When no remaining signalling NSVCs are available the SNS must be
restarted (BSS) or go into unconfigured state (SGSN).

The problem are recursive execution because a free generates an event which could
allow the use to free a nsvcs while the llist_for_each() is still running

Otherwise there could be recursive loop when free'ing NSVCs which
in the end create an event which the SNS want to free the NSVCs a
second time

When free'ing a NSE/NSVC/BIND ensure there can't be a double

The SGSN fsm should be freed when becoming invalid instead of going
into the unconfigured state. The unconfigured states should be only used
when creating the NSE (on the SGSN side).

The SNS fsm is similar for BSS and SGSN.
Terminate the SGSN failures by freeing the NSE.

The SNS code will always create NSVC on it's own. The only case
when the SNS dialect allows dynamic NSE/NSVC is on the SGSN side when accepting
dynamic NSE and receiving the first SNS SIZE. In this case the NSVC FSM must not be started yet.

Kill programs with SIGTERM with the new vty command, as it would happen
with "systemctl stop".
I've considered running the select shutdown logic too in order to ensure
that pending OSMO_FD_WRITE requests are serviced. But as noted in
review, it's better to ensure that the regular SIGTERM code path works
as expected and call that instead of introducing an alternative code
path.

The FR code is using force unconfigured to change the state of the NSVC
when the FR link goes down. The force unconfigured state didn't
notified the NSE when changing into this state.

The implementation cleary replaces sep_chars instead of keeping them.
Adjust the doc to clarify that.
It seems to me that the intention was to *allow* sep_chars instead of
replacing them, especially when looking at sep_chars of
osmo_separated_identifiers_valid(). But we're stuck with that now.

If the NSVCI is valid, there is no signalling or data weight defined (internally this is 1).
For NSVC with NSVCI don't print the signalling or data weight.
For NSVC without NSVCI, don't print NSVCI at all.

gprs_ns2_free_bind() takes care of all required steps to clean up a bind.
The driver->free_bind() operation only cleans up the driver internal state
but not NSVCs and other generic things.
Fixes a crash when free'ing a bind from the vty which has active NSVCs.

This feature signals support to configure Osmocom Dynamic Timeslot type
as SDCCH8, on top of historically supported TCH/H and TCH/F.
The idea is that when unneeded, the TS is configured as PDCH, and as
soon as there's need for an SDCCH and there's none available, the TS is
dynamically reconfigured to SDCCH8. Once all logical channels in the
dynamic TS are released and hence becomes free, the BSC will reconfigure
it to PDCH.

Prepare for A5/4 support in osmo-msc.
Add new function gsm0808_create_cipher2() which takes a struct as
argument instead of individual fields. This is akin to e.g.
gsm0808_create_handover_request() below in the file, and allows
backwards compatibly extending the argument list without needing a new
function signature every time.
Add struct gsm0808_cipher_mode_command, as argument list for
gsm0808_create_cipher2(), with kc128 included.
Encode the Kc128 IE in gsm0808_create_cipher2().
Implement gsm0808_create_cipher() by calling gsm0808_create_cipher2().

and the range can be specified as string, the same way as we would
specify it in the VTY.

Allow telling osmo_select_main* to only service pending writes (shutdown
mode). Introduce API fuctions to indicate a shutdown request, and find
out whether shutdown is complete.
Some osmo programs have a curious sleep of few seconds upon receiving
SIGTERM. The idea presumably was to finish off pending writes before
halting the program. But a sleep() on program exit is annoying,
especially when there usually are no pending writes, and when osmo-bsc
is launched numerous times for tests.

Use section for all counter headings, the idea is that the generated doc
is included below a chapter describing the implemented counters which
can optionally describe individual items.
If not osmo_counters are present simply omit the whole section to tidy
up the manual. Those are deprecated anyway and not used in the osmo-*
projects that I checked.

This commit fixes crash when response is more than ~4096 chars.
Furthermore, we now allocate only the required memory, not 4096 for all
messages, which usually don't require it.
Test needs to be adapted since it assumed there was more available space
at the end of the msgb.
