The code currently uses an encoded sequence of (hex) 10 20 30 40 50
60 as RAI, for which no bijective mapping to the set of
representations MCC-MNC-LAC-RAC exists.
This patch changes the hard-coded RAI to 11 22 33 40 50 60 which maps
to 112-332-16464-96 (and vice-versa).

The gbproxy looses NSEI changes on BVC_RESET and then tries to send
later messages to the wrong (not longer existing) destination.
This patch fixes this by updating the peer's nsei field on BVC_RESET.

This checks the behavior of the gbproxy when the BSS peer changes the
NSEI and the NSVCI. It also tests BVC_RESET and other UNITDATA
messages after these changes between BSS and SGSN and vice versa (via
the gbproxy).

Currently such messages lead to a creation of a new peer with the
SGSN's NSEI, which results in echoing the message back to the SGSN.
This patch modifies this by sending a STATUS response (invalid BVCI)
instead back to the SGSN.

This adds a test with a UNITDATA SGSN message that is addressed to an
invalid (unknown) BVCI. The test shows, that the message is echoed to
the SGSN.

This adds counters that are incremented when errors are detected.
It also modifies the VTY command 'show gbproxy' so that
'show gbproxy stats' shows the counters.

This adds a simulation of the SGSN side of the Gbproxy. The VC is set
up correctly and several combinations of BSSGP messages are sent.

Currently in most places in gb_proxy.c a reference to a NS-VC object
is used where the peer is meant instead. The patch changes this by
using the NSEI instead in these cases.

This program tests the gbproxy implementation by passing NS messages
to a modified gbproxy that dumps the resulting messages, signals, and
state.
It focusses on testing abnormal situations like port changes.
