[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.
