This commits adds a generic mechanism for applications to validate
support for SAPs and specific versions of them.
A new special SAPI is introduced to manage inbound control messages for
the protocol.
In that SAPI a new primitive HELLO.req/.cnf is added to negotiate
support for versions of any given SAP.
The idea is that the client upon connecting submits a HELLO.req(SAP,
VER) for each SAP it plans to use, including the version of the special
CTL SAPI itself (preferrably to be checked first).
Upon receiving such a message, osmo_prim_srv handles it using a special
path, which ends up calling the user provided rx_sapi_version_cb(SAP,
VER). In there, the user can either:
* Accept the version (return same VER value)
* Reject the requested version but propose another candidate version
(return some positive VER value other than received VER). In this
case, the client can decide whether to request another VER or close the
connection.
* Reject the proposed version and close the connection.

This new module allows easy exchange of osmo_prim based data types over
IPC communication (UD socket supported only so far), by replacing the
osmo_prim_hdr struct with a serialized header when submitting/receiving
it from the IPC socket.
This patch introduces the server side of the UD socket, but the client
side can easily be introduced in the same file whenever needed.

This makes it easier to follow the general path selection based on
protocol type. It will also make it easier when we add new paths based
on socket domain.

These value_strings are taken from existing private ones in
libosmo-sccp.git osmo_ss7.c, and are moved here in order to be
reused by other projects, such as osmo-hnodeb.

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.

The only reason we have a libosmo-netif -> libosmo-abis
dependency is the lapd examples whihc are built but not even installed.
Let's build those only if --enable-lapd-examples is specified at the
command line, and remove the dependency to libosmo-abis in all other
cases.

The for loop in osmo_amr_bwe_to_oa, that converts the body part of the
AMR payload runs one byte too far. This may cause that some of the
padding bits in the end are not set to zero. The loop is designed to
convert n-1 bytes and the nth byte is done separately at the end.

Size of a single AMR frame doesn't always shrink by a byte when
converted from octet-aligned to bandwidth-efficient mode. It does
shrink for AMR modes 2, 3, 4, 6, and 7 but doesn't shrink for
AMR modes 0, 1, 5, and SID frames because we only remove 6 bits.
So old code generated truncated AMR packets for those AMR modes.
This patch fixes the length calculation by properly counting bits.
Proper bit counting is also bringing us one small step closer to
properly handlig multi-frame AMR packets.

As pointed out at https://github.com/libexpat/libexpat/issues/312
libtool does not play nice with clang sanitizer builds at all.
For those builds LD shoud be set to clang too (and LDFLAGS needs the
sanitizer flags as well), because the clang compiler driver knows how
linking to the sanitizer libs works, but then at a later stage libtool
fails to actually produce the shared libraries and the build fails. This
is fixed by this patch.
Addtionally LD_LIBRARY_PATH has no effect on conftest runs during
configure time, so the rpath needs to be set to the asan library path to
ensure the configure run does not fail due to a missing asan library,
i.e.:
SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan'
export CC=clang-10
ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`)
export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS"

It makes a lot more sense calling it this way since it matches the state
of the stream at that point.

It's not really needed right now from logic point of view, since we
reused NONE for that. But it makes logging and logic clearer, and will
make it easier if we decide to move it to FSMs at a later point in time.
Other state value_string names are also modified with its whitespace
removed since anyway we'd need to change them to match WAIT_RECONNECT
length. Let's drop the space because imho it's not that useful and
anyway if we move to FSMs at some point then we won't have them anyway.

With previous state, osmo_stream_cli_close() could be called from
osmo_stream_cli_open()(), and in that case state was kept as NONE while
ending up with an associated fd being registered in the select loop.
As a result, osmo_stream_cli_fd_cb() could be called while in state
NONE, which was not expected and would simply return without modifying
fd state flags, causing it to be called again and again.

It should not happen anyway because no fd should be active if state is
NONE, but still it's an extra check.

This check was added during libosmo-netif's initial commit, and there's
nothing requiring DAHDI in here. It's most possible a copy-paste
artifact when creating configure.ac.

Similar to what we do in libosmocore already, we want to
deterministically enable or disable support for the feature without
having into account if the system has a libsctp. If libsctp is missing
and support is enabled, then fail.
Extra checks are also added:
* Check netinet/sctp.h header
* Check libosmocore was built with libsctp support (API
osmo_sock_init2_multiaddr() we require).
* In stream.c make sure it can be built without HAVE_LIBSCTP, and that
set_addrs() fails for more than 1 address (since that feature is only
supported through osmo_sock_init2_multiaddrs()).
