[interface configuration] Preserve flag indicating address was set by quagga.
2006-05-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* connected.c: (connected_add_ipv4,connected_add_ipv6) If the

(that will consequently be removed by connected_withdraw),
then be sure to preserve the ZEBRA_IFC_CONFIGURED flag.
