nitb/ctrl: Implement creating and deleting subscribers

Sadly there is no proper foreign key relationship on the tables
that related to the Subscriber. This means we can't use a DELETE
with Cascade and need to delete everything by hand. To make things
worse maybe the SMS/Paging code is still using the subscriber
making the operation more dangerous. I had added NULL checks for
sender_id/receiver_id at 30C3 so we should not crash in this
situation.
