Add WIP code for SCCP User Adaptation (SUA) and SCCP User SAP
The idea of this code is to
* provide a SCCP User SAP as boundary between the User of SCCP
or SCCP-like transport like SUA
* implement the minimum subset of SUA to transport RANAP messages
betweene HNB-GW and MSC/SGSN
At this point
* we don't yet implement the proper state machines and timer
* we don't imp[lement the SCCP RESET procedure
* we don't implement AS/ASP management
The code is full of FIXMEs whihc hopefully will get fixed gradually.
After some cleanup + verification, it should move to a library, possibly
either replacing/renaming libomo-sccp, or adding it to libosmo-netif?
