mgcp: use osmo-mgw to switch RTP streams
osmo-bsc currently negotiates the RTP stream directly with the
BTS and reports back the RTP IP/Port on the BTS. This works fine
for a single BTS, but for Handover the port/ip pointing to the
MSC side must not change, so an entity in between the BTSs and
the MSC is required.
Integrate the mgcp-client and use osmo-mgw to switch the RTP
streams.
