I've added WebNFS support (RFCs 2054 and 2055) to the kernel NFS code
and the mountd. See the specs and the exports(5) manual page for
details. Not many people might be able to test it yet, but tell
me if you have problems with it.

IMPORTANT: since this change included extending the export_args
structure and thus the mount structure in <sys//mount.h>, you should
do 'make includes' in /usr/src/sys and then recompile /sbin/mount*
before booting a new kernel, even if you're not using NFS at all.
