[M] Change in libosmocore[master]: add new osmo_sockaddr_from_str_and_uint() function

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/35085?usp=email ) Change subject: add new osmo_sockaddr_from_str_and_uint() function ...................................................................... add new osmo_sockaddr_from_str_and_uint() function The function is basically a shortcut for getaddrinfo with storing the output data into our 'struct osmo_sockaddr'.
