david d90b7b15a7 Make a new function called resolve_all in tcpip.cc, which is like ...

resolve except that it returns all resolved addresses. Use this new
function to resolve IPv4 addresses instead of gethostbyname in
TargetGroup.cc. The gethostbyname code assumed that only IPv4 addresses
would be returned. If the resolver returned IPv6 addresses, TargetGroup
would blindly copy the first four bytes of the IPv6 address into the
IPv4 struct. This was first reported by Mats Erik Andersson at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=584301; he also
suggested the fix.
