lib/mgcp: Add new port with support to handle multiple MGCP sockets
* Some scenarios like MGW BSC-attached in SCCPlite require handling of
2 MGCP-over-UDP sockets in MGCP Emulation: 1 for regular
libosmomgcp-client from osmo-bsc and another one from the forward socket
from osmo-bsc (of MGCP-over-IPA messages communicated with MSC).
* Old port is kept for backward compatibility with other tests and
enabled by default. It's also interesting to keep it because it makes
tests without special needs (2 sockets) to use the old port/API which
produces simpler code to read and mantain.
* Users of the new port have to enable multi_conn_mode parameter and
expect to interact with port MGCP_CLIENT_MULTI instead of MGCP_CLIENT,
which will offer messages containing information about the UDP
connection being used by that message.
