[svn-r5420] Purpose:
Code cleanup/Performance enhancement
Description:
The code to extend the file size in H5FD_mpio_flush is getting run even when
the file size doesn't change. Also, it's sort of sidestepping MPI-I/O when
extending the file, instead of using MPI-I/O features to set the file's size
Solution:
Only extend the file's size when the allocated size has increased. Also
use MPI_File_set_size() to change the file's size. (Including barrier).
Platforms tested:
IRIX64 6.5 (modi4)
