faac60c8fc - Add new 'a' switch and runtime option that allows 'top' to display process 
titles extracted from argv vector instead of the real executable names.
  This is useful when you want to watch applications that set their status
  information via setproctitle(3).

bbf750fbff Merge the CPU and WCPU columns in a single %6.2f column, add a new 'C' 
command that toggles between the two and update the ORDER_PCTCPU()
macro to sort correctly by the visible "cpu" value.

This saves 6 more columns in 80-column terminals, making things a lot
better for the COMMAND column.

Tested on:	i386, sparc64 (panther), amd64 (sledge)

32efd26355 - Add a THR column to the process listing, that shows the number of 
threads a process has.  The THR column is disabled and disappears
  when 'H' is hit, because then every thread gets its own output line.
- Allow sorting processes by "threads".

5d320d4b95 This patch merges the sort fields for both pages, so you can (for 
example) view io stats while sorting by process size.  Also adds
voluntary and involuntary context-switch stats to the io page because
there was lots of room.

db6bb7fc01 New feature, provide a display that shows the amount of IO processes 
are doing.  Toggle this mode by hitting "m" or passing the command line
option "-m io" to top(1).  This allows one to identify disk bandwidth
hogs much easier.

e27d79bb28 Changes to allow top to decide whether or not to show multiple threads per 
process. Option -H enables it and it is toggled at the interactive
screen by 'H'.

aee34003d7 This is the long-awaited import of top into the base system (actually, 
the src/contrib/top part right now).  This tools is simply too system-
dependant to maintain it in the ports collection.
