Revert "Backup/restore recents task list"
Reverts commits 92dd1abef4c0a22db40c5f7bbd100e6b471a1ad3,
18795a2299fefd88ee16393f22324b999ace6ce4, and
ac6a3a5e9d90edb533e5b377a4a14ef514be955a which make-up
changes required for backing-up and restoring recent
tasks from one device to another.
The implementation had too many unresolved issues including
the ordering of the restored recent tasks which was depending
on when the task package is installed on the new device that
puts the restored recents list out of order compared to the
old device.

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.

Add payload-size preflight stage to full transport backup
We now peform a total-size preflight pass before committing data to the
wire. This is to eliminate the large superfluous network traffic that
would otherwise happen if the transport enforces internal quotas: we
now instead ask the transport up front whether it's prepared to accept
a given payload size for the package.
From the app's perspective this preflight operation is indistinguishable
from a full-data backup pass. If the app has provided its own full-data
handling in a subclassed backup agent, their usual file-providing code
path will be executed. However, the files named for backup during this
pass are not opened and read; just measured for their total size. As
far as component lifecycles, this measurement pass is simply another
call to the agent, immediately after it is bound, with identical
timeout semantics to the existing full-data backup invocation.
Once the app's file set has been measured the preflight operation
invokes a new method on BackupTransport, called checkFullBackupSize().
This method is called after performFullBackup() (which applies any
overall whitelist/blacklist policy) but before any data is delivered
to the transport via sendBackupData(). The return code from
checkFullBackupSize() is similar to the other transport methods:
TRANSPORT_OK to permit the full backup to proceed; or
TRANSPORT_REJECT_PACKAGE to indicate that the requested payload is
unacceptable; or TRANSPORT_ERROR to report a more serious overall
transport-level problem that prevents a full-data backup operation
from occurring right now.
The estimated payload currently does not include the size of the
source-package metadata (technically, the manifest entry in its
archive payload) or the size of any widget metadata associated with
the package's install. In practice this means the preflighted size
underestimates by 3 to 5 KB. In addition, the preflight API currently
cannot distinguish between payload sizes larger than 2 gigabytes;
any payload estimate larger than that is passed as Integer.MAX_VALUE
to the checkFullBackupSize() query.

Recents backup helper
Handles backup/restore of recent tasks for the system. Currently the
thumbnails are not saved.
At restore time the historical task records are placed in a designated
separate location rather than directly in the live bookkeeping; this
avoids ID duplication issues and makes it easier to deal with lazy
adoption of the historical task state as apps are installed on the
device post-restore.
