progress are properly cancelled when we
clear the UI, otherwise returned results might still be added when not
needed.
This is triggered for each provider by the SearchResults reset.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/205
Currently when the overview is hidden, any pending search is kept alive,
not only at remote search provider level (as per issue #183), but even
the shell providers proxies continue to get and process data. This happens
even if this is not needed anymore, while the UI reset is performed only
next time that the overview is shown (causing some more computation
presentation time).
In order to stop this to happen, when the overview is hidden, we have to
unset the search entry to an empty value as this would make SearchResults
to have empty terms list and that would make the proxies cancellable to
be triggered (without causing any further search to start).

If the volume is removed before AUTORUN_EXPIRE_TIMEOUT_SECS seconds, we can stop
the timeout earlier as there's nothing to unset, while the volume instance
won't be valid anymore.

The _sync function for Message only updates the close button visibility,
so we can safely stop doing that if the close button get get destroyed earlier
(as it happens when clicking on it).

We need to avoid that we use the _dragActor instance after that it has
been destroyed or we'll get errors. We now set it to null when this
happens, protecting any access to that.
Add a DragState enum-like object to keep track of the state
instead of using booleans.
Remove duplicated handler on 'destroy' and just use a generic one.

The object manager tries to synthesize interface removal
events if the bus name of a remote object drops off the bus.
The code had bad typos in it, though: it reuses the `i`
index variable in its inner loop, where it should be using
the `j` index variable.
This commit corrects the i/j confusion.
The object manager tries to synthesize interface removal
events if the bus name of a remote object drops off the bus.
The code has a bad typo in it, though: it confuses `objectPaths`
(the list of all object paths) and `objectPath` (the object
currently being processed this iteration of the loop).
That leads to a failure to synthesize the interface removal
events, and spew in the log.
This commit corrects the objectPath/objectPaths confusion.
Previously mutter listened to Xsettings (via GTK) to get notified
whether the shell showed the app menu. After X11 support was changed in
the direction of being less central, listening to this particular
Xsettings were removed with the intention of having the Shell tell
mutter directly whether it was showing the menu or not.
This commit makes that happen. It still travels through Xsettings (still
via Gtk), as the shell still gets that state from Xsettings, but fixing
this is out of scope for this particular fix.

Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)
Also a couple of bugs are fixed by this:

Instead of consuming the event in front of the input method. Enter
is sometimes overriden by those, so it seems better to let the IM
handle the key event, and react later to it if it got propagated
anyway. That is what ::activate does, so use this signal.
This used to work before ClutterInputMethod/InputFocus because the
IM received the events directly from stage captured events. This
is not the case anymore.
Closes: #440
