This is basically a successor of gsm0808_create_sapi_reject(), but
instead of hard-coding GSM0808_CAUSE_BSS_NOT_EQUIPPED, it allows
the caller to specify a cause value to be used. The old function
is now deprecated and should not be used.

Some systmes (like the ones available in OBS) don't support creating
SCTP sockets, so we need to skip those tests there.

The flag was added recently in cd133316cf,
and it is causing issues while running unit tests in environement like
OBS where probably there's no non-loopback address configured.

The function is improved to support AF_INET:v4->v4, AF_INET6:v6->v6 and
AF_UNSPEC:v4+v6->v4+v6.
Unit tests for the function are added to make sure function behaves
correctly in several scenarios.

Address resolution is done first and once we have the information, it
proceeds to create the socket. This separation in steps will help when
adding support for IPv6+IPv4 sets, where AF_UNSPEC is passed and created
socket needs to be AF_INET6 in order to handle addr of both versions.

It's more convenient to use i in the outer loop, and j, k, etc.
in the inner loops. Otherwise it looks a bit confusing.

Shared code might be used by applications that have no vty, so sched
can't be initialized, do not assert and break everything in this case, a
warning should suffice.

When dealing with IPv4 and IPv6 address, the struct sockaddr
allows to hold IPv4 and IPv6.
However even when struct sockaddr is being used, a cast to the
IPv4 or IPv6 family must happen. To work around this additional code,
use a union for the most common types.

Process willing to support this kind of configuration through VTY simply
need to call "osmo_sched_vty_init(tall_ctx);" during startup to register
the commands.
For multithreaded processes, new threads willing to get their
cpu-affinity mask according to VTY config should call
osmo_sched_vty_apply_localthread() (potentially after
setting the thread name through pthread_setname_np()).

configure flag required to enable this: --enable-neon
Although autodetection according to __ARM_NEON would work because this
is only defined if the fpu is neon neon-fp16 neon-vfpv3 neon-vfpv4
neon-fp-armv8 crypto-neon-fp-armv8 doing that would lead to a unknown
performance impact, so it needs to be enabled manually.
Speedup is about ~1.3-1.5 on a unspecified single core Cortex A9. This
requires handling a special case for RACH with len 14 which is far too
short for neon and would actually incur a performance penalty of 25%.

osmo_sock_init2 abstract two calls of getaddrinfo into one.
While there aren't problems with AF_INET or AF_INET6. When using
AF_UNSPEC there are corner cases when this fails. E.g. calling
local_host with "" and remote_host with an IPv6 only address results in
setting up a local socket with AF_INET while trying to connect from there towards
AF_INET6 will most likely fail.
To prevent such cases with AF_UNSPEC, search prio calling any syscalls if local and remote site
supports AF_INET or AF_INET6. In case both supported, prefer AF_INET6

Add bssgp_ns_send callback() to set the transmission path into the
NS library. This allows to use the Gb implementation with
the old NS and the new upcoming NS implementation.
Users of the old NS implementation don't have to set the callback as
the default is the old NS implementation.
Only users of the new NS implementation need to set the callback and
the callback data.

When I wrote the new I.460 mux + demux code, I failed to realize that
* bit numbers in relevant ITU specs start with 1 as MSB ... 8 as LSB
* sub-slot 0 is bits 1+2, i.e. the two MSBs of a byte
* bit-ordering within each sub-slot is also MSB first
As a result, the code and test data was broken.

When calling a user-provided call-back function for the i460 mux
or demux, always pass a pointer to the osmo_i460_subchan the callback
relates to. This way, the user can walk the i460 data structures
to obtain information about which mux/demux instances is calling.

There is no way for the API user to know if the TX queue of the
multiplexer runs empty. However, this is criticil since an empty TX
queue will cause dropout of a TRAU frame, which can have quite severe
effects to the receiving end. Lets add a callback that allows the APU
user to insert appropiate idle frames or silent frames into the queue
before it runs empty.

Without this patch, for instance having a range 0-ULONG_MAX would match
if someones types value -3, which would be converted to unsigned but
that's clearly what is expected here from user point of view.

When a subchannel is deleted or created the initalization mainly
consists of a memset over the wohle subchannel struct a message buffer
initailization.
However, when we delete a subchannel we also must take of the resetting
of the related struct. Currently this is done with a memest.
Unfortunately this creates not only a memory leak (there might be still
items in the multiplexer tx queue) but also it makes the application
crash when the message buffer is used the next time since the llist_head
of the tx queue looses its initialization.
Lets fix the memory leak problem and the message buffer problem and put
the reset functionality in a single place.
