Also add ContentObserver#onChange(boolean, Collection, int, UserHandle) so
clients can know the corresponding UserHandle for the notification.
Bug: 203606981
Test: atest CtsContentTestCases and manual testing to verify the observer can get notifications for
all the users.

Starting in R, there is a new public API overload that delivers a
flags argument. Some apps may be relying on a previous hidden API
that delivered a userId argument, and this change is used to control
delivery of the new flags argument in its place.
There are dozens of these hidden API users are in the system UID,
either in the system process or the Settings app, so we hard-code
giving them the legacy behavior, since refactoring would be messy
between internal and AOSP branches.
Also adjust incoming and outgoing method signatures to use slightly
more flexible Collection<Uri>, which has handy methods like
contains() and isEmpty().

As part of MediaProvider becoming a Mainline module, some partners
need to understand more details about what triggered a Uri change
notification. This helps listening apps avoid making expensive and
race-condition-prone calls back into MediaProvider; typically when
they're only interested in insert and delete operations. This change
uses the existing "flags" argument to communicate the reason.
This change adds overloads to ContentObserver for listening apps to
receive these flags. In addition, we add overloads that deliver a
clustered set of multiple Uris together in a single Binder transaction
to improve overall efficiency. (This matches well with the existing
CR.notifyChange() API that we added earlier this year, since they
both work with Iterable<Uri>.)
Tests to verify that we only collapse Uris together when all other
method arguments are identical.

Existing annotations in libcore/ and frameworks/ will deleted after the migration. This also means that any java library that compiles @UnsupportedAppUsage requires a direct dependency on "unsupportedappusage" java_library.

[Cause of Defect]
In the ContentObserver callback procedure, the binder thread
has no sync mechanism with handler thread.
The ContentObserver#onChange method can get called after
ContentResolver#unregisterContentObserver called in the
very low probability.
Bug: https://issuetracker.google.com/issues/63154326
Test: manual - check https://github.com/nanjingdaqi/ContentObserverDemo

We keep per user settings for enabled print services which are
observed to update the print manager service state. We were listening
to all user changes but the handling code was not updating the state
of the user whose settings changed, rather the current user.
Added hidden APIs in content observer to know which user changed
and now the print manager serivce handles content changes for the
correct user.

Added a new method ContentObserver.onChange(boolean, Uri) that
receives the changed content Uri. This can help applications make
better decisions about how to interpret a change notification.

Improved the documentation a little bit.
Fixed a bug in ContentService wherein if a ContentObserver was
passed as an argument and its deliverSelfNotifications() method
returned true, then notifyChange would tell all observers that
the change was a self-change even though it was only a self-change
from the perspective of the provided observer.
Deprecated ContentObservable.notifyChange since it is never
used and in general it shouldn't be because we want the notification
to be posted to the handler.
