Renumber cluase 4 to 3, per what everybody else did when BSD granted

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add two new options to du(1):
-A Display the apparent size instead of the disk usage. This can be
helpful when operating on compressed volumes or sparse files.

-B blocksize
Calculate block counts in blocksize byte blocks. This is differ-
ent from the -k, -m options or setting BLOCKSIZE and gives an
estimate of how much space the examined file hierachy would
require on a filesystem with the given blocksize. Unless in -A
mode, blocksize is rounded up to the next multiple of 512.

The former is similar to GNU's du(1) --apparent-size. The latter is
different from what GNU's du(1) -B does, which is equivalent to setting
BLOCKSIZE in our implementation and is rather pointless as it doesn't add
any real value (i.e. you can achieve the same with a simple awk-script).

No change in the normal output or processing.

- Import the HEAD csup code which is the basis for the cvsmode work.

Implement from scratch a -l option for du(1), to match the same option
of the GNU utility. The default behavior of our original `du' is to
count hardlinked files only once for each invocation of the utility.
With the new -l option they count towards the final size every time
they are found.

* re-word parts of the man page which I felt were badly worded

* change the behaviour of argument processing so that when more
than one of the -P, -H and -L options are specified it will
print an error message, rather than choosing the last option
specified, this behaviour is more logical and consistent with
other utilities.
