Merge from Lite2
- 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!

Add support for filesystem-specific `-o' options, and re-implement the
most common cd9660 and nfs options like God intended them. (It is now
possible to say

mount -o ro,soft,bg,intr there:/foo/bar /foo/bar

again.) This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3). Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.

(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)
