bsdinstall: Add new Auto option to netconfig interface selection dialog
This changes the OK / Cancel buttons into Auto / Manual / Cancel, with Auto being the default. Manual behaves like OK used to, i.e. presents a series of dialogs asking exactly how to configure the interface, and Cancel is unchanged, exiting with exit code 1. Auto will attempt to configure IPv4+DHCP and IPv6+SLAAC with no interaction, failing only if neither can be configured, thereby supporting all of IPv4-only, IPv6-only and dual-stack environments. If at least one DNS server is provided, it will also skip asking for DNS settings, otherwise it will act like Manual mode for the purposes of DNS settings and prompt. For a standard dual-stack environment this cuts down the number of netconfig dialogs from 6 (interface, IPv4, DHCP, IPv6, SLAAC, DNS) to just the first one.
