libufs, which only works for Charlie root.
This change reverts the introduction of libufs and moves the
check into the kernel. Since the f_fstypename is the same
for both ufs and ufs2, we check fs_magic for presence of
ufs2 and copy "ufs2" explicitly instead.

getvfsent() in most cases. (The main exception is when /etc/fstab
still hasn't been converted to use a slice for the root device, the
root device is a SCSI device, and the /dev/sd* inode for this device
still hasn't been renamed to /dev/da*.)
something that might refer to the compatability slice rather than the
correct slice entry, try all the possible slice entries first.
This is a compatability hack to deal with the case where the kernel has
correctly mounted the root filesystem out of its slice, but the user
has not updated their /etc/fstab file to reflect this. A diagnostic
is emitted if the mount succeeds, indicating that the file should be
updated.
This is a prelude to fixing the kernel to behave as alluded to above.

- use new getvfsbyname() interface and mount(2) interface
**DANGER WILL ROBINSON!!** You must be running a -current kernel
from within a week or so in order for this to work!
