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.
