[svn-r24645] - Add Neil's VL datatype changes from the Netvol to H5VLiod_common.c

- Refactor VL datatype handling for datasets to use Neil's functions. 
  * Still can't handle complicated VLs (nested, compunds, etc...). 
  * Need MPI mercury plugin fix and to update Neil's buffer construction at server for IOD storage.
- Fix and Update IOD storage for VL dataypes in arrays by algorithmically calculating the BLOB ID.
- Add test for Array VL datatypes to the FF test suite.
- Other minor fixes.
