Rather than deleting the NSE from memory, we simply mark it as non-persistent.
This makes sure that there are no invalid references (e.g. from gbprox_peer)
to the gprs_nsvc structure, but at the same time ensures it will no longer
be stored as part of writing the config file.
So far, we only started the ALIVE procedure on RESET-ACK if the
remote end was the SGSN. This resulted in the BSS->Proxy connections
only being tested for alive-status from the BSS side, but not from
our side.
Also: export nsvc_by_nsvci() function as a public API function.
This is a generic MI extraction for the MI if it is followed
after a classmark. For the Phase1 Phones the classmark2 is not
four bytes but it might be different. This code can be used
by the CM Service Request handling as well.
We go from no size checks to some content checking. We should
refactor the whole classmark2 + mi parsing that is used throughout
the code into one place with proper size checking. This is the
start and requires a new libosmocore as well.
Using "end" you can always return to the "enable" level, and from
there the "show" commands are available. So no more need for
exit/exit/exit/exit/disable.
Some BSS that connect to the proxy do not continue to perform the
RESET procedure after a timeout. In order to resurrect them, we
simply start a RESET procedure.
We now actually are much more in line with what the specification
says. We track the blocked/unblocked state, we don't accept
signalling messages on PTP functional entities (and vice versa),
and we don't simply create a BVC context with messages other than
BVC-RESET.
Don't allocate a LLC Entity just because BSSGP passes any random
SAPI/TLLI up to us. We can only do this for XID and UI frames
of the GMM SAPI.
Furthermore, add more comments and debug messages.
I want to have a shorter lchan summary but with the same
config parameters. Change the current code to be a method
that takes a dump routine as parameter.
Add the rach emergency call allowed (0|1) setting and implement
it by directly manipulating the t2 value. It is the third bit which
is set to 0 when emergency calls are enabled and to one if it is
only enabled for access classes 11 to 15.

In the previous code we used a static fake_nsvc structure in
case we needed to send a message to an unknown NSVC for which
we don't have a real 'struct nsvc'. However, since we now have
a rate_ctr_group hanging off the nsvc, the fake structure didn't
have that.
So now we keep a nsi->unknown_nsvc around to be used whenever
we need a nsvc but don't have a real one. The gprs_ns_vty.c
code explicitly does not list that NSVC in 'show ns'
