Ensure that existing binds are updated as well.
In some cases the default max length of the osmo_io txqueue could be too
small. Set it to 128 by default and add a VTY option to change it for
an NSI (program-wide).

Allow to restart SNS procedure and initiate a SNS-SIZE procedure with Reset.
SGSN side SNS restart will stop answer on ALIVE and is sending NS STATUS
invalid protocol state.
BSS side SNS restart will send a SNS Size procedure to reset the state.

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.

DSCP is a 6-bit value (0..63) stored in the upper 6 bits of what was
formerly known as TOS bits. We must
* make sure the user can only specify 0..63
* shift the value by two bits when using the IP_TOS socket option
We achieve the latter by using the recently-added osmo_sock_set_dscp()
helper.

In the IP-SNS SGSN role, we need to inform the BSS of our local
IP endpoints. For statically configured NSEs, those are explicitly
stated on a per-NSE level.
For dynamically created IP-SNS NSEs, we are adding a new VTY
command, using which the administrator can configure which binds
should be advertised as IP endpoints to such BSS.

Setting the NSE dialect possibly involves the creating (or destruction)

Introduce a `ip-sns-bind BINDID` vty command within a `nse` vty object.
The ip-sns-bind defines the binds which will be used by the dynamic
configuration with IP-SNS.
This is only the first part which only uses the binds when doing a
new SNS configuration.
The outgoing add procedure will be supported in a later patch
when the SNS fsm supports outgoing procedures.
This is a behaviour change of the API and must be synchronized with
the osmo-pcu. Otherwise SNS won't work with osmo-pcu.
