code: make df(1) show space used by historical data on the HAMMER filesystem

completed by: gh0st

mentors: Samuel J. Greear

Determine the best course of action and implement it. Either df will have to calculate the sum of all history entries for a filesystem (possibly very time consuming) or HAMMER will have to be modified to store the amount of historical data.

Add a flag to the df(1) utility and make it show the size of the historical data used by the HAMMER filesystem.

Document this flag in the df(1) manpage.
