It allows easy verification that timing is correct and makes it easier
to debug time related race conditions.

By using fake own-controlled time we get two benefits:
* Test doesn't take 9 seconds to run anymore
* More fine-grade control of different events happening (and associated
race conditions).

If messages are sent using osmo_stream_cli_send() while the stream
is still (re)connecting, they won't have a chance to be sent until the
stream is connected, and hence they are queued until
CONNECTING->CONNECTED is done. However, at that time
(osmo_stream_cli_fd_cb), the WRITE flag was dropped unconditionally,
which meant already queued packets didn't have the opportunity to be
sent by the same callback until first message is enqueued and WRITE flag
is set (again by osmo_stream_cli_send()).
Let's make them be sent as soon as possible once the connection is
available.

The header of an AMR header payload is 2 bytes long. At the moment we
use just a constant of 2 when we refer to the header length, but we have a
struct amr_hdr defined. Lets use sizeof(struct amr_hdr) to make it more
clear that we are refering to the header length.

This supposed to be variant of osmo_stream_cli_open() with explicit
control over reconnection logic but it's plain broken: doxygen docs
contradict the code, actual reconnection logic is affected by timeout
parameter directly which is set in different function.
It seems like we haven't been affected by this so far because we always
use it in auto-reconnection mode which is triggered by default due to
positive reconnection timeout value (5 sec) automatically used in the
absense of explicitly set timeout.
Looking at commit history, this function already been source of
confusion in the past. Instead of trying to fix this mess, let's just
deprecate it entirely and properly document use of
osmo_stream_cli_set_reconnect_timeout() to control reconnection logic.
The only known user is libosmo-sccp which won't use it as of

Fix a symbol lookup error when building a new test on systems where
a previous libosmonetif.so is installed. Symptoms described here in
detail: https://osmocom.org/issues/3812#note-10
-no-install causes libtool to generate output files that link against
libraries in the build tree, instead of linking against the future
installation paths and generating a wrapper script. The wrapper script
should override the library paths, but at least on Debian, it does not
work as it should. Test binaries won't be installed anyway, so we can
safely use -no-install and work around the problem.

osmo_amr_bwe_to_oa() uses an internal buffer with static size to store
intermediate results. The buffer is large enough for any real world
situation, but the check that tests if the result would fit into the
internal buffer is incorrect. It checks if there is enough room for the
existing payload, but does not include the expected growth of the
payload. Eventually the buffer could be overrun by one byte if one would
put a 256 byte long AMR payload.

RFC 3267 describes two different AMR frame formats. Octet Aligned and
Bandwidth efficient mode. In Bandwith efficient mode the padding bits,
which are used to align CMR, TOC and payload on octet boundaries are
saved and the fielda are packed directly one after another.
- Add functions to convert from one mode to the other and vice versa.
- Add function to detect in which mode an AMR frame is encoded.

AMR uses different payload sizes, those sizes are well defined in RFC
3267. Lets add define constants and replace the magic values with the
define constants.
Also correct the value for AMR_FT_SID in amr_ft_to_bytes from 6 to 5
(39bits / 8 = 4.875 bytes ==> 5 byte, see also RFC 3267, chapter 3.6)

Previously stream client and server code were only used in examples
which means regressions could be easily introduced unnoticed until they
trigger bugs in external code which relies on osmo_stream_*()
Fix this by adding basic client-server interaction tests with and
without reconnection.

Previously closing the client did not alter its state, so we might
end-up with a client without any file descriptors, but being in state
STREAM_CLI_STATE_CONNECTED. Fix this inconsistency by setting
appropriate state.
Related issue is that reconnect function, which is always (at least in
the library and examples) called when some problem with the connection
is detected, closed the connection only after checking whether
reconnection is enabled. This might result in another inconsistency
fixed in this patch by moving the check below connection cleanup.
While at it, also move connection close logging to appropriate place:
it's confusing to see logs about connection being closed while in
reality it wasn't even established.

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.
