Now that we have LocalCallingIdentity, we can start caching it in
very narrow cases. We must be careful to not cache too long, since
any changes to granted permissions for the UID mean we need to
re-evaluate any cached answers.
The best middle-ground for this in the Q release is to use an active
camera session as a proxy for when we should create a cache object
and then later invalidate it. (It's very unlikely that a user
changes permissions while actively using the camera, and this is
a strong signal that the caller is sensitive to performance.)
Many other sprinkled optimizations to avoid extra binder calls into
the OS, such as aggressively caching VolumeInfo related details.
Track IDs that are owned by each LocalCallingIdentity, to speed up
all future security checks.
Dispatch all change notifications asynchronously, and delay them by
several seconds while the camera is being actively used, to give
more important foreground work a fighting chance. Invalidate
thumbnails asynchronously.
Optimizations to ModernMediaScanner where it's safe to skip the
"reconcile" and "clean" steps when we're focused on a single file
that we successfully scanned.
Local tests show this CL improves performance of a test app that
takes 100 rapid shots by 45%. (All the collective optimizations
done so far this week add up to a 70% improvement.)

This change adds a mechanism for restricting permissions (only runtime
for now), so that an app cannot hold the permission if it is not white
listed. The whitelisting can happen at install or at any later point.
There are three whitelists: system: OS managed with default grants
and role holders being on it; upgrade: only OS puts on this list
apps when upgrading from a pre to post restriction permission database
version and OS and installer on record can remove; installer: only
the installer on record can add and remove (and the system of course).
Added a permission policy service that sits on top of permissions
and app ops and is responsible to sync between permissions and app
ops when there is an interdependecy in any direction.
Added versioning to the runtime permissions database to allow operations
that need to be done once on upgrade such as adding all permissions held
by apps pre upgrade to the upgrade whitelist if the new permisison version
inctroduces a new restricted permission. The upgrade logic is in the
permission controller and we will eventually put the default grants there.
NOTE: This change is reacting to a VP feedback for how we would handle
SMS/CallLog restriction as we pivoted from role based approach to roles
for things the user would understand plus whitelist for everything else.
This would also help us roll out softly the storage permisison as there
is too much churm coming from developer feedback.

Fix runtime error that was being thrown as Looper.prepare() was not called
in the async function doInBackground.

Test: Was not able to reproduce the bug (that is make code execution flow

* Reproduced by throwing IOException in the try block so that code flows
to the catch block.
* Build and flash.
* Take interactive bugreport and change title and name of the bugreport from
the progress bar.

Only allow rollback to be enabled on the modules included in a mainline
update. We don't want to support rollbacks for all apks in general yet.
Enforce that only installers granted the MANAGE_ROLLBACKS permission can
enable rollback for a package.
Introduce a new TEST_MANAGE_ROLLBACKS permission that can be used to
enable rollback on packages that are not modules. This allows us to
continue testing rollbacks, given we can't do a mainline update as part
of the rollback tests.
Test: atest RollbackTest, with new tests for permissions added.
