Neels Hofmeyr b271e46049 move libiu to osmo-iuh/libosmo-ranap
Remove libiu here, use the functions from libosmo-ranap instead, by applying
the ranap_ / RANAP_ prefix.

Corresponding change-id in osmo-iuh.git is I6a3f7ad15be03fb94689b4af6ccfa828c25f45c0

Harald Welte a929299cc4 WIP: Port to new libosmo-sigtran API (with proper M3UA for Iuh)
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.

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.
