The dev/user in general is only interested about one side of the stream
when looking at the code. Since the stream.c file is tarting to be quite
large/bloated, this patch splits its content into stream_cli.c and
stream_srv.c to make it easier to improve/extend and review.
Keep common code between cli and srv in stream.c, and add a private header
to contain references to it.

The output and input paths are totally independent, they share no code
or structures holding state. They can be operated totally independently.
Hence, let's split the code into separate file since when someone looks
at the osmux code one is really looking specifically at Tx or Rx side,
but not at both sides.
Moreover, the "input" and "output" concepts have always been a bit
difficult to understand (would have been better calling them "src" and
"sink" instead), which adds more confusion when trying to find the
relevant part of code.

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.

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.

The recently-introduced dependency to libosmogsm symbols needed
some explicit addition of linker flags to avoid user applications
to fail linking with
/usr/bin/ld: /usr/local/lib/libosmonetif.so: undefined reference to `ipa_ccm_id_resp_parse'

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.

Wih this change, osmo_stream_ client and server API can be used not only
for TCP but also for SCTP. The latter is needed in SIGTRAN ad Iuh
applications, for example.
I have added two new interfaces to add and to delete circuits from osmux input
handles. The client application needs to be adapted to use them otherwise it
will break. That's why I'm making this library release incompatible with the
previous generation.
When libosmo-abis is installed in a distinct prefix, the build failed
with non-found headers, for example:
../../src/rs232.c:38:35: fatal error: osmocom/abis/e1_input.h: No such file or directory
#include <osmocom/abis/e1_input.h>
This patch adds the initial RTP support for libosmo-netif, it's based
on Harald's RTP support available in openBSC.
I have also added a couple of example to show how our new channel
infrastructure interacts with the RTP layer.

This patch adds the generic channel infrastructure that allows to
create channel of different types. Each channel has their own
configuration functions.
struct osmo_chan *chan;
chan = osmo_chan_create(tall_example, CHAN_ABIS_IPA_SERVER);
...
/* specific configuration functions per supported channel. */
osmo_chan_abis_ipa_server_set_cb_signalmsg(chan, signal_msg_cb);
osmo_chan_abis_ipa_unit_add(chan, 1801, 0);
/* open channel. */
osmo_chan_open(chan);
The input path requires a callback to be registered. The output path
is handled through:
int osmo_chan_enqueue(struct osmo_chan *c, struct msgb *msg);
The msg->dst must be set (it can be taken from the original message
to route one reply).
This patch also adds A-bis IPA server support. It has been tested with
e1inp_ipa_bsc_test available in libosmo-abis.
This patch adds IPA helper function that can be use on top of stream
sockets.
The current API is just a copy and paste from libosmo-abis, it will
change in follow up patches to improve it.
