Update the PrintDocumentAdapter docs.
This change adds some clarification when a cancellation will be
requested during a layout or write. It also clarifies from which
thread the layout and write callbacks can be invoked.

Handle print serivce crashes.
1. Now after a print service crashes we are bringing it to the same
state of its lifecycle. For example, if a service does a discovery
and crashes we recreate the discovery session call the start
discovery method and so on.
2. Turned off debugging logs since we have fully fledged state dump.

Print API updated.
1. Removed the updatePrinters API on PrinterDiscoverySession.
Now re-adding a printer updates it.
2. Added getTrackedPrinters() API to allow a print service to
figure out which printers' state should be tracked by the
service.
3. Removed the APIs on PrintDocumentInfo that describe the
layout of the content as they are not needed. For example,
if the print attributes passed in layout require landscape
mode, the the app should just create a PDF page with the
wider side up and draw its content in portrait. The printer
will then rotate the page.

Print spooler security and some new print service facing APIs.
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.

Print APIs update.
1. Added scale to fit and scale to fill fitting modes.
2. Added APIs for a print app to specify which constraints imposed
by the print attributes were satsified during a layout so they
are not handled by the printer again, e.g. if the content is to
be in landscape the the app generated such content the printer
should rotate the content again.
3. Added some printer statuses.
4. Added a helper class that generates PDF documents with correct
size based on the passed in print attributes.
5. Exposed a ctor for PageRange which was hidden by mistake and apps
could not create page ranges. Added API for changing the printer
status.

Iteration on the print sub-system.
1. API changes: Moved copies API from PrintAttributes to PrintJobInfo;
Changed the PageRange list to an array in PrintDocumentAdapter#onWrite;
Added onCancelled method to the layout and write callbacks.
2. Refactored the serialization of remote layout and write commands. Now
the commands are serialized by the code in the client instead in the spooler.
The benefit is simple code since the client has to do a serialization to delegate
to the main thread anyway. The increased IPC found is fine since these calls
are quite unfrequent.
3. Removed an unused file: IPrintSpoolerObserver.aidl
4. Added equals and hasCode implementation to PageRange, PrintAttributes,
MediaSize, Resolution, Margins, Tray, PrintDocumentInfo.
5. Added shortcut path for query APIs on PrintJob that return cached values
if the print job is in a uncuttable state, i.e. completed or cancelled. Failed
print jobs can be restarted.
6. PrintJobInfo was not properly serialized.
7. Updated the look of the print dialog to be stable if there is and there isn't
currently selected printer.
8. PrintJobCOnfigActivity now calls onLayout on every print attributes change
but requests a write only on print preview or print button press. Also if the
layout did not change the content and it is already written no subsequent
call is made. Also if the selected pages change and we already have them
no subsequent call to write is made. Also the app is called with print preview
attribute set when performing layout and with it cleared after the print button
is pressed. A lot of changes making sure that only valid actions are enabled
in the activity (looks like a dialog) at a given time frame. The print job config
activity is also hidden after we got all the data, i.e. layout and write are done.
9. The callback from the print spooler to the system are scheduled via messages
to avoid lock being held during the call. It was hard to guarantee that since a
method holding a lock may be calling one that would like to release the lock
at some point to make the callbacks.
10. Print spooler state is persisted only if something changes in a completed
print job, i.e. not one that is being constructed due the print job config dialog.
11. Fixed a potential race in the RemotePrintSpooler where it was possible that
a client that got a handle to the remote spooler calls into an unbound spooler.
E.g: the client gets the remote interface with a lock held, now the client releases
the lock to avoid IPC with a lock, during the IPC scheduling the spooler has
notified the system that it is done and the system unbinds from it, now the
client's IPC is made to a spooler that is disconnected.

Tweak the print APIs.
1. Adding bundle with metadata to PrintDocumentAdapter#onLayout
with one key for now to specify whether this is for a preview.
2. Cleaned up docs.

Refactoring of the print sub-system and API clean up.
1. Now a user state has ins own spooler since the spooler app is
running per user. The user state registers an observer for the state
of the spooler to get information needed to orchestrate unbinding
from print serivces that have no work and eventually unbinding from
the spooler when all no service has any work.
2. Abstracted a remote print service from the perspective of the system
in a class that is transparently managing binding and unbinding to
the remote instance.
3. Abstracted the remote print spooler to transparently manage binding
and unbinding to the remote instance when there is work and when
there is no work, respectively.
4. Cleaned up the print document adapter (ex-PrintAdapter) APIs to
enable implementing the all callbacks on a thread of choice. If
the document is really small, using the main thread makes sense.
Now if an app that does not need the UI state to layout the printed
content, it can schedule all the work for allocating resources, laying
out, writing, and releasing resources on a dedicated thread.
5. Added info class for the printed document that is now propagated
the the print services. A print service gets an instance of a
new document class that encapsulates the document info and a method
to access the document's data.
6. Added APIs for describing the type of a document to the new document
info class. This allows a print service to do smarts based on the
doc type. For now we have only photo and document types.
7. Renamed the systemReady method for system services that implement
it with different semantics to systemRunning. Such methods assume
the the service can run third-party code which is not the same as
systemReady.
8. Cleaned up the print job configuration activity.
9. Sigh... code clean up here and there. Factoring out classes to
improve readability.
