mgcp: Merge OpenBSC MGCP code and update the structure to match it
* Upstream has a separation of BTS and NET side for RTP ports and can allocate them dynamically. * Upstream has gained the concept of trunks. We will now have various trunks to connect audio things. * We will now be able to utilize multiple trunks and have the endpoints used properly.
