The function is checking for IP version matching between local and
remote addresses even if only one is needed based on flags. For example,
if user only desired to bind, the remote address should not be
used nor checked.

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

Drop one of the two log lines since it would be a duplicated and anyway
it misses context (return code).

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.

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

The old osmo_sock_init() function allows only either a bind (for a
server socket), or a connect (for a client socket), but not both
together. So there's no way to have a client socket that is bound to a
specific local IP and/or port, which is needed for some use cases.
