minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

The mntopts(3) functions support operations associated with a mount
point. The main purpose of this commit is to document the mntopts(3)
functions that now appear in 18 utilities in the base system. See
mntopts(3) for the documentation details.
The getmntopts() function appeared in 4.4BSD. The build_iovec(),
build_iovec_argf(), free_iovec(), checkpath(), and rmslashes()
functions were added with nmount(8) in FreeBSD 5.0. The getmntpoint()
and chkdoreload() functions are being added in this commit.
These functions should be in a library but for historic reasons are
in a file in the sources for the mount(8) program. Thus, to access
them the following lines need to be added to the Makefile of the
program wanting to use them:
SRCS+= getmntopts.c
MOUNT= ${SRCTOP}/sbin/mount
CFLAGS+= -I${MOUNT}
.PATH: ${MOUNT}
Once these changes have been MFC'ed to 13 they may be made into
a library.

| Re-implement the root mount logic using a recursive approach, whereby each
|root file system (starting with devfs and a synthesized configuration) can
|contain directives for mounting another file system as root.
|------------------------------------------------------------------------
This commit adds a mount.conf(8) man page which documents
the root mount logic. mount.conf(8) also provides some examples
for the /.mount.conf file, which can be used to change the root mount behavior.

- Teach the mount program to call the nmount() syscall directly
- Preserve existing method of calling mount() for UFS, until we clean things
up.
- Preserve existing method of forking and calling external mount programs for
mfs, msdosfs, nfs, nfs4, ntfs, nwfs, nullfs, portalfs, reiserfs, smbfs,
udf, umapfs, unionfs
- devfs, linprocfs, procfs, ext2fs call nmount() syscall directly, since
that is all those external mount programs were doing

libufs, which only works for Charlie root.
This change reverts the introduction of libufs and moves the
check into the kernel. Since the f_fstypename is the same
for both ufs and ufs2, we check fs_magic for presence of
ufs2 and copy "ufs2" explicitly instead.

getvfsent() in most cases. (The main exception is when /etc/fstab
still hasn't been converted to use a slice for the root device, the
root device is a SCSI device, and the /dev/sd* inode for this device
still hasn't been renamed to /dev/da*.)
something that might refer to the compatability slice rather than the
correct slice entry, try all the possible slice entries first.
This is a compatability hack to deal with the case where the kernel has
correctly mounted the root filesystem out of its slice, but the user
has not updated their /etc/fstab file to reflect this. A diagnostic
is emitted if the mount succeeds, indicating that the file should be
updated.
This is a prelude to fixing the kernel to behave as alluded to above.

- 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!
