I would like to tweak the names for the recently added functions, so
that they are more clear -- quickly before we release it or anyone uses
these.

The attempt to route message via AS which is down will fail anyway:
let's make it explicit.
Add osmo_ss7_as_down() and use it to check AS state before transferring the message.

Add non-legacy string functions for osmo_scu_prim_name in the form of
_buf() and _c() signatures.
So far there is only osmo_scu_prim_name() using a static buffer.
Implement that using osmo_scu_prim_name_buf().

Silence the error log for PCSTATE.indication prims.
When running the HNBGW_Tests.ttcn suite, the osmo-hnbgw LOGL_ERROR is
spammed with messages like:
DLSCCP ERROR unsupported SCCP user primitive N-PCSTATE.indication (sccp_scmg.c:298)
Add this prim to scmg_prim_cb() to just log on DEBUG that it is ignored.

SUA allows references of 4 bytes, but SCCP/M3UA doesn't.
SUA: RFC3868 sec 3.10.4:
The source reference number is a 4 octet long integer.
This isallocated by the source SUA instance.
M3UA/SCCP: ITU-T Q.713 sec 3.3:
The "source local reference" parameter field is a three-octet field containing a reference number
which is generated and used by the local node to identify the connection section after the connection
section is set up.
The coding "all ones" is reserved for future use.

By default systemd will execute service with root directory
(or home directory for user instance) which might result in
attempts to create files in unexpected place. Let's set it
to 'osmocom' subdir of state directory
(/var/lib for system instance) instead.

The length limit of optional Data parameter is 130 bytes according to ITU-T Rec Q.713 §4.2..§4.5. If we receive CR, CC or
RLSD message with bigger data - cache it if necessary and send via separate DT1 message after connection becomes active.

Previously DT1 message sent via osmo_sccp_tx_data() was silently truncating data if it was over 256 bytes. Let's fail
explicitly and let caller handle this.

This is similarly done for same IE in other functions, so let's do it
here too in order to make coverity happy, and avoid random access ptr
probably ending up in obscure crash.

If we receive any M3UA/SUA SNM SCON mesasages, distribute them
to any other active ASP to make everyone aware of the congestion
situation.
This makes STP_Tests_M3UA.TC_ssnm_distribution_scon pass and hence
should turn the entire osmo-stp test suite "green"

When using 'check_PROGRAMS', autoconf/automake generates smarter

the normal 'make all', but only during 'make check'.

Otherwise when configuring ss7 instances in numerical order in the VTY

As of GCC 11.1.0, it starts printing a warning about uninitialized
variable. It is a false positive since tmode is really only used in the
case where traffic_mode is not zero, in which case tmode is set.
Let's restrict the scope of tmode to fix the issue and also make it
clearer where the variable is used.

Add a new function similar to osmo_sccp_addr_by_name, but search in a
specific ss7 instance's addressbook instead of searching in the global
address book. This is needed for osmo-bsc-nat, which uses two separate
instances at the same time.

run in ASP role. Even then when the user has configured it differently
via VTY. The osmo_sccp_simple_client should respect the VTY

Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

When introducing rate_couters, I forgot to call
rate_ctr_group_free(). I thought free'ing the parent object
via talloc is sufficient, but that obviously misses the point that
rate_counters have an internal linked list from which they must be
unlinked.
