martin fa10c3107d Make tcpdump work with the current pppoe code. 
Will be revisited when a generic PPP sheme is implemented.

wiz 14dbdf5518 Negative exit code cleanup: Replace exit(-x) with exit(x). 
As seen on tech-userlevel.

itojun ca89dc0998 minimize diffs to tcpdump.org tree, even if cosmetic. 
changes include:
- do not chase header if ip/ip6 datagram is framgented, and it is not the
  first fragment
- u_short -> u_int16_t
- buffer boundary checks, including sprintf -> snprintf
- cleanup truncated packet cases
- pull tcpdump.org enhancements/corrections for RIP, IPv6 options, ICMPv6,
  OSPFv3, IPv4 options, BGP

there are a lot of local/conflicting changes.  we'd gradually decrease
# of diffs by synchronizing both ends, and then move to src/dist/tcpdump
and reachover makefile.

enami f93a8a97b8 Parse nfs file handle better on NetBSD. On little endian machine, 
it was completely broken.  On big endian machine, it was detected as SUNOS4
and thus 32bit dev_t isn't handled properly.

XXX: The auto detect code should be integrated more cleverly if possible.
XXX: In addition, it is better if there is a way to specify server os type.

have __attribute__((__packed__)) for align picky arch
(tcpdump.org code has better fix with lots of memcpy, however,
tcpdump.org version needs more verfication).

basically, sync with kame tree.

itojun 058e85bfc6 we shouldn't use "(ip + 1)" to detect intermediate headers (AH/ESP). 
we should use ip_p == IPPROTO_TCP/UDP.

itojun d9bba2ca98 some merge from tcpdump.org code. 
- print-telnet.c: do not print control character
- print-icmp6.c: improve icmp6 node information printing
  (we need to at least meet our kernel code!)
- update dhcp6 printing to 15 draft (14 and 15 are totally incompatible)
- add safeputc() and safeputs() into util.c
