Handle dual-stack vs. two-stack IPv4/IPv6 in multiudpsink better

This patch does the following:
 - Attempts to portably detect if we have a dual-stack system (linux, mac,
winvista)
 - If we do, use that as we used to.
 - Adds a bunch of fixes for dual-stack mode - e.g. you must add v4 address as
v4-mapped v6 addresses on mac (and vista, I think)
 - If not dual-stack capable, fall back to using two sockets. 
 - Add properties for dealing with the extra socket

So on platforms (linux, mostly) where the current implementation works, this
should do the same thing - no changes to the API, etc.

On mac and vista, the API should remain the same, but it should now work.

On older windows, if you want ipv6 support, you need to deal with two sockets,
but most apps won't care, because they're not using the properties anyway.


I think this is a good compromise (unlike the previously proposed patches, this
doesn't change API unconditionally)
