Brian Somers 3edeb0c69e Support client side DNS server negotiation, disabled
and denied by default (POLA).

o Remove ``enable'' msext.  Now, doing a ``set nbns'' will
  automatically enable a NBNS ACK/NAK rather than a REJ.
o Add accept|disable|deny|enable dns.  If we ``accept'',
  we'll tell the peer what our nameservers are (if he asks).
  The values in resolv.conf can be overridden with the
  ``set dns'' command.  If we ``enable'', we'll REQ using
  our resolv.conf entries, and any NAKs are written back to
  resolv.conf.
o Remove ``show msext'' and show the relevent IP numbers in
  ``show ipcp''.
