We should have doxygen documentation for all libosmo-* APIs.
libosmo-netif is currently devoid of any API docs. Let's start with the
stream and datagram socket related functions.

without setting the BSC_FD_* flags prior to reconnection, the re-connect
would happen silently and the client program would not be notified via the
connect_cb().
Change-Id: Iaf8ec8662cf83476eee1b76fa41dc57f063f0ad3
In case the application is using the read-callback and a read returns 0,
then the application itself would want to trigger the reconnect. This
is different from the osmo_stream_cli_recv() case where the reconnect
can be handled internally to the library.

if osmo_stream_cli_destroy() is called while the reconnect timer is
running, we would end up in a crash.
Change-Id: If6597130f472f1e2b8d9682002250ecd54675bb0
We use the magic value '-1' in case the file descriptor is not yet
initialized. If somebody calls osmo_stream_*_close() before this
changes, we used to crash. Let's check for this and avoid a crash.
Also, after close let's change the fd to -1 again to mark the fd
invalidity.

The reconnect behavior was likely broken in commit
de3f57a8293a5b39435d6f283da23e0172bad8bb
If the user requests a re-connect, we should start it. Not only in case
the connection drops later, but also if the initial connection itself
fails.
Change-Id: I817e026404cbd9145cae2ce90bc57a1db1d2e12b
osmo_sock_init() never returns -1 + errno EINPROGRESS. It will return a
positive fd in case the connect operation is in progress. Therefore,
the related code in osmo_stream_cli_open2() was impossible to execute.

Fixes: Coverity CID 57861
When the setsockopt() in sctp_sock_activate_events() indicates an error,
let's print an error message in the log about this.

So far, when the first connection attempt failed in
osmo_stream_cli_open(), we returned a terminal errro without any
re-connection attempts. While this may be useful in some cases, our
general idea of the stream client logic is to handle the reconnection
attempts insid the library. We introduce a new osmo_stream_cli_open2()
function while keping the old behavior for backwards compatibility.
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.
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.
Add new functions:
osmo_stream_server_link_get_data
osmo_stream_server_conn_get_data
osmo_stream_client_conn_get_data
To obtain private data from osmo_stream_* handlers.
This patch also introduces missing osmo_stream_server_conn_set_data.
