res_telos_1a2: Add support for Telos 1A2 interface module.

Add an Asterisk module to interface with a Telos 1A2 interface
module over a serial connection. This hardware provides line
status information for a 1A2 key system; using this information,
Asterisk can then provide line information and furnish music on
hold to 1A2 systems without any music on hold KTU cards, using
the standard Asterisk music on hold facilities.
