8c43376ea8 First cut of the print notifications.
1. Added notifications for a queued print job, for a started print job,
       for ongoing canceling a print job, and for a failed print job. The
       notifications for queued and started state have a cancel action. The
       notification for failed print job has a cancel and a restart action.

    2. Propagating failure message from the print service to the notifications.

    3. PrintJobConfigActivity was not setting the initial value for the
       print job copies and was not updating the UI immediately after creation.

    4. Refactored PrintJobConfigActivity to avoid using the hack to avoid
       reaction for item selection change in a spinner for an event that
       happened before the callback was registered.

    5. Removed the label attribute from PrinterInfo and now PrinterId is
       composed of the printer name and the service component name. This
       is nice since for restarting print jobs we do not need to store
       information about the printer except the printer id which is
       already part of the PrintJobInfo's data. Also the printer name
       is not expected to change anyway.

    6. Allowing cancellation of a queued print job. Also no print job is
       cancelled without asking the managing print service to do that.
       Before we were immediately canceling print jobs in queued state
       but it was possible for a buggy print service to not set the
       print job state to started before starting to do expensive work
       that will not be canceled.

    7. PrintServiceInfo was throwing an exception the the meta-data
       XML for the print service was not well-formed which would crash
       the system process. Now we just ignore not well-formed meta-data.

    8. Removed unused permissions from the PrintSpooler's manifest.

55b409a97c Iteration of the print sub-system.
1. Added APIs for adding partially initialized PrintInfo objects
   enabling light-weight lookps for print serivces that want to
   populate the list of available printers without querying each
   of them for its capabilities. This includes APIs for the system
   to request from a print service to update certain printers.

2. Fixed a bug in PrinterId#equals().

3. Added equals and hasCode implementaion to PrinterInfo. Also
   the defaul in PrinterInfo are now an array instead of a
   SparseArray - cheaper.

4. Now PrintJobConfigActivity works with partially specified
   printers. Specifically, if such a printer is selected the
   activity is requesting from the print service to update
   the printer. We are currently not handling the timeout case.
   It also handles udpated pritners.

a00271533f 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.
