When a user reports a memory leak with a talloc report, this script is
useful to quickly get a handle of what is being leaked. The alternative
is eyeballing the talloc report for a very long time.

Let libosmocore-dev depend on libmnl-dev, as we build the debian package
without --disable-libmnl and so libosmocore.pc lists libmnl in requires.
This patch should fix the following error when trying to build any
debien package depending on libosmocore-dev:
Package 'libmnl', required by 'libosmocore', not found
A similar change in the rpm spec is not be needed, as rpm adds depends
from pc files automatically.

netdev.h doesn't expose its use of libmnl publicly. It could actually be
implemented using other subsystems internally, such as ioctl() or other
OS-dependent APIs.
Hence, if --disable-libmnl is used, still make the API available but
make it fail with -ENOTSUP on functionalities which are only implemented
through libmnl so far.

This module provides several operations on network devices
(interfaces), like monitoring changes, setting addresses, routes, link
state, etc.
It also supports managing network interfaces on several different netns
concurrently.
These functionalitites will be used by the tun module included in a
follow-up patch.

There are some parts of libosmogsm which are not really GSM specific,
but rather ISDN bits that were inherited by GSM. This includes the
I.460 multiplex as well as the core LAPD protocol.
Let's move those bits to its own libosmoisdn library, before we add
more ISDN specific bits to the wrong place.
Backwards-compatibility is created by making libosmogsm depend on
libosmoisdn, and by providing wrapper include files for source
compatibility.

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.

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

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.
