EAI_ADDRFAMILY and EAI_NODATA are not in RFC 3493, but are available
and used in many other systems. It is desirable to have at least one
of them in order to distinguish between names that do not resolve and
those that do not have the requested address type. A change to
getaddrinfo() will use EAI_ADDRFAMILY. Both were "#if 0"; re-enable,
conditioned on __BSD_VISIBLE, and update comments. Also add comments
and __BSD_VISIBLE conditional for the last three EAI errors, which
are not in the RFC or POSIX. Note, all of these are available in
NetBSD and OpenBSD, and EAI_ADDRFAMILY and EAI_NODATA are available
in Linux (glibc).
