f0cc075c4f 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
is threatening to consume all of your disk space.

d1588599c0 Report the next directory being scanned when a ^T is pressed (or any
SIGINFO).  Provides some progress report for the impatient.  This
won't report that we're blocking in our walk due to disk/network
problems, however.  There's no really good way to report that
condition that I'm aware of...

fd543f2759 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.

fe5628d3c1 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.

2966d28c32 Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

ba174a5e38 Back out all POSIXified *env() changes.
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

231a973125 Speed up hardlink detection by using a self-sizing hash
table rather than the old linear list search.

On my "hardlink detection torture test", this reduced
user time from 4700 seconds down to 4.2 seconds
and wallclock time from 1:24:48 down to 1:08.
(Yes, that's over one THOUSAND times reduction in user time. ;-)
In the worst case, the new code doubles peak memory usage,
though it could actually reduce memory usage in many cases.

   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
   arguments to the -d option are not allowed.
