Enabling sender_dry_event in SCTP_FLAGS breaks reliable delivery of DATA
chunks to the scoket user on Linux. Let's avoid enabling that, while
still enabling various other interesting events.
See https://bugzilla.redhat.com/show_bug.cgi?id=1442784 for all related
details.

We were using the wrong variable when setting the SCTP_NODELAY,
resulting in the setsoctkopt() fialing.

'struct ipaccess_unit' is defined in libosmocore/gsm/ipa.h, we shouldn't
re-define it here. This entire IPA code duplication accross multiple
libraries and programs is a big mess.

So far we seem to assume that the accept_cb does all handling of socket
fd cleanup. However, there are cases where there is no accept_cb set,
the accept_cb returns error, or an earlier sctp_sock_activate_events()
or the activation of non-blocking mode fails.
For those cases, close the socket and return an error code.

In a659590e29 we fixed endianness issues
with the Stream ID field, but at the same time mistook the PPID field
for 16bits. In reality it is 32bits, and hence our 'htons' is rendering
wrong PPID values.

Using this function, the user can configure if sockets related to the
respective stream client or server should have the NODELAY socket
option set in order to avoid Nagle algorithm or related algorithms
that may introduce packet delay on the transmitter side.

In their infinite wisdom, the inventors of SCTP designed an API (the
sockets API described in RFC6458), where some members are in host byte
order (like the stream identifier), while other members are in network
byte order (like the PPID).
Let's handle this properly (we assumed both are network byte order), and
also use 16-bit htons/ntohs fo the PPID, rather than htonl/ntohl.

* when using osmo_*_destroy(), always call *_close() internally to
make sure we don't free memory holding references to sockets that are
still open
* when closing the socket, always make sure to set the fd to -1 in all
cases, to avoid attempts to avoid later close() on a new file using
the same fd number as the socket closed previously.

during osmo_*_set_addr(), we must make sure to talloc_free() any old
address before copying in the new address. Not all functions did this,
and those that did implemented it manually. Let's use
osmo_talloc_replace_string() which is exactly intended for this case.

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.
Change-Id: I41314bad4a9f44e8a61b9d2ba33d1a76b25bd145
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.

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.

Explicitly set AC_CONFIG_AUX_DIR.
To reproduce the error avoided by this patch:
rm install-sh # in case it was already generated.
touch ../install-sh # yes, outside this source tree
autoreconf -fi
This will produce an error like
...
configure.ac:16: error: required file '../ltmain.sh' not found
configure.ac:5: installing '../missing'
src/Makefile.am: installing '../depcomp'
autoreconf: automake failed with exit status: 1

Introduce a local #define to disable the real-time constraint from osmux-test.
It would make sense to remove this completely, but in case anyone may be
interested in the timing on a specific platform, I've just #defined it away.
The real-time constraint to pass or fail the test is a bad idea in terms of our
build server. Whenever the server is loaded, the tests will fail for no reason,
like here: https://gerrit.osmocom.org/474
The real time to calculate is highly dependent also on the hardware platform.
The arbitrarity of the time constraint is sort of proven by dd24cdd95f
which simply doubles the time to pass the test.

Use this function in osmux_batch_del_circuit() since msgs are stored in a list
per circuit. After the circuit is free()d the msgs are lost.
Before this patch any messages enqueued inside a batch when the circiut is
deleted were leaking.
