mainstream-format fstab format

. detect both formats in /etc/rc
	. generate new format in setup
	. obsoletes /etc/fstab.local: everything can go in /etc/fstab
	. put shutdown/reboot/halt and a copy of /usr/adm/wtmp
	  (/etc/wtmp) on root FS so that we can do shutdown checks before
	  mounting /usr
	. new fstab format makes getfsent() and friends work
