accept NUL-terminated strings as required by RFC 2132.
This solution is not perfect as it removes the ability to send
NUL-terminated host-name options which may be required by some broken
servers. Given the current lack of an existance proof of such servers
and the fact that servers that send NUL-terminated domain names do
exist, this seems like an acceptable compromise. A discussion of these
issues can be found at:

include a space seperated list of domains instead of the domain of the
host. This is supported on too many platforms to break for now so,
remove validation of this option for the moment.
The correct solution longer term is to implement RFC 3397 support and
then treat domain-name options containing space seperated lists of
domains as domain-search options for backwards compatability.

Add a -b option to background immediatly.
Add support for 802.11 routing messages to "instantly" renegotiate
at lease when we associate with a new network.

Enable dhclient to poll the interface state and send only
requests if the interface has an active link. This is a
great benefit if you often change networks with your laptop
and you do not like to kill/restart dhclient all the time.
Changes are automatically detected and the link is refreshed.
The change allows us to start dhclient in background mode
while the network cable is not plugged in.
To control the polling interval, the option -i has been
introduced. It takes seconds as parameter, the minimum is
one second, the default is five seconds.
Polling is done in seconds, not microseconds, because dhclient
does internally work with timeouts in seconds.
This change will be part of the next major ISC-dhcpd release.
Tested by: bms, imp, and many many others.

src/contrib/isc-dhcp/includes/minires/resolv.h has a 'extern' definition
but it makes an error when linking crunched binary just like this:
dhclient.lo: In function `MRres_nquery':
dhclient.lo(.text+0x2dcce): undefined reference to `__h_errno_set'
dhclient.lo(.text+0x2dd5b): undefined reference to `__h_errno_set'
dhclient.lo: In function `MRres_nquerydomain':
dhclient.lo(.text+0x2de53): undefined reference to `__h_errno_set'
The author understands this will be a problem (see comments in resolv.h).
Murray said that the author will fix this, but as a temporary solution,
modifying the source code and not to use __h_errno_set.
BTW, I'm sorry that previous commitlog in src/sbin/dhclient/Makefile should
read "Found by:" instead of "Confirmed by"; I just found that rev 1.15
has a typo so fixed.
Tested on: ushi.jp.FreeBSD.org with today's 5-current source code.

configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.
= Hesiod has been added to libc (see hesiod(3)).
= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).
= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr
= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

Of course this is a bug in that the dhclient script will not work properly
if one has a local / and an NFS mounted /usr and needs to obtain its IP
address via DHCP before being able to mount /usr.
