Can't wait to double the size of this list when these start using D-Bus
activation.
These were actually renamed in GNOME 3.12, but we couldn't do anything
about it before, and now we can.
It was assumed that BackgroundSource objects were always destroyed
on monitor changes because the BackgroundManager objects that hold
references were destroyed, but sequencing of updating of different
BackgroundManager objects meant that was not the case.
Properly update any cached Background objects held by the
BackgroundSource on a change to the monitor layout; in particular this
means updating animations in case they are multi-resolution.
All other submenus link to the corresponding settings, so we should
do the same for location - the privacy panel in this case, which now
sports a "Location Services" switch ...

This lets us considerably clean up the event flow here and change how
things are structured. It also makes sure that we never show "No
Results" -- search.js not being aware of the timeout means that it might
not think that any work was being done when we show the page.
Keep a flag depending on whether a provider is in-flight, and use that
to determine what status label to show.
This ensures that we only show "No Results" when we're done searching
and we're sure that all providers have returned results back to us.
The complexities of tracking these two things separately, with the
display on one half, and the searching on the other half, is difficult
to manage. Squash it all together.
It is quite weird to have those calls/signals using WindowClone as an
argument, it is neater to pass MetaWindows around, and have each user
deal with their own representations of these.

And use it to lookup the local WindowClone that applies. Otherwise,
WorkspaceThumbnail.WindowClone objects may be mistakenly set, which
are not usable interchangeably with Workspace.WindowClone ones. This
may lead to several misbehaviors as fields available in the second
object but not in the first one are accessed, some those undefined
values get used in math ops, which result in NaNs over the place.
Likewise, the similar functions in WorkspacesViewBase subclasses take
now MetaWindow arguments too.

Instead of calling out to gnome-settings-daemon we'll just implement
the switching logic ourselves and use mutter APIs that allow this
functionality to work both in X sessions and when we're a Wayland
compositor.
Switching IBus engines is done transparently as well just like g-s-d
used to do.

gnome-settings-daemon doesn't this for us anymore. Note that
ibus-daemon isn't DBus activatable but just spawning it is fine
because it does its own single instance management. The library
notifies us when it shows up and goes away through the connected and
disconnected signals.

We don't really need this step as a separate method since all
implementations are supposed to be created and shown immediately. This
also ensures that we have items to show in all subclasses.
