Any package can now participate in backup/restore, without requiring any
manifest-declared permission. *Control* of the backup manager is still
guarded by the BACKUP permission, which is signatureOrSystem.

Applications can now specify two more aspects of the restore process: whether
they need to run with their own custom Application subclass rather than being
launched in the usual restricted mode during restore, and whether it's okay for
the backup manager to kill the app process once restore has completed. The new
manifest attributes for these are, respectively, android:restoreNeedsApplication
and android:killAfterRestore.
If unspecified in the manifest, restoreNeedsApplication is false, and
killAfterRestore is true.
In order to support kill-after-restore cleanly, this change also adds a new
system-process-only interface to the Activity Manager, which will schedule a
"commit suicide" event on the target app's main thread looper.
The framework backup agents have been given the appropriate new backup
attributes as well.
Packages that do not use android.permission.BACKUP_DATA will neither be backed
up nor restored. That permission is currently signature-only. In the future if
access to the backup/restore infrastructure is made available to arbitrary 3rd
party applications, the permission checks (and indeed, the permission itself)
can simply be removed.
This backs up the basic system and secure settings. THe restoration doesn't
take effect immediately. You many need to restart the runtime to see all
restored values take effect.
made public, and wouldn't be used by any third party applications,
and no longer does anything regardless).
Also remove the WRITE_GSERVICES permission from the SettingsProvider
package's manifest (the declaration there was redundant with the one
in the core manifest, where all the other settings-related permissions
live -- no other core package includes its own permission definitions).
