mpmd: Add get_mtu() API and MTU discovery for UDP transports
The mpmd_xport_mgr classes can now return their own MTU. The UDP xport
manager is a special case, it doesn't actually know its MTU, and thus
runs an MTU discovery, using the MPM-ECHO command to discover MTU by
sending variable-size packets as a probing mechanism.
