As long the filter doesn't look into the nsvc/bvc structs
there is no need to use the type.
Further it allows to use the same code for NS1 and NS2.

In case the port isn't known at the time osmo_sockaddr_str_from_str2()
parse only the ip and don't touch the port.
This is the case when a user has different vty commands for ip and port.

The function is checking for IP version matching between local and
remote addresses even if only one is needed based on flags. For example,
if user only desired to bind, the remote address should not be
used nor checked.

On IPv6 sockets, getsockname() and inet_ntop() would act upon a
structure struct sockaddr_in.
First getsockname() would succeed but truncate the address, and later on
inet_ntop would read out of the scope of the structure.

sctp_bindx() fails if passed both "0.0.0.0" and "::", only "::" must
be passed instead, which covers both.
As a result, it is fine in this case and makes sense having only IPv6
formatted IPs in the local side (which actually also includes all IPv4
ones in th system) and IPv4-only addresses on the remote side.

According to 3GPP TS 44.005, section 4.2.2 "Priority":
a) on DCCH, a SAPI=0 frame always has higher priority than SAPI=3;
b) on ACCH, the priority arrangement is more complex:
b1) if a SAPI = 3 frame is awaiting transmission, two SAPI=0
frames shall not be sent in consecutive SACCH frames;
b2) on the network side (LAPDM_MODE_BTS), it must also be ensured
that any SAPI=3 frame is followed by at least one SAPI=0 frame;
b3) a SAPI = 0 frame may be repeated in the next SACCH period
if the Repeated SACCH is supported (see 3GPP TS 44.006, section 11).
We definitely need to extend our testing coverage to ensure that
we implement b) correctly, but for now let's focus on DCCH:
a) for DCCH, ensure that SAPI=0 frames preceed SAPI=3 ones;
b) for ACCH, re-use the existing round-robin implementation.

Recently we've encountered a situation where during MT SMS delivery,
the func=SABM for SAPI=3 was sent on Downlink *before* the BTS
replied with the func=UA for SAPI=0 (contetion resolution procedure,
where we echo the (RR) Paging Response back to the MS).
This change adds a unit test reprodicing the problem.

We intentionally do not match stderr output because it contains
non-deterministic messages (e.g. pointer addresses), so let's
make sure that all test specific messages go to stdout.

This is basically an ACKnowledgement for (RR) CM Service Request,
thus it contains a copy of the original Uplink message (cm).
Let's rename it to reflect this explicitly.

This is basically a successor of gsm0808_create_sapi_reject(), but
instead of hard-coding GSM0808_CAUSE_BSS_NOT_EQUIPPED, it allows
the caller to specify a cause value to be used. The old function
is now deprecated and should not be used.

Some systmes (like the ones available in OBS) don't support creating
SCTP sockets, so we need to skip those tests there.

Under some specific cases, res_loc could be leaked. Under some others,
res_loc and res_rem were freed without being initialized previously.

Drop one of the two log lines since it would be a duplicated and anyway

The function is improved to support AF_INET:v4->v4, AF_INET6:v6->v6 and
AF_UNSPEC:v4+v6->v4+v6.
Unit tests for the function are added to make sure function behaves
correctly in several scenarios.

Address resolution is done first and once we have the information, it
proceeds to create the socket. This separation in steps will help when
adding support for IPv6+IPv4 sets, where AF_UNSPEC is passed and created
socket needs to be AF_INET6 in order to handle addr of both versions.

It's more convenient to use i in the outer loop, and j, k, etc.
in the inner loops. Otherwise it looks a bit confusing.

Shared code might be used by applications that have no vty, so sched
can't be initialized, do not assert and break everything in this case, a
warning should suffice.

When dealing with IPv4 and IPv6 address, the struct sockaddr
allows to hold IPv4 and IPv6.
However even when struct sockaddr is being used, a cast to the
IPv4 or IPv6 family must happen. To work around this additional code,
use a union for the most common types.
