[bgpd] bug #210: Enable crucial VPNv4 code which was disabled

2006-05-04 Paul Jakma <paul.jakma@sun.com>

	* (general) VPNv4 fixes. Certain VPNv4 code was not enabled.
	  See bug #210.
	* bgp_attr.{c,h}: (bgp_packet_{withdraw,attribute}) Tag should be
	  u_char really.
	* bgp_packet.c: (bgp_{update,withdraw}_packet) Enable some
	  VPNv4 code which inexplicably was ifdef'd out. comments from
	  a tester on IRC suggest this fixes bug #210.
