Establish which ipv4/ipv6 socket addresses to open

[lodejard]

Assumption is localhost should be ipv4+ipv6 loopback, numeric addresses should be that address in ipv4 or ipv6, and any other name including + and * should be ipv4+ipv6 any ip

This is a super old bug but it was in the alpha4 milestone, so moving to RC1 to reevaluate.

this and aspnet/Announcements#80 have the milestone as rc1/rc2, but based on the description of aspnet/Announcements#80, should they be beta8 instead / in addition?

@Tratcher ?

Updated. The initial change was in beta8: f0137b7

var remoteIp = context.Connection.RemoteIpAddress.ToString();
why it is always null after I upgrade it from beta7 to beta8? Thank you!

I Used asp.net 5, VS beta8 and dnx beta8 get null remote ip, when I use dnx beta7,it is ok to get the remote ip address,I am confused.
