Add functions to pass struct osmo_sockaddr to the
osmo_sockaddr_str_{to,from}* API directly.
So far the interface to osmo_sockaddr_str_ is:
osmo_sockaddr_str_from_sockaddr(&my_sa_str, &my_osa->u.sas);
I'm working a lot with osmo_sockaddr at the moment, and the cumulated
time of forgetting to add 'u.sas' and having another compilation cycle
because of those is justifying this additional API.

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/.
