1. Updated the security mode of the print spooler. Now the spooler
is not signed with the system key, it is not a privileged app so if
it gets compromised (PDF rendering is a potential attack vector)
it cannot access dangerous permissions. Also only the system
can bind to the spooler.
2. Added APIs for asking a print service to start and stop tracking
a given printer. This is need for the case when the user selects
the printer and the print service should do a best effort to keep
the system updated for the current state of the printer.
3. Added APIs for putting a print job in a blocked state. A print
service would report the print job as blocked if for some reason
the printer cannot proceed, e.g. 99 pages are printed but there
is no paper for the last one. The user has to add more paper
and the print service can resume the job.
4. Changed the read/write APIs to use ParcelFileDescriptor instead
of FileDescriptor since the latter does not have a clean API for
detaching the wrapped Linux file descriptor when one wants to
push it to native.
5. Added API for getting the size of the printed document so the
print service can avoid handling big filed over cellular network
or ask the user if needed.
6. Now the print services that are preinstalled on the system image
are automatically enabled.

Using a contract class requires that a provider implement it exactly
with little help. This change introduces a DocumentsProvider abstract
class that provides a client-side implementation of the contract that
greatly reduces developer burden, and improves correctness.
This also moves to first-class DocumentRoot objects, and moves calls
with complex side effects to be ContentProvider.call() invocations,
offering more granular permission control over Uri operations that
shouldn't be available through Uri grants.
This new design also relaxes the requirement that root information be
burned into every Uri. Migrate ExternalDocumentsProvider and
DocumentsUI to adopt new API.

Even if the bars are transparent / invisible.
Refactor the PSB bar mode override logic to take the IME hint into
account. Bars are overriden to opaque when hint is showing.
Initialize bar state to showing, fix bug that would mark state
as hidden pre-show (on shell restart).
