Fix BlobBackupHelper state tracking
The disk-friendly use of BufferedInputStream in state parsing was
actually breaking the state management system when multiple helpers
are involved in backup. The BufferedInputStream would blithely
pre-fetch 8K from the state file -- but that would consume some
state data that the dispatcher and subsequent helpers needed to see
in order to properly evaluate prior state themselves. The contract
here is that when using the helper mechanism, state-data consumption
must *only* consume as much data as the helper originally stored
into the file.
Switching to a direct-read stream instead fixes the problem by
avoiding read overrun. The rest of the changes are expanded
debugging output that made diagnosis possible.

Compress the preferred-app backup payloads
They can be Very Very Large, so take advantage of the new BlobBackupHelper
infrastructure to keep them tiny!
Also fix an issue in which the restore path wasn't properly passing
notification payloads along for processing, and an issue in which the
blob helper wasn't handling empty states properly.

Infrastructure for notification backup/restore
Introduce a fairly general "store byte[] blobs as backup keys" helper, and
use that to integrate with the Notification Manager. The helper provides all
the machinery of managing prior state, compressing the blob on the wire, etc.
