function 'UNLOCK'
[Synopsis] Unlocks a named mutex. [Description] Unlocks a previously locked mutex. Returns '1' if the channel had a lock or '0' otherwise. NOTE: It is generally unnecessary to unlock in a hangup routine, as any locks held are automatically freed when the channel is destroyed. NOTE: If 'live_dangerously' in 'asterisk.conf' is set to 'no', this function can only be executed from the dialplan, and not directly from external protocols.
