jails and loopback IPs

Jails on DragonFly can now route to loopback addresses (i.e. 127.0.0.1).  Because of this, they can work like shared IPs and the jail can connect to the host.

I think this means that you no longer have to bind jail services to specific IPs as you did previously.  Don’t quote me on that; I’ve run few jails in my life.

Update: I should have linked this too: the sysctl jail.defaults.allow_listen_override that makes it easier in the host system too.
