Reduce the number of errors under WARNS=6

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.

Take sizeof() the right string for fspath's iovec. The old string was the
same size so this doesn't fix a bug, but it makes it cleaner.

s/filesystem/file system/g as discussed on -developers

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.

Fix the fallback to mount(2) with RELENG_4 kernels and -CURRENT
utilities by catching SIGSYS.

Swap the order of mount and nmount calls. We now call nmount
first, since all the consumers of mount_std in the tree have
been converted to nmount.

Add code to try the nmount(2) syscall when mount(2) failed with
EOPNOTSUPP. This will make things less painful when I will commit
the conversion of devfs, fdescfs and pseudofs to nmount.

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

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.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Don't use __dead or __pure in user code. They were obfuscations
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

Accept mount(8)'s calling convention of passing just the filesystem type
as argv[0].

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.
