This option should be used for any executables which are used only
for testing, or for generating other files and are consequently never
installed. By specifying this option, we are telling Libtool that
the executable it links will only ever be executed from where it is
built in the build tree. Libtool is usually able to considerably
speed up the link process for such executables.

The field already exists in the struct, but it's not really used
anywhere internally yet (and was not available externally).
Let's make it available to users of the API, similar to osmo_sccp_user_{get,set}_priv().
This way apps can easily store per-sccp-instance state.

As a result we move from:
INSERT=O(1) SEARCH=O(n) REMOVE=O(1)
to:
INSERT=O(log(N)) SEARCH=O(log(N)) REMOVE=O(log(N))
So we get rid of O(n) complexity every time we need to find a conn
object based on conn_id. When a big number of SCCP conns is handled,
this saves a lot of CPU time every time a conn needs to be looked up,
for instance each time a message is received.
For instance, given 1500 SCCP conns, searching is ~10 steps while it
took 1500 steps beforehand.
Morever, since when creating a new conn_id the code looks if it exists
prior to it, that means in practice inserting used to took O(n), while
now it takes O(log(N)).

The 0x00FFFFFF source local reference is reserved in M3UA/SCCP, hence
avoid allocating a conn_id with that value since later on when reused as
a source local reference it would fail to be encoded.

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.

Silence the error log for PCSTATE.indication prims.
When running the HNBGW_Tests.ttcn suite, the osmo-hnbgw LOGL_ERROR is

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

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.
