Calling requestLayout() during a layout pass is inadvisable, but
happens often enough in applications (especially when it occurs in
very indirect means that the application may not easily be able to
control) that we need to handle the situation without breaking. In particular,
applications that have run across this problem have had artifacts which are
difficult to debug (like things just not showing up on the screen) and
also difficult to fix. One of the side-effects of the problem is that it
leaves the view hiearchy in an unpredictable state where some views have
requested layout and are waiting to be layed out while the root view has
not received those requests, so it is never calling layout on those views.
The fix is to try to do the 'right' thing, while avoiding getting into
an inifinite loop (which could result from calling layout, which calls requestLayout(),
which causes another layout, which ...). The solution is two-tier: we handle
all requests that happen during layout by delaying them until after the current
layout is done. We then process those requests and call layout again.
If we receive more requests during that second layout, we post them to the
next frame, to allow us to finish the current one.
Issue #7155974 handle requestLayout() during layout more robustly

Dream manager now fires broadcast intents when entering + exiting
dreamland (except when testing).
Power manager can now listen for dreams ending, using polling only
as a backstop.
Also:
- Bullet-proof dream-manager/dream against known failure modes
- Add new read/write dream permissions
- Refactor dream-manager to delegate work + state management into
a new DreamController class, via a handler

Notification and Alarm volumes are per user: they are saved and restored
when the foreground user changes.
Media volume is global: it is still saved and restored per user for
implentation reasons but is copied from one user to the next to ensure
media playback volume continuity when switching users.
Ringer mode (silent, vibrate...) is now a global setting.

This provides a mechanism for exposing the bells
and whistles we've attached to trust managers to
third parties.

- New "cost money" flag can be put on a permission to
have this emphasized in the UI.
- Some further re-organization of permissions to better
match UX spec.

- New public APIs to find out when a user goes to the foreground,
background, and is first initializing.
- New activity manager callback to be involved in the user switch
process, allowing other services to let it know when it is safe
to stop freezing the screen.
- Wallpaper service now implements this to handle its user switch,
telling the activity manager when it is done. (Currently this is
only handling the old wallpaper going away, we need a little more
work to correctly wait for the new wallpaper to get added.)
- Lock screen now implements the callback to do its user switch. It
also now locks itself when this happens, instead of relying on
some other entity making sure it is locked.
- Pre-boot broadcasts now go to all users.
- WallpaperManager now has an API to find out if a named wallpaper is
in use by any users.
