BSC NAT/MUX

=== Introduction ===
The OpenBSC NAT is masquerading multiple BSCs behind one. It listens for incoming BSCs on
port 5000 and connects to a specified MSC. It will forward Paging Requests and MGCP messgaes
to the right BSC (if it is connected). Each incoming SCCP connection gets patched with a different
Source Reference to avoid any collision between the different BSCs.

To the network the NAT looks like a real BSC, to the BSC the NAT looks like almost a real MSC. One
difference is that MGCP messages are not send via UDP but inside the IPA protocol to avoid
any issues with firewalls and such.
