- 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
of NFS packets over TCP. Upgrade to 3.0.4 while at it. 3.0.4 fixes previous
fix made to util.c too; 'official' fix applied instead (very minor difference).
Fixes to be sent to maintainers RSN.
