Service for OEM lock management.
The new service separates OEM lock management from the implementation.
Currently, a user restriction (DISALLOW_OEM_UNLOCK) and the persistent
data block have been used to implement OEM lock management. In future,
other implemention will be used e.g. a secure element.
The new API also allows for a signature to be passed when changing
whether the device is allowed to be OEM unlocked by the carrier which
can be used for cryptographic protection of the flag.
