Linux no longer tries to match the local address with the remote one,
so address_is_local() fails. Try instead to simply see if we can bind
to the explicit address.

If we can't figure out the source address, we have the "fall on our
face" version of myrecvfrom(); make sure its prototype matches. This
handles building on machines where sockaddr_t != int and yet there is
no way to get the source address. This apparently affects at least
one version of Solaris.

Add support for IPv6 in the server and client.
You can force the use of IPv4 or IPv6 only with new
-4 and -6 commandline options, if IPv6 support was compiled in.
