sms: Add code to migrate the database to the new schema

This is mostly based on Alexander's migration code. The code
adds transaction handling and some sanity checks and cleanups
to the code. We made the decision to fork the sms_from_result
method and freeze it to that version. This way sms_from_result
can move forward without having to deal with legacy.
