Bug fix
Description:
Fix szip FORTRAN tests..
Solution:
Increase the chunk size to be bigger than the szip 'pixels per block'.
Also add in code that checks for a maximum number of errors and doesn't keep
reporting that thousands of errors have occurred.
Platforms tested:
Linux 2.4 (verbena) w/szip & FORTRAN
Not tested w/h5committest since this combination isn't covered by it.
