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-msc is going to use this to route RTP streams (for 3G at first). Change-Id: I6fe365c4c89207f2172943cc456b508a207b1135
