841fe8e83f Convert fsbtoblk() from a macro to a function. The redundant
instances of 64-bit arithmetic were costing 775 bytes, and the
inlining offered no benefit.  Moreover, ambiguity as to the argument
types led to the introduction of a bug (see rev 1.56).

Also, remove some casts that are now clearly redundant.

ae21f5ad2c And a bandaid so that the output of "available space" is correct when
using -m and -g switches and "available space" is negative (i.e. when
the file system is already using the root-reserved minimum free space).

16fc3635f7 Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

fde81c7d8e Update the statfs structure with 64-bit fields to allow
accurate reporting of multi-terabyte filesystem sizes.

You should build and boot a new kernel BEFORE doing a `make world'
as the new kernel will know about binaries using the old statfs
structure, but an old kernel will not know about the new system
calls that support the new statfs structure. Running an old kernel
after a `make world' will cause programs such as `df' that do a
statfs system call to fail with a bad system call.

0e7d023f34 Fixed exit code in previous commit. "var++" to set a flag to nonzero
is a style bug at best.  When the variable isn't a flag, it potentially
overflows after a large number of settings.  Here the number of settings
is limited by ARG_MAX, but the variable is the exit code so it became
bogus after the second setting and effectively overflowed to 0 after
approx. 128 settings.

Fixed some style bugs involving comments in and near previous commit.

Clarification of previous commit message: df -t didn't give undefined
behaviour, and the behaviour used to conform perfectly with the man
page, since the buggy behaviour is documented in the BUGS section.  -t
just worked when no files or file systems were specified, and was just
ignored if a file or file system was specified.

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.

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.
