Purpose: This a fix for bug #921

Description: On platforms where big test runs, it creates a set of
             "solid" 1GB files. Test will take forever (modi4) or will fail
             if quotas are exceeded.

Solution: Default library behavior is to allocate dataset space earlier and
          to write fill values. I changed the test to use late space allocation
          and never write fill values.

Platforms tested: True64 (PSC), modi4 (sequential and parallel), arabica with 64-bit
                  option(test was skipped there). I also enabled szip and it passed :-)
