With this information we can fix this bug and have RFC-compliant one-shot mDNS support in Resolv (as you only want to accept packets from the local network, see #8089).

I'm not sure it is good idea.

The result of getifaddrs() has no one-to-one mapping to the result of
if_nameindex().

Also, if_nameindex() is standardized by POSIX (and RFC 3493) but getifaddrs()
is not standardized.
So it is good to separate the features to be if_nameindex() is usable even on
a platform which doesn't support getifaddrs().
