Split permissions inherit state from their parents

The old hack to grant permissions on upgrade was removed. The new code
applies to
- platfrom upgrade
- initial package installation
- package update

Inheriting the grant state is the default behavior for split permissions.
Special cases will be added later.

Also make sure to revoke the permission once the app declares that it is
aware of the permission.
