Let's disable category here since we don't care about its formatting here.
In any case, every test relying on logging output validation should
always explicitly state the config to avoid issues in the future if
default values change.

A DUPU message in SUA and M3UA indicates the unavailability of
a (MTP-level) user, i.e. the entire SCCP, ISUP, ... is not available.
If we receive a DUPU (destination user part unavailable) message in ASP
role, then we must
* distribute it to any other ASPs for which we operate in SG mode
* pass it as MTP-STATUS.ind to SCCP, which can then generates
N-PCSTATE.ind to the SCCP User

When a SSP (Subsystem Prohibited) or SSA (Subsystem Available) SCMG
message is received, we must generate the respective primitives towards
the SCCP user.

Unlike M3UA, in SUA a DUNA/DAVA message can contain not just the point
code that became available / unavailable, but it can also include a SSN.
In that case, it is just the SSN that became available/unavailable, and
not the entire point code. Hence, a N-STATE.ind and not a N-PCSTATE.ind
must be delivered to the SCCP user.

SCMG (SCCP Management) is a special sub-system that normally resides
at SSN=1. In Osmocom we so far ignored its existence. However,
in terms of interop with other implementation, we should implement
at least some basic features.
The only procedure implemented in this initial commit is the response
to an incoming SST (Subsystem Test) message. If we don't respond to
this message, a remote SCCP entity could assume the SSN is dead on
our side, rendering communication impossible.

M3UA and SUA have one sub-protocol called [S]SNM, through which the
SG informs the ASP about certain destinations (point codes) becoming
available (DAVA) or unavailable (DUNA) in the SS7 network.
This patch adds support for
* generating DAVA/DUAN on a SGP when the AS FSM changes to/from AS-ACTIVE
* receiving DAVA/DUNA on an ASP and informing other "SG role" AS/ASP
* processing DAUD from ASP received by SG, generating relate DAVA/DUNA
responses

When receiving user-data (connectionless / connection-oriented),
we must make sure that there either
a) no routing context IE in the message, and only one AS within the ASP, or
b) a valid routing context IE for an AS within the ASP
This important input validation has been done in M3UA for a long time,
but somehow never been implemented on the SUA side so far.

Fix 'error: initializer element is not constant' with debian 8's gcc
4.9.2, triggered by XUA_HDR. Create a new _XUA_HDR without the type cast,
and use it inside of const struct definitions in xua_test.c. The new
macro is needed, because removing the type cast from the original
XUA_HDR would break other uses.

The ipv4 addr in addr->ip.v4 is already in network byte order, as it's
usual in struct in_addr (see sua_addr_parse_part()).
So the code in there was simply calling ntohl() because
msgb_t16l16vp_put_u32() is calling htonl() on the given parameter before
storing it. Let's simply use msgb_t16l16vp_put() directly and avoid a
double byte swap which only adds confusion.

Otherwise it would end up attempting to connect "::" -> "1.2.3.4" which
would fail during osmo_sock_init2_multiaddr(). If local address is unset
(default), but only IPv4 addresses are set on the remote, then one must
use "0.0.0.0" instead.

Quoting 3GPP TS 23.003 8.2:
1111 1010 BSC (BSSAP-LE);
1111 1011 MSC (BSSAP-LE);
1111 1100 SMLC (BSSAP-LE);
Hence the SMLC one should also be named *_BSSAP_LE.
I'm certain no other osmocom code is using this SSN yet, but anyway keep a
backwards compat shim #define.

This patch is a fixup or extension of commit
96d348efbf, which only fixed the default
values for "asp" VTY node, but not for the xua server's "listen" node.
As a result, without this patch, by default the SCTP server socket will
only listen on IPv4's "0.0.0.0", since NULL is resolved by getaddrinfo
to it instead of "::" as first candidate.

Until now, host list validation was only taking into account a set of
ipv4-only addresses. As a set can contain now IPv4 and Ipv6 addresses at
the same time, we need to do ANYADDAR validation against addresses of
that specific version inside the set.

Previous commit changed the default bind/listen address of the server
from NULL (0.0.0.0) to 127.0.0.1, hence breaking some setups where no
"local-ip" was defined and hence from then on were only listening on
localhost by default.
Let's instead bind to "::" if IPv6 is available, which covers any IPv6
and/or IPv4 address. If not available, keep binding to 0.0.0.0.
Similarly, if IPv6 is available set default remote to both ::1 and
127.0.0.1 to allow it working against processes listening on IPv4 or
IPv6 addresses.

This reverts commit 0b39f2cf7b.
Reason for revert:
Breaks ttcn test suites (at least for osmo-bsc) with osmo-stp error log:
"MTP-TRANSFER.req for DPC 187: no route!"
The breakage is fixed by only reverting the NULL -> "localhost" change
back to NULL. But the commit log indicated a reason for this, so rather
reverting the entire commit for now.

In osmo_ss7_vty_go_parent, "127.0.0.1" is changed to "localhost" to let
local NSS decide whether to use IPv4 or IPv6. In newish systems, IPv6
::1 will be selected since IPv6 takes precedence over IPv4.
Similarly, the default source addr needs to be changed from NULL to "localhost"
since for some yet unknwon reason, getaddrinfo(AF_UNSPEC, NULL) returns
first IPv4 "0.0.0.0" and later "::", which is inconsistent with
getaddrinfo("localhost") result, resulting in src=IPv4(0.0.0.0) and
dst=IPv6(::1), which is incompatible and will fail.
In any case, this change doesn't affect users of osmo_sccp_simple_client
because the APIs set both src and dst addresses.

A message like

Our manuals explain that the cs7 config automatically adds missing parts.
However, previous code requires an ASP to exactly match the default name that
the autoconfiguration would choose -- that is unintuitive.
If a config included only an ASP, or both AS and ASP but omitting to add the
ASP to the AS, auto configuration would pick it up iff it exactly had the name
the application chose. For osmo-bsc, that was 'asp-clnt-msc-0', if 'msc 0' is
the first MSC in the config file. For osmo-msc, it is 'asp-clnt-OsmoMSC-A' or
'asp-clnt-OsmoMSC-A-Iu' and so forth, so it is not always clear which name the
user should pick to get the ASP used by auto config.
Refactor so that any ASP with a matching protocol that is not associated with
any AS yet is picked up by the auto configuration, i.e. associated with the AS
etc., regardless of the name chosen in the config file.

In I9b3ae6dfcf6efeabb7fb6c33503d1d7924fec2fa we fixed some problems
regarding rapid open/close cycles of inbound M3UA client connections.
Unfortunately the fix now triggered another bug.
xua_srv_conn_closed_cb() is called by libosmo-netif stream code whenever
a connection (socket) is closed. As the stream_server is de-allocated
right after this call-back, the call-back must make sure to remove
any pending references to the stream_server.

This reverts commit ec20a6164b.
Reason for revert: this patch makes specific variants of 'cs7'
config fail. In short, if AS and ASP are configured and connected,
the ASP is never started. See OS#4635 for elaborate details.
