According to sockettest.c, that function does work for "::", and
examining the macro that it uses (from /usr/include/netinet/in.h) I see
that it is doing exactly what we need (checks all 4 uint32s in the
address against 0). So ACK.

(Nice! We should have been using that all along, instead of parsing out
"::" and calling virSocketAddrEqual())
