5965373e69 - Introduce a new struct xvfsconf, the userland version of struct vfsconf.
- Make getvfsbyname() take a struct xvfsconf *.
- Convert several consumers of getvfsbyname() to use struct xvfsconf.
- Correct the getvfsbyname.3 manpage.
- Create a new vfs.conflist sysctl to dump all the struct xvfsconf in the
  kernel, and rewrite getvfsbyname() to use this instead of the weird
  existing API.
- Convert some {set,get,end}vfsent() consumers to use the new vfs.conflist
  sysctl.
- Convert a vfsload() call in nfsiod.c to kldload() and remove the useless
  vfsisloadable() and endvfsent() calls.
- Add a warning printf() in vfs_sysctl() to tell people they are using
  an old userland.

After these changes, it's possible to modify struct vfsconf without
breaking the binary compatibility.  Please note that these changes don't
break this compatibility either.

When bp will have updated mount_smbfs(8) with the patch I sent him, there
will be no more consumers of the {set,get,end}vfsent(), vfsisloadable()
and vfsload() API, and I will promptly delete it.

85ed93337f Unconditionally update the maximum field width statistics when we
refetch the filesystem information in MNT_WAIT mode. This avoids
incorrect column alignment that sometimes occurs with NFS filesystems.

532aff98f6 Remove the private code for reading UFS superblocks, this does not belong
in df(1) when we have multiple filesystem types, and the complications of
handling UFS2 pushes this over the edge.

Use the .../mount/extern.h to get prototypes of the functions we
borrow from there.  Constify things to match.  (why aren't these
functions in a lib anyway ?)

Make everything static and set WARNS?=5.

The way the "df diskdevice" thing works for unmounted diskdevices
is not very general.

5b42dac8ec Most modern OSs have the ability to flag certain mounts as ones to
be ignored by default by the df(1) program.  This is used mostly to
avoid stat()-ing entries that do not represent "real" disk mount
points (such as those made by an automounter such as amd.)  It is
also useful not to have to stat() these entries because it takes
longer to report them that for other file systems, being that these
mount points are served by a user-level file server and resulting in
several context switches.  Worse, if the automounter is down
unexpectedly, a causal df(1) will hang in an interruptible way.

2ffc1ec6ca The manual page of df called cd9660 file systems by the name
isofs while the df command itself used the name iso9660fs or
        cdfs. Both of these were inconsistent with the name cd9660 which
        is used by the mount command. I modified df to recognize all of
        the names cd9660, cdfs, isofs, and iso9660fs, and take them all
        to refer to the same thing. Naturally I added a note of this
        behaviour in the manual page too.

51ea8b57b8 Partially fixed negative and truncated "Avail" counts in df output.
This fixes PR943.

ffs/ffs_vfsops.c:
ffs_statfs() multiplied by (100 - minfree) as part of calculating the
minfree percentage (complemented in 100%), so with the standard minfree
of 8, it was broken for file systems of size >= 1TB/92 = 11GB.  Use the
standard freespace() macro instead.  This also fixes a rounding bug (the
"Avail" count was sometimes 1 too small).

ffs/* (not fixed):
The freespace() macro multiplies by minfree, so with the standard
minfree of 8, it is broken for file systems of size >= 1TB/8 = 128GB.
This bug is more serious since it affects block allocation.

ffs/ffs_alloc.c (not fixed):
Ordinary users are sometimes allowed to allocate 1 (partial) block
too many so that the "Avail" count goes negative.  E.g., if there is
1 fragment available and the file is fairly large, one more full
block is allocated.

df/df.c:
ufs_df() used/uses essentially the same code as ffs_statfs(), so it
had/has the same bugs.

ufs_df() gratuitously replaced "Avail" counts of < 0 by 0, so it
gave different results for non-mounted file systems in this case.
