NetBSD/usr.sbin/tcpdump/dhcp6.h
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
