Args: path - Path name of file or directory on file system of concern
over - pointer to flag that is set if the user is over quota
Returns: If *over = 0, the number of bytes free in disk quota as per
the soft limit.
If *over = 1, the number of bytes *over* quota.
-1 is returned on an error looking up quota
0 is returned if there is no quota
BUG: If there's more than 2.1Gb free this function will break
