Modified Files:
	syssrc/sys/netinet [netbsd-1-5]: ip_icmp.c udp_usrreq.c

Log Message:
Pull up UDP, ICMP fixes:

 - Drop packet, increment udps_badlen if the udp header length field
   reports a size smaller than the udp header; defends against bogus
   packets seen by by Assar Westerlund.

 - allow icmp_error() to work when icmpreturndatabytes is sufficiently
   large that the icmp error message doesn't fit in a header mbuf.

 - defend against mbuf chains shorter than their contained ip->ip_len.

Joint work of myself, itojun, and assar
