The logic in MediaProvider is technically correct, but it's sometimes
inefficient in calling into the OS multiple times with the same
questions, such as validating getCallingPackage().
To mitigate this overhead, and start paving the way for more dynamic
delegation of permission checks, collect these details into a
LocalCallingIdentity object. We carefully perform all permissions
checking against this new object, and avoid using any other
thread-local values from ContentProvider or Binder.
Local tests show this CL improves performance of a test app that
takes 100 rapid shots by 37%.
This change is a no-op refactoring.

The code allows to also whitelist only a select set of permissions, but
this is not yet exposed in the API.
Also: Fix up shell commands for restricted permissions

Test: - Enabled app via device admin in secondary profile
-> verified that permissions were whitelisted
- Installed existing and new app using --restrictpermissions and
not
-> verified that permissions were whitelisted or not

Adding a new intent acttion for the permission controller to ask an
app to show its permission usage to help the user understand what
and why is being used. We are adding a permission to protect this
action to prevent apps trampolining into other apps when asked to
show their permission usge.

Make PackageManager send a ACTION_CANCEL_ENABLE_ROLLBACK intent to
RollbackManager. RollbackManager marks the relevant rollback as invalid.
Allow enable rollback to continue as usual, before making the rollback
available, RollbackManager checks whether it's valid. If it's not, the
rollback data is deleted.
Add a test case for expired rollback enabling attempt in RollbackTest.
Test: atest RollbackTest#testEnableRollbackTimeoutFailsRollback
Test: manual -
* Set ENABLE_ROLLBACK_TIMEOUT_MILLIS to 1 ms using DeviceConfig
* Install a mainline module with rollback enabled
* adb shell dumpsys rollback
* observe that no rollback was made available

This change removes the permission granting for non-system dialer and
SMS apps in DefaultPermissionGrantPolicy. Permission granting to
system apps is left unchanged. Package manager is also made to query
role manager for the current default dialer instead of maintaining its
own storage.

To ensure existing installers would work without a change the
default state of installing a package is now that all restricted
permissions are whitelisted. If the installer specifies another
whitelist at install time, it determines the install state. In
addition to this we now enable the restricted permission checks
as a prebuilt installer is no longer required.
