This changes over to the new libosmo-sigtran API with support for
proper SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for
the IuCS and IuPS interfaces.
Only the ASP (client) is used, assuming that both the HNB-GWs and RNCs
as well as the MSCs and SGSNs are all connecting as ASP to some STP/SGW
which offers M3UA server functionality as well as point-code and/or
global title based routing.

add msc vty, remove nitb vty
add libiudummy, to avoid linking Iu deps in tests
Use new msc_tx_dtap() instead of gsm0808_submit_dtap()
libmgcp: add mgcpgw client API
bridge calls via mgcpgw
mgcp: hack RAB success from nano3G: patch first RTP payload
The ip.access nano3G needs the first RTP payload's first two bytes to read hex
'e400', or it will reject the RAB assignment. Add flag
patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on
a stream, and overwrite its first bytes with e400. This should probably be
configurable, but seems to not harm other femto cells (as long as we patch only
the first RTP payload in each stream). Only do this when sending to the BTS
side.
