Fixes Bug  998930 -  comparison of date DD with date YYYYMMDD needs methods not hard coding

most places in the FS crash storage code base used a method to calculate the base directory name based on date.  Testing in staging over the weekend revealed that not all the places used a method.  The meant that comparisons were not valid and orphans were being left behind when the consuming thread ran into the bucket where the producing threads were working.  

Solution: make sure that there are no hard coded base date directories...
