David Gibson 4e08d9b9c6 treewide: Use sa_family_t for address family variables
Sometimes we use sa_family_t for variables and parameters containing a
socket address family, other times we use a plain int.  Since sa_family_t
is what's actually used in struct sockaddr and friends, standardise on
that.
