- Don't complain when debouncing dhclient startup.
- Fix buffer handling in reveive_packet(). This fixes infinite cpu
eating loops and probably some crashes.
- Spell if_defaultroute route correctly in dhclient-script so we
are allowed to change the default route.
- Document dhclient -b.
- Treat reassociation like association.
- Do not force server-name to be a valid domain name.
- Handle servers that send NUL-terminated host-name options.
