If the background is already removed, or we're trying to remove bad content,
this is probably a bug in content accounting, so let us crash so we can fix
the bugs.

Stomping on local variables and trying to keep loop state isn't
too fun. Just use a new variable here so we aren't too confused
with what we're doing.

We don't have any better way of determining whether something is a slideshow
animation, so discriminate on the .xml filename instead of waiting for
gdk-pixbuf to determine whether it can load a file or not.

The destroy vfunc might be called during object finalization, and
we can't call any JS from a GC finalizer, so we use a signal
connection instead, as that is removed by GObject the first time
the object is disposed.

After a user types in their password at the login screen, one
of two things can happen
1) a new session is started
2) an existing session is switched to
In the latter case, GDM sends a reset signal to the login screen,
so it knows to go back to the user list and wait to be summoned
again.
Unfortunately, all reset signals are ignored after verification
success. The reason is because the reset handler was copied from
the unlock dialog as part of a deduplication effort in commit
7e7295f259 and the unlock dialog
handler at the time also emitted a "failed" signal on reset
(which wouldn't make sense to emit after success).
These days "failed" is handled in a different way.
This commit changes the code to let reset signals through after
successful verification.

AppDisplay queues a deferred work to load frequently used apps when the
apps page is loaded. Unfortunately, when the overview is first opened,
all the pages start out visible and then immediately get hidden, so the
deferred work runs immediately after the first overview opening, whether
the user was going to view their frequent apps or not.
Start all pages off as hidden, and rearrange the code so that pages are
only shown when they really need to be.

This is also exposed in the ShowOSD DBus method, the "monitor"
parameter may contain an integer to indicate the monitor number.
If the value is not provided or <0 is used, the monitor is shown
on the primary monitor as usually.
This way, the OSD can be used to notify upon events that solely
apply to one monitor, like tablet mapping as discussed in
https://bugzilla.gnome.org/show_bug.cgi?id=710373.

You would think we would already do something like this, but apparently
lots of code was calling hide() without checking if the box pointer was
already visible, causing it to queue a full tween. The biggest win was
with ibusCandidatePopup.js, which called hide() on every DBus message.
This increases the performance for me to enter the overview by a tiny
bit. The remaining time is spent updating the frequent apps / all apps
display.

The methods we call in _updateState may not be reentrant, so make
sure that we never get into a situation where _updateState, through
some crazy chain of events, calls itself.

Rather than scanning all apps for searching, use Ryan's new desktop
file index and the glib support APIs for app searching instead of our
own system.

If monitor-changed fires at startup, it will destroy all of the
backgrounds, but since this._isStartup is true, won't recreate any
of them. Additionally, since _bgManagers is indexed by monitor index,
if the primary index is not 0, it could become a sparse array (e.g.
[undefined, undefined, primaryBackground]), and our for loop will
crash trying to access properties of undefined.
Fix both of these issues by always creating background managers for
every monitor, hiding them on startup but only showing them after
the startup animation is complete.
One thing we need to watch out for is that while LayoutManager is
constructing, Main.uiGroup / Main.layoutManager will be undefined,
so addBackgroundMenu will fail. Fix this by passing down the uiGroup
to the background menu code.

If desktop icons are enabled and not covered by maximized windows,
we will fade them in/out during overview transitions. However when
moving background handling into mutter/gnome-shell, we ended up with
the overview background on top of the DESKTOP window clone, hiding
the fade transition.
Fix the stack order to bring the effect back.

Our gnome-shell tweener integration has had hooks to determine when
the tweens have started and completed... except that they had a bug
in them. When a tween completed, it queued an idle handler to run
the callback in. If no tweens were running when the idle was removing,
it reset the tween state that contained the idle handler ID. It also
returned false, meaning that the source would always get removed.
If the actor had a tween in-flight when the idle was fired, it wouldn't
clean up after itself. While this is also a simple bug fix, remove the
callback so we don't queue unnecessary, unused idles.

While unfortunate that we still have to scan all apps with get_all(),
support for this feature will be short-lived, so hopefully we can drop
it in the future as new apps adapt to the desktop file / app ID
recommendations.
For now, simply scan all desktop IDs.

Systemd-for-the-user-session would also do this, but that's a deeply
invasive change that I may not actually get to this cycle. This
change is tiny and non-invasive, but provides an important benefit:
You can actually reliably tell *which* applications are logging which
messages (assuming they're launched by the shell).
This actually complements a recent change in DBus:
See https://bugs.freedesktop.org/show_bug.cgi?id=68559
which does a similar thing for bus activated apps.
