Remove unsupported "dev" option from comments of mntopts.h.

Remove MNT_NODEV mount option. In RELENG_6, MNT_NODEV was a no-op.
The presence of MNT_NODEV was confusing the am-utils autoconf scripts.

- Make size parameter to build_iovec() a size_t, not an int
- Add build_iovec_argf() helper function, for help converting old
mount options which used the mount_argf() function for the mount() syscall.

Discussed with: phk

Use MOPT_END in favor of MOPT_NULL, which better describes the purporse
of the macro.

Add a handy macro to represent null mount option, MOPT_NULL, and make
use of the macro in sbin/mount*'s, by replacing:

mopts[] = {
MOPT_STDOPTS,
{ NULL }
}

With:
mopts[] = {
MOPT_STDOPTS,
MOPT_NULL
}

This change will help to reduce the situation that we don't explicitly
initialize "struct mntopt"'s. It should not contribute to any
functional/logical changes as far as I can tell.

Revert last change. It doesn't break mount(8) reporting
but allows a "nodev" in /etc/fstab, etc.

Fix the mount(8) status reporting, now that MNT_NODEV is a no-op (zero).

Teach mount(8) about MNT_ACLS for the purposes of mount options and
mount option printing.

Introduce support for Mandatory Access Control and extensible
kernel access control.

Teach mount(8) to understand the MNT_MULTILABEL flag, which is used
to determine whether a file system operates with individual per-vnode
labels, or treats the entire file system as a single object with a
single (mount) label. The behavior here will probably evolve some
now that nmount(2) is available and can more flexibly support mount
options.

Add the snapshot option to mount_ufs.

mount* fixes from Martin Blapp <mb@imp.ch>:

Made mount more userfriendly (bad slashes are now filtered out)
and we remove in mount_nfs trailing slashes if there are any.

Fixed mount_xxx binarys to resolve with realpath(3)
the mountpoint.

Translate the deprecated nfs-syntax with '@' to ':' .
The ':' syntax has now precedence, but '@' still works.
Notify the user that the '@' syntax should not be used.

Add an option to the way UFS works dependent on the SUID bit of directories
This changes makes things a whole lot simpler on systems running as
fileservers for PCs and MACS. to enable the new code you must
1/ enable option SUIDDIR on the kernel.
2/ mount the filesystem with option suiddir.
hopefully this makes it difficult enough for people to
do this accidentally.
see the new chmod(2) man page for detailed info.

Add noclusterr and noclusterw options. The noclusterr and noclusterw
disable clustered read and write, respectively.

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!

Implemented user side of "noatime" mount option. This option disables
the file access time update on reads and can be useful in reducing
filesystem overhead in cases where the access time is not important (like
Usenet news spools).

The changes for adding the "noauto" option were mostly wrong. MNT_NOAUTO
is a kernel flag, and the kernel definately doesn't need to know about
it.

Add a "noauto" flag so that you can do things like prevent your system
from not coming up multiuser just because you have a CD mount in fstab
but no CD in the drive.

Fix force flag: It is not a "negative" flag. Add MNT_FORCE to the acceptable
options for UFS (which fixes another bug).

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!)
