machdep.c: Changed printf's a little and call vfs_unmountall() if the sync was successful. cd9660_vfsops.c, ffs_vfsops.c, nfs_vfsops.c, lfs_vfsops.c: Allow dismount of root FS. It is now disallowed at a higher level. vfs_conf.c: Removed unused rootfs global. vfs_subr.c: Added new routines vfs_unmountall and vfs_unmountroot. Filesystems are now dismounted if the machine is properly rebooted. ffs_vfsops.c: Toggle clean bit at the appropriate places. Print warning if an unclean FS is mounted. ffs_vfsops.c, lfs_vfsops.c: Fix bug in selecting proper flags for VOP_CLOSE(). vfs_syscalls.c: Disallow dismounting root FS via umount syscall.
