The existing app menu was a kludge of legacy code that tried to manage
a bunch of state, and had a number of issues:
* It didn't properly manage visibility when combined with multiple
apps and the overview.
* It didn't properly manage reactivity when tabbing away from a busy
app to another app.
* It didn't properly disconnect signals when going from one app
to nothing.
and countless others. Rewrite it to use the new "sync" code pattern,
where we centralize all state management and do transitions from that,
rather than strange and quirky control flow.

Make the lock dialog group reactive, to intercept any events
before they go to the actors below.
In the future, we may restructure our chrome to have a clear
layer system, but for now it fixes a security issue in the lock
screen (you can see the contents of the windows by dragging
if the screen was locked with the overview active)

There's only two uses of the parameter left, which can easily be added as a
separate line below. Since it's really a private interface meant for the
indicators, make it private as well so external users are less likely to
use it.

To align the arrows, we need to allocate panel buttons the full
height of the tray. Fix up all of the panel buttons to support this,
and align the arrows in the middle.

Swap out the implementation of SystemIndicator with a dummy,
and build the aggregate menu. At the same time, remove the
poweroff and login screen menus, as those were fake aggregate
menus beforehand.
We lose some flexibility as we lose session-mode-based menu
layout, but as each component of the aggregate menu is supposed
to be "smart" in response to updating itself when session
state changes, I believe it's better than a declarative model.

We can't silently replace the old behavior of separate status
icons into a new system. Replace SystemStatusButton with a new
SystemIndicator class which will allow for the flexibility we
need. For now, make it a subclass of Button so that it mostly
feels the same, but we'll soon be swapping it out with a dummy
implementation that the aggregate menu will use.
I think the code cleanup here is worth it.

This code is too complicated to keep, and the last straw came after the
fixed width menu in the aggregate menu design.
This will break some existing popup menus that rely on the fixed width,
but this will soon be replaced with the aggregate menu. We'll also soon
clean this up further by replacing PopupBaseMenuItem's custom layout code
with an StBoxLayout.

Showing the new message at full size marks an abrubt change and looks
bad. Instead, gradually animate from 0px to full natural height.
Includes hacks to workaround flickering scrollbars while the animation
is in progress.

If that fails (which only ever happens in initial-setup mode, which
has no unlock or login dialog), we don't want to go ahead with
whatever we were doing.

If we don't remove the animation, we might leave a pending call
to _lockScreenShown() which would confuse our state tracking into
thinking we're active when we're not.

Using a signal handlers causes us to depend on connection order, but
we need the message tray code to run last, so it can notice that
notifications are destroyed when hiding the boxpointer and skip
the broken animation.
