Use the VTY to configure the connections between BSC and MSC
on both sides.
We now can add new connections, we also can write the config,
removing existing connections is implemented on the MSC side,
but not yet on the BSC side.

Currently all sccp addresses on the msc (and bsc)
side are hardcoded.
Prepare the msc code to make the associated BSCs
configurble. Make the compiler link libosmo-sccp
properly and start using the sccp addressbook
feature of libosmoc-sccp.

Clearing all endpoints by sending a DLCX on startup has ben found
to be a bit too offensive. It also will not help against
inconsitancies that may occour during runtime (e.g. an overheard
DLCX during regular call teardown).
This reverts commit b669ea94cb78fd9b56ee8dd9392538151349f8ba.

If the MSC is crashing and restarting, it may leave some endpoints
open. The endpoints can not be re-used until they are deleted
(DLCX). This patch sends a DLCX to all possible endpoints (usually
this is in a countable range) in order to clear possible open
endpoints from a previous run

So far CTRL was not used by anyone, and was still disabled from the initial
implementation of the OsmoMSC. Now we need it in osmo-gsm-tester.
Only add the MSC specific CTRL commands, the bsc_base_ctrl_cmds_install() still
needs to be split up.

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 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.
