Add implementation of the Telephony and Media Audio Service, as well as
two sample applications.
tmap_central reflects a smartphone implementing the Unicast Media Sender
and Call Gateway TMAP roles.
tmap_peripheral reflects an earbud implementing the Unicast Media
Receiver and Call Terminal TMAP roles.
Upon connection, tmap_central starts an audio stream using CAP Initiator
APIs.
CCP, MCP and VCP are discovered and used to send example commands.
Future improvements: 2-earbud support, add TMAP Broadcast roles,
update with new CAP Acceptor/Commander APIs as they become available
