- Remove the removable_interfaces variable. /etc/pccard_ether will

now run on any interface.
- Add a new ifconfig_<ifn> keyword, NOAUTO which prevents configuration
  of an interface at boot or via /etc/pccard_ether.  This allows
  /etc/rc.d/netif to be used to start and stop an interface on a purely
  manual basis.  The decision to affect pccard_ether may be revisited at
  a later date.

Requested by:	imp, gallatin (removable_interfaces)
Discussed with:	sam, Randy Bush (NOAUTO)
