Re-introduce support for IPA-encapsulated MGCPlaforge/mgcp-ipa
Old osmo-bsc-sccplite already supported this, but in the migration over to libosmo-sigtran and to real 3GPP AoIP, this functionality got lost. We now crate a UDP proxy socket. Any MGCP commands received via IPA from MSC (or rather: bsc_nat) are retransmitted to the MGW via UDP on this socket. Any responses back from the MGW received on the UDP socket are retransmitted back to MSC/bsc_nat as MGCP inside the IPA multiplex. Closes: OS#2536 Change-Id: I38ad8fa645c08900e0e1f1b4b96136bc6d96b3ab
