Also extend API to accept a "count" argument of exactly how many
bytes to copy, and return the actual number of copied bytes.
Improve docs.

1. Removed an unused public constant
2. Hide PrintFileDocumentAdapter which makes doing the wring
thing easy.
3. We allow a print service to set a tag of a print job which is
an arbitrary string it only knows how to interpret. Typically,
this is the id of a remote print job. This tag was visible to
applications which is wrong - this is data that should be
private to the print service. Now the print service is the
only one to see that.

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.

1. Factored out the printer discovery APIs of a print service in a
dedicated session object that is created by the print service on
demand. This ensures that added/removed/updated printers from
one session do not interfere with another session.
2. Updated the app facing APIs to pass in a document info along
with a printed file. Also exposed the print file adapter so
apps that create a temporary file for printing can intercept
when it is read by the system so the file can be deleted.
3. Updated the print service documentation.
