a461bd1507 Add a new line to top that provides a brief summary of the ZFS ARC memory 
usage on hosts using ZFS.  The new line displays the total amount of RAM
used by the ARC along with the size of MFU, MRU, anonymous (in flight),
headers, and other (miscellaneous) sub-categories.  The line is not
displayed on systems that are not using ZFS.

06bb0a9299 Clarify that the cached file data pages included in the "Wired" count 
in top are the BIO-level cached data (i.e. "Buf"), since the previous
phrase was a bit ambiguous with the "Cache" count.

a73a4dbfbb - Document the -H option and 'H' key alongside other options and keys 
rather than at the bottom of the manpage.
- Remove an obsolete comment about SWAIT being a stale state.  It was
  resurrected for a different purpose in FreeBSD 5 to mark idle ithreads.
- Add a comment documenting that the SLEEP and LOCK states typically
  display the name of the event being waited on with lock names being
  prefixed with an asterisk and sleep event names not having a prefix.

77592f5333 Touch up the sample memory usage numbers a bit, to avoid wrapping 
on terminal boundary.  While here add definition for 'G' and fix
the indentation of 'K' units.

description of the "Inact" memory.  (They count pages in
the cache/inactive page queues, respectively.)

788547d4cf 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'.
