Implement IuCS (large refactoring and addition)
osmo-nitb becomes osmo-msc add DIUCS debug log constant add iucs.[hc] 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.
