Switch the default WARNS level for sbin/ to 6.

Submitted by: Ulrich Spörlein

Convert mount_ext2fs to a simple program which passes "-o option" to nmount().

Garbage collect useless variables.

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.

Support mounting ext2fs file systems with -async to the small extent
that ext2fs in the kernel supports async mounts. ext2fs used to
effectively force the -async flag on. -async for ext2fs only gives
async (more precisely, delayed) writes for inode updates, so it is
barely worth using even when it is safe.

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

Don't depend on namespace pollution in sys/mount.h and
include sys/uio.h.

Now that the kernel is able to load modules itself,
remove all the code which was trying to do so.
This code was nasty in several ways, it was hiding
the kernel bug where the kernel was unable to properly
load a module, and it was quitting if it wasn't able
to load the module. The consequence is that an ABI
breakage of the vfsconf API would have broken *every*
mount utility.

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.

Don't refuse to pass the force and sync options to the kernel. The
kernel supports them, and the force option will be more important

it is forced.

Don't use __dead or __pure in user code. They were obfuscations

of __pure was mostly wrong.

Use the .Fx macro where appropriate.

Get rid of the last vestiges of the old MOUNT_* constants in the
mount_* programs. While we're at it, collapse the four now-identical
mount programs for devfs, fdesc, kernfs, and procfs into links to
a new mount_std(8) which can mount any really generic filesystem
such as these when called with the appropriate argv[0].

Also, convert the mount programs to use sysexits.h.

Hacked up a small man page for mount_ext2fs. The existing man page was
simply a copy of the mount_lfs man page.
