[svn-r2057] Purpose:
Bug fix for parallel mode.
Description:
H5FD_mpio_tas_allsame was called for all cases, even when
MPIO is not used for access. That corrupted the internal
file handle structure.
Solution:
Define a macro, IS_H5FD_MPIO(f), for testing if f is opened with
MPIO access. Will call H5FD_mpio_tas_allsame only if this
condition is true.
Platform tested:
O2K, both -64 and -n32 modes.
