[interface configuration] Try to avoid losing address info after shutdown.
2006-05-21 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * if.h: (struct connected) Document the meaning of the ZEBRA_IFC_REAL and ZEBRA_IFC_CONFIGURED flags. * connected.c: (connected_withdraw) Do not delete the connected address if the ZEBRA_IFC_CONFIGURED flag is set. (connected_add_ipv4,connected_add_ipv6) Before calling connected_withdraw, unset the ZEBRA_IFC_CONFIGURED flag on the superseded connected structure.
