AST-2014-018 - func_db: DB Dialplan function permission escalation via AMI.

The DB dialplan function when executed from an external protocol (for instance
AMI), could result in a privilege escalation.

Asterisk now inhibits the DB function from being executed from an external
interface if the live_dangerously option is set to no.
