du: Allow multiple -HLP options, the last one wins.

This matches 4.4BSD tradition and other utilities with these options and is
required by POSIX (POSIX does not specify -P, only -HL).

Update du(1):

- Sort arguments alphabetically where appropriate
- '-B blocksize' is not mutually exclusive of '-h|-k|-m'
- Mention '-t' in synopsis
- Other wording improvements
- Update usage() output to reflect the new synopsis [1]
- Other miscellaneous improvements

Add a -t switch for masking output that's above or below certain thresholds.
This switch makes it a lot easier to locate problem areas when a process

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.

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.

* add a -c option which displays the grand total of all files
counted.

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

* 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.

* change the behaviour of argument processing so that negative
