When someone is modifying a given library there's no need to be looking
at a common file contains tons of lines from different libraries.
Furthermore, this removes the need of "nobase" autofoo prefix, hence
following the usual directive of having one Makefile per directory.

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/.

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.

The function gsm_gsmtime2fn(), which is used to compute a frame number
value from given starting time values T1, T2 and T3 has no unit test.
Due to to the modulo that is used the computation can be a bit tricky.
Lets add a unit-test to make sure the function works as expected.

C/C++ only implements a so called "truncated modulo" function. Lets also
add a floored and an euclidian modulo function to be more complete.

Don't attempt to build osmo-stat-dummy, unless ENABLE_UTILITIES is set.
We check for this in utils/Makefile.am too.
Fix for currently failing master-osmo-ccid-firmware job, at
cross-compiling libosmocore:
make[3]: *** No rule to make target '../../src/vty/libosmovty.la', needed by 'osmo-stat-dummy'. Stop.

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.

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.

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.

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.

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.

This assert can be dropped because the switch statement above does
not leave any sc->type >= 0x0f for type_extended == false.

We've started to encapsulate a varieth of ISDN related formats
as sub-types to GSMTAP_TYPE_E1T1 for quite some time. Let's add
some more formats, such as V5EF, V.110, V.120, X.75 and H.221
For the HDLC based V5EF, V.110, V.120 and X.75 the payload format is
clear. For V.110 and H.221 we will need to specify how the actual
payload looks like.

The newly-introdiced pragma to disable strict-prototypes checking works
in C, but creates a -Werror=pragmas error in C++ code:
In file included from osmo-trx.cpp:45:
/build/deps/install/stow/libosmocore/include/osmocom/vty/logging.h:10:32: error: option
‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ [-Werror=pragmas]
#pragma GCC diagnostic ignored "-Wstrict-prototypes"
So let's also suppress those errors for that one line of code...

Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea0). However,
its declaration in C file didn't contain "(void)", which meant the
number of parameters is undefined and thus compiler doesn't complain.
However, in recent Change-Id I84fd99442d0cc400fa562fa33623c142649230e2
we changed the declaration to '(void)' to allow building with
-Wstrict-prototypes. This caused downstream build-failures of osmo-mgw (1.4.0)
and osmo-e1-recorder (master).
So let's make one very small-scoped exception here.

Unfortunately "-std=c99" is not sufficient to make gcc ignore code that
uses constructs of earlier C standards, which were abandoned in C99.

Those are similar to existing *msgb_alloc*() functions but allows
to change the size of destination msgb provided it fits the
