Pau Espin d4c3dc8d59 Move src/*.{c,h} to src/core/
This way we have all libosmocore.so in an own subdir instead of having
lots of files in the parent dir, which also contains subdirs to other
libraries.
This also matches the schema under include/osmocom/.

to work with an osmo_sockaddr.

This will be used by osmocom-bb's "modem" app.

Philipp Maier a13d5662b7 gsm_utils: improve gsm_gsmtime2fn()
The function gsm_gsmtime2fn() uses a hack to account for the truncated
modulo implementation of C/C++. libosmocore offers proven modulo
functions, so lets use OSMO_MOD_FLR() instead. Also arrange the formula
so that it looks more like the one in the spec.

Also add better spec references and a final modulo GSM_MAX_FN to
prevent frame number results that exceed the valid range.

Max 3f79ce8f23 ctrl: add optional port to bind command
So far ctrl interface did not allow to specify port to bind to.
Let's fix this and make it consistent with the way vty bind works.

N. B: the functions which ignore port configured via vty are marked as deprecated,
the sw which uses them should be ported to either newly added ctrl_init_default()
or simplified ctrl_interface_setup()

The similar change for vty interface will be addressed via separate patch series.

Max 23a7d0740c rate_ctr: drop rate estimation code
Drop the code which tried to estimate the value for the next timeframe:
it accumulated error over time which only adds confusion.

N. B: this means that long-term intervals (day, hour) will show the rate of 0 until
corresponding timeframe passes. This matches how other monitoring software [1] behaves.

Vadim Yanitskiy 6db830f316 gsm0808: use new gsm0808_enc_speech_codec[_list]2() API
The motivation behind adding and using the new API is explained in
the preceeding change [1].  Whenever any of the encoding functions
fails to encode either a Speech Codec or a Codec List IE, free()
the msgb and return NULL.

Vadim Yanitskiy 5a51331729 gsm0808: add gsm0808_enc_speech_codec[_list]2()
The problem with most of the existing gsm0808_* functions in this file
is that they assert() too much, assuming that their callers always pass
perfectly valid input parameters.  But this is impossible on practice,
as there can be bugs in complex projects using them, liks osmo-bsc.

It was reported by a customer that a heavily loaded osmo-bsc crashed a
few times, dropping more than 100 sites without network coverage for
a few minutes.  As was revealed during the investigaion, it crashed
due to a failing assert at the end of enc_speech_codec():

  OSMO_ASSERT(sc->cfg == 0);

The problem is that somehow osmo-bsc is passing an unexpected sc->cfg
value to gsm0808_create_ass_compl2(), in particular 0x02, while the
given sc->type value (GSM0808_SCT_HR1) implies that there cannot be
any configuration bits on the wire.

The reason why and under which circumstances this can be happening
is not clear yet, but what we agreed on so far is that the library
API should be enforcing correctness of the input parameters in a
less agressive way, rather than aborting the process without
letting it any chance to recover.

Modify the original gsm0808_enc_speech_codec[_list]() functions, so
that a negative value is returned in case of an error.  Rename them
and add backwards compatibility wrappers, because it's public API.

A separate patch making use of the new API follows next.

Vadim Yanitskiy c2f1ed1dd0 gsm0808: remove over-defensive assert()s for function parameters
I believe the gsm0808_* API is mature enough to avoid assert()ing
pointers accepted via function parameters.  We can assume the caller
never passes NULL, as we do in almost all public API.

Pau Espin c3b904a87d vty: Allow using hex representations in cmd numeric ranges
Ranges can now be specified in hexadecimal notation. In this case, only
hexadecimal values are accepted (prefixed with "0x").

In order to allow using a hexadecimal value as an input argument, the
command must specify the range in hexadecimal form.
This way all existing commands (decimal) won't get an hexadecimal value
unless they are further extended in the future, avoiding hard to notice
breakage due to use of stroul() without using base=0 or even worse,
using atoi() directly (which only understands decimal and provides no
error checking mechanism).

A command argument can be expanded to accept both decimal and hex in a
range by means of specifying both, example:
"mycmd (<0-255>|<0x0-0xff>)".

Daniel Willmann d5150a61fc use_count: Return if uc is NULL
The documentation for osmo_use_count_get_put states the return value is
"Negative on range violations or USE_LIST == NULL, the use_cb()'s
return value, or 0 on success"

However, the code in _osmo_use_count_get_put doesn't check if uc is NULL
- instead it would crash in osmo_use_count_find() where it is dereferenced.
Add a check for uc and return -EINVAL if it is NULL.
