If we request backup in several chunks, packages like 'pm@' or 'android' get backed up for each chunk, so due to incremental backups, we need to keep old data when comparing.
and cancel observer notification when backup is finished. This is because when the success channel is disabled by the user, the observer notification could stick around and would never get removed.
* Bump version
* 33030020 -> 13-3.2
* 33030021 -> This, d2d test #478
* 33030022 -> Next, to go back to normal build after testing #489
* Set the testing property to true so that the system

14597: Optionally have System-scheduled backups act as migrations | https://review.calyxos.org/c/CalyxOS/platform_frameworks_base/+/14597
Change-Id: I278091b6659db095716e01b6c3894ce345219283
Allow backup of apps that would otherwise only support device-to-device
migration. This is an initial-support patch to help determine the
viability of this approach.
Known issues / TODO:
* System-scheduled backups will not handle D2D-only apps, unless
accompanied by a framework change forcing OperationType.MIGRATION.
Backups triggered by the connection of a USB device or by Seedvault's
StorageBackupService (files) scheduling are not affected, so they
*will* back up D2D-only apps as expected; otherwise, the user may
need to perform a backup manually via Backup Now.
* Apps with `allowBackup="false"` will appear in Backup Status under
"Installed Apps" rather than "Apps that do not allow data backup",
and their status will always be blank until they have been backed
up. If they are not eligible for migration, it will never change.
Other notes:
* The unit test for excluding the Storage Plugin provider from backups
was discussed, deemed unnecessary, and removed.

We emit the install result of APKs at least two times. When there is no APKs to install, because APK backup was disabled, we would start the restore of app data two times.
This fix waits until the emitted install result is considered finished, so we only start data restore once.
If an app being restored was originally installed with F-Droid Basic,
try to install it using F-Droid Basic again.

Restore app data in smaller batches when performing a full restoration
from a backup set, to prevent a Binder exception that causes the
process to fail entirely.
Android may encounter this exception when trying to call the
transport.startRestore() method if too many packages are involved; in
testing, 300 is an example of too many. Instead of using
IRestoreSession.restoreAll(), use restorePackages() and provide the
package names in batches of 100.
This issue reveals itself when using SeedVault with the D2D patch and
with an OS, such as stock Pixel OS, that includes an abundance of
packages. (Prior to this patch, the call to restoreAll() meant that the
framework would request data restoration for all packages installed,
even if they were not in the metadata.)
In logs, this issue appears as follows:
```
I BackupManagerService: Full restore; asking about 300 apps
W BpBinder: Large outgoing transaction of 528540 bytes, interface descriptor <uncached descriptor>, code 14
E JavaBinder: !!! FAILED BINDER TRANSACTION !!! (parcel size = 528540)
E BackupManagerService: Unable to contact transport for restore: data parcel size 528540 bytes
```
