FileSystemUtils freeSpaceUnix does not work for HP-UX 11
--------------------------------------------------------

                 Key: IO-109
                 URL: https://issues.apache.org/jira/browse/IO-109
             Project: Commons IO
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 1.2
         Environment: uname -a
HP-UX mbfwdv B.11.11 U 9000/800 3509210950 unlimited-user license

            Reporter: Christopher Olsen


The freeSpaceUnix method does not work under HP-UX.  The df command under HP-UX is the old
System V varient and the fields are not in the correct order.   This diff modifies the code
to use the 'bdf' command when HP-UX is detected:
