People like to do RFC violating things with the domain-name option and
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.

Fix an off by one error when we limit append/prepend text sizes based on our
internal buffer sizes.

When we 'append', assume we're appending to text. Some MS dhcp servers will
give us a string with the length including the trailing NUL. when we 'append
domain-name', we get something like "search x.y\000 z" in resolv.conf :(

Defer state change on disassociate to avoid unnecessarily dropping the
lease: track the current bssid and if it changes (as reported in an
assoc/reassoc) event only then kick the state machine. This gives us
immediate response when roaming but otherwise causes us to fallback on
the normal state machine.

Send client identifier unconditionally. My ancient D-Link router response
with NACK if I don't set it. Setting 'option dhcp-client-identifier' is
alternative but it is inconvenient because I have to keep the list of
all MAC addresses. As bin/94743 pointed out, it is always sent from
Windows clients and I found Mac OS X does the same.
