Many fixes.

This release contains a new system-app-only permission that is sometimes required on Android 10-11: you need to unsystemize the old version and systemize the new version to get this permission.

New permanent change to your system: on Android 12 or higher, global setting uids_allowed_on_restricted_networks will be changed if you do not install this app as system app to grant an equivalent permission to this app.
