ANOTHER case of a developer having ignored licenses when importing code.

cron.  When ISC cron 5.0 is out the integration will be even tighter.
Also rename /var/cron/{allow,deny} -> /var/cron/cron.{allow,deny}
for consistency with POSIX and at.{allow,deny} and install an empty
cron.deny file (as we do at.deny) since crontab will require this
in the near future for POSIX compliance.
After a "make build" you can update your system as follows:
# mv /var/at/* /var/cron
# mv /var/cron/jobs /var/cron/atjobs
# mv /var/cron.allow /var/cron/cron.allow
# mv /var/cron.deny /var/cron/cron.deny
# rm -rf /var/at
# kill `cat /var/run/cron.pid` ; cron

Fix up default route selection by
a) Forcing user to explicitly chose 'dhcp' as a mechanism for
specifying a default route, rather than guessing based on one or more
interfaces being configured by dhcp.
b) If the user specified default route does not work, re-present the
existing default route rather than losing it.
c) Move default route selection to after nameserver activation so the
user can specify a hostname as the default route.
Change /etc/netstart so that /etc/mygate wins if a default route was
already specified (i.e. by dhcp).

of the n'th (n>1) file fails, the previous ones get removed before exit(1)

dhclient needs this to validate old (but valid) leases in
/var/db/dhclient.leases in case it needs to fall back to such a
lease.  (the dhcp server can be down or not responding)

Also fix a signed vs. unsigned issue while I am at it.

doesn't blow up.  This is a hack but is better than compiling sha1.c
with -O0 on sparc64.  From NetBSD (mrg).
