Fix several Linux-related problems found during last workshop:
1) rpki.https.http_listener() didn't handle .bind() failure properly,
which left asyncore in a weird state.
2) On Linux, sockaddr.getaddr() can return duplicate records. This is
insane, but the maintainers appear to consider this a feature, so
we have to suppress it.
3) Linux's support for IPv4 mapped addresses in IPv6 is so whacked
that it's impossible to tell whether a socket.bind() failure is
real or an artifact of Linux's whacked API without checking the
value of a magic sysctl. This is just too much fun for words, so
IPv6 listeners are now disabled by default on Linux; feel free to
turn them on yourself, but don't blame me if they
