Major rcctl(8) rewrite to simplify it and add new features. It can now
configure "user" and "timeout". Committing now because there's been no
release yet including rcctl(8) so it's easier to modify its usage.

Usage extended (*retaining full backward compatibility for now*) to:
rcctl set|get|getdef foobar [flags|user|timeout|status]

The followings will be dropped soon but not right now to give people
time to adjust:
rcctl enable sshd flags	# 'enable' takes no flags, use 'rcctl set ...'
rcctl status sshd	# use 'rcctl get sshd [flags|status|timeout|user]'
rcctl default sshd	# use 'rcctl getdef sshd [flags|status|timeout|user]'
rcctl status		# use 'rcctl getall'

Man page changes will come soon. Make sure you have an up-to-date rc.subr.
