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.

This bug showed up when running the whole TTCN3 hnodeb-test testsuite.
llsk_audio_sapi_version_confirmed() was setting the expected struct size
fo the version previously set.

This commit introduces support for the new llsk_audio SAPI v1.
This new version is almost the same as v0, with the exception that
primitive <REQUEST,HNB_AUDIO_PRIM_CONN_ESTABLISH> wins an extra field
appended at the end:
"""
uint8_t rfci[HNB_MAX_RFCIS]; /* values range 6 bits */
"""
This allows lowerlayers to provide an unordered array of RFCIs, which
was seen may happen under some conditions. For instance:
"""
rfci[HNB_MAX_RFCIS] = { 2, 3, 1};
[0] RFCI 2
[1] RFCI 3
[2] RFCI 1
"""
OsmoHNodeB still supports v0 if the lowerlayer asks for it, and will
continue having the exact behavior as before in this case (using
position in the array as RFCI). Hence, no compatibility breakage occurs
in this patch. New clients, on the other hand, can provide the extra
information by announcing V1 support during version negotiation at
startup.

NOTICE: This commit implies an API change when using libosmogsm.
However, the previous API was never available in any libosmogsm release,
and only available in both libosmogsm and osmo-hnodeb master, so we are
only breaking compatibility between different master versions, which is
acceptable.

We build with --enable-werror during development and in CI. If the code
is built with a different compiler that throws additional warnings, it
should not stop the build.
This patch also effectively removes dependency on autoconf-archive.

It doesn't make much sense to pull whole libgtp to implement only the
user plan side of GTP. Let's drop it and add a minimal GTP-U
implementation here.

Use the recently introduced IuUP support in libosmocore to send and receive
proper IuUP over RTP instead of regular RTP.
The LLSK AUDIO primitives are updated to provide required information
back and forth.

This config file is also installed and used by the systemd service by
default. Local ip address of 127.0.0.3 is used by default to avoid
collisions with default configs of osmo-sgsn and osmo-ggsn.

This is needed for instance:
* AUDIO: video calls
* GTP: secondary pdp contexts
For better abstraction, now both AUDIO and GTP conns use unique ID
namespaces, and one ID is used to identify each one. Each conn relate in
turn to a UE since a context_id is passed during connection
establishment.

This first implementation uses libgtp to manage the GTPv1-U socket and
pdp contexts, as a proof of concept to have something working for now.
At a later step, it is expected to drop libgtp and use some adhoc code
to handle GTP-U.

This first version can send and receive regular RTP, but does not talk IuUP.
Support for IuUP will be added in a future patch. This way we can
already test the whole LLSK<->RTP path.

The LLSK socket is an interface allowing thid-parties to implement and
hook their RLC/MAC/RRC stack to osmo-hnodbe, which takes care of
interconnection with the rest of the RAN and core network (Iuh, RTP,
GTP-U, etc.).

The higher level bits were used in originally imported hnb-test code in
order to control interaction with the HNBGW over the VTY. This is no
longer needed in osmo-hnodeb, as NAS is in layers above the ones being
handled by an hNodeB.
Regarding RANAP, most of it is going to be handled by the LowerLayer UD
socket peer to be introduced in the future, so we can drop most of it,
as in osmo-hnodeb we'll basically be speaking RUA to the HNBGW and
passing RANAP buffers transparently.
We keep the .c/.h files since some small helpers functions will be
ntroduced later on when adding support for the mentioned LL socket.

The shutdown_fsm doesn't do much right now, but it's included there in
order to allow easy clean up of resources upon Iuh reconnect in the
future, as well as reset the lower layers.

The Iuh code will be further extended next to properly support
reconnect, and hnb will also gain proper shutdown support soon.

autoconf-archive is apparently needed to build the package. We have it
in few other Osmocom projects as build dependency too, others seem to
ship related m4 macros directly in a m4 dir.
