dhcpd: fix -Wunused-but-set-variable warning

ok krw@

Support looking up ethernet addresses in /etc/ethers at dhcpd startup time.
If the lookup fails it falls back to parsing the ethernet address normally.
ok krw@

Bring parse_warn() into the log.[ch] 21st century and adopt the "^"
placement logic from dhclient.

Eliminate pointless'%m' (a.k.a. hand rolled strerror()) by using fatal() and
log_warn(). Zap a couple of explicit 'syslog()' calls.

Adjust some long lines.

Switch from old errwarn.c logging to shiny new log.[ch].

ok benno@

Move parse_warning() into parse.c to prepare to replace errwarn.c
with standard daemon log.[ch].

ok mpi@

Pull in <time.h> for one or more of gmtime, strftime, strptime, time,
timegm, and tzset

ok deraadt@

Eliminate #include inside *.h files and include only needed headers in
each *.c file.

Inspired by mention of header silliness by Edgar Pettijohn and mmcc@
on tech@.

Actually use default-lease-time, max-lease-time, bootp-lease-length
specified in dhcpd.conf. Broken in -r1.18.

Problem noted by Arne on bugs@, identical fix independently developed
by Serguey Parkho

Tweak parsing so that hostnames starting with 0-9 are accepted.

Reported long ago by matthieu@. Also Jacob Berkman via the lists.

Tests and suggestions from Jacob and Matthieu.

Two 'break;'s in a row seems excessive.

Stop pretending we still support FDDI or token ring hardware types.

Replace hand-rolled date printing/parsing code with strftime()/strptime().
Use timegm() because all the dates are in UTC and the 'standard'
routines can't handle the truth.

Replace hand-rolled date printing/parsing code with strftime()/strptime().
Use timegm() because all the dates are in UTC and the 'standard'
routines can't handle the truth.

Remove some 'time_t is 32bits' assumptions.

Print 'UTC' at the end of dates in the leases file, rather than
mentioning that all dates are UTC in a comment at the top of the
file.

Feedback and suggestions from guenther@, kettenis@, otto@, tedu@,
deraadt@.
