Updates to progress bars are the main culprit in system
performance events caused by apps spamming the notification
service. Rate-limiting only updates allows us to set a lower
threshold wihtout the owrry of mistakenly dropping bursts of
notifications being quickly posted after a network sync.
Also reduce logspam caused by the rate-limit events.

- When the cached UID state says a UID is in the background,
check with AM and get the latest state, since the state
might just have been changed.

A lot of calling framework code expects a null value on failure,
and didn't catch the previous exception. There were some strange
corner cases where previously a null value was not checked for
in framework code, allowing the null Resources object to be
returned to the caller. Introducing an exception changed the
semantics and can crash certain apps.

Remove lock contention when unlocking users
Only get trace name if tracing is enabled
Fix multi-window drag jank if vsync-app is before vsync-sf
Prior to N, our widgets were not converting MarginLayoutParams
properly between ViewGroups. The fix intrudced some issues in
older apps as the broken conversion code would hide developer
errors. This CL guards the change with a target API check so
that we don't affect older apps.

Someday maybe the technology will exist to
allow sharing a simple constant between
Java and C++, but today is not that day.

Changes in alpha only matter if they affect visibility,
so only 0 <-> nonzero changes are worth reporting. Report
them as subtree changes, as visibility affects subviews.
Not reporting every change greatly reduces the number of
event reported when alpha is animated.

Previously AbsSeekBar always rounded up, which resulted in poor handling
of touches near the edge of a progress value. We fixed this but forgot
to adjust RatingBar for the new behavior.

It was possible for apps to put toast type windows
that overlay other apps which toast winodws aren't
removed after a timeout.
Now for apps targeting SDK greater than N MR1 to add a
toast window one needs to have a special token. The token
is added by the notificatoion manager service only for
the lifetime of the shown toast and is then removed
including all windows associated with this token. This
prevents apps to add arbitrary toast windows.
Since legacy apps may rely on the ability to directly
add toasts we mitigate by allowing these apps to still
add such windows for unlimited duration if this app is
the currently focused one, i.e. the user interacts with
it then it can overlay itself, otherwise we make sure
these toast windows are removed after a timeout like
a toast would be.
We don't allow more that one toast window per UID being
added at a time which prevents 1) legacy apps to put the
same toast after a timeout to go around our new policy
of hiding toasts after a while; 2) modern apps to reuse
the passed token to add more than one window; Note that
the notification manager shows toasts one at a time.
