libmgcp: add mgcpgw client API
Add an API to send MGCP messages to an MGCP GW, from the perspective of
an MSC instructing the GW to setup RTP streams.
Rationale: the mgcp_protocol.h is mostly for the MGCP GW itself, other
implementations forward incoming MGCP messages. So a simpler approach for an
MGCP GW client is useful.
Add general VTY commands that can be used to configure mgcpgw_client.
osmo-cscn is going to use this to route RTP streams (for 3G at first).
