Until now, the osmux_out_handle was allocated by the client, and passed
to the API to initialize it. This makes it really hard to improve the
implementation without breaking the ABI.
Let's break the ABI now one last time (hopefully) by allocating the
struct through an API. With only this change, the already built users
(osmo-mgw, openbsc) can still work fine, since there's no change on the
struct osmux_out_handle. However, they will somehow break next time the
struct is changed until they are ported to the same API (easy to do).

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.

Closes: OS#4726
New define is available since libosmocore 1.1.0, and we already require
1.3.0, so no need to update dependenices.
Let's change it to avoid people re-using old BSC_FD_* symbols when
copy-pasting somewhere else.

Add functions to get the description of a server link or client
connection which examine data on corresponding socket.
Those functions use static buffers and intended for single use in
log/printf statements as illustarted by corresponding example changes.

Stream server example had an error which resulted in infinite loop on
client disconnect. Fix this by properly handling client closing
connection to allow it to reconnect multiple times.

Set category filter to make sure internal library logging won't
interfere with example's own logging. It's also nice example
illustrating log_set_category_filter() usage.

In libosmocore Change-ID I1834d90fbcdbfcb05f5b8cfe39bfe9543737ef8f
we have introduced ipa_ccm_id_resp_parse() as a bugfixed replacement
of ipa_ccm_idtag_parse().
The main difference is that the returned "value" parts now have
a correct reported "length", whereas before this commit they all
reported a one-byte too-long "length" for each IE.
Let's use this opportunity to remove the copy+pasted
osmo_ipa_idtag_parse() function from the libosmo-netif codebase.

The "channel" layer on top of IPA client + server was introduced in
2011 but never used in any osmocom program/project so far. Contrary
to the several other IPA multiplex related implementations in libosmo*,
it did not deal properly with segmented IPA messages, i.e. where a
single TCP segment (and hence recv/read call) does not contain a full
IPA message.
So rather than fixing it up and having yet another IPA related API in
our libraries, let's remove it.

In addition to showing basic UDP send/receive example, it helps to test
corner-case when dealing with 0-length UDP packets.

Use the new macros to deal with little/big endian. Im a bit
worried to make this change due the little test coverage in
this module but in case of a typo the elements would not be
defined.

Remove these functions:
- osmux_xfrm_input_get_ccid
- osmux_xfrm_input_register_ccid
The ccid will be managed by the BSC and it will be stored in the
mgcp_endpoint structure.
Also adjust all tests and examples using the API.
You can use these utilities to test osmux:
1) in one console, run ./osmux-test-input
This listens in port UDP 20000 and convert RTP traffic to osmux
Then, it sends osmux traffic via port UDP 20001
2) in another console, run ./osmux-test-output
This listens in port UDP 20001 and convert osmux to RTP traffic
Then, it sends RTP traffic to UDP port 20002
3) in another console run, nc -u nc -u -l -p 20002
This is the sink, just to avoid ICMP destination unreachable messages
Now you can run replay UDP traffic from one pcap trace that contains
RTP traffic with this tool:
http://1984.lsi.us.es/git/pcap-inject/
Example of command line invocation:
./traffic-inject /home/pablo/rtp-nanobts-2-phones-amr.pcap udp 20000
You can run wireshark in the loopback to make sure osmux is getting back
the traces looking like the original.
The tests also generate output files in AMR that you can validate via
mplayer: /tmp/output.amr and /tmp/input.amr respectively. This is to
make sure there are no reordering or problems of any sort.
This patch removes osmo_ipa_recv_msg, it performs two syscall invocations
and it's stream generic. Now we use the specific receival function
we want to use (no matter if stream or datagram based) and then we
call osmo_ipa_process_msg to check that the IPA message correct.
This adds the possibility to specify the variant of the channel.
This was discussed during the osmocom workshop. Harald wanted a way
to say if the channel is using TCP, UDP, DADHDI and so on.
This patch splits osmo_rtp_parse in two functions:
osmo_rtp_get_hdr
osmo_rtp_get_payload
So we can validate corrent RTP header to access its fields. Then,
obtain the payload.
