Testing
-------
- Fixed a testing failure in testphdf5 on Cray machines

On some Cray machines, what appears to be a bug in Cray MPICH was causing
calls to H5Fis_accessible to create a 0-byte file with strange Unix
permissions. This was causing an H5Fdelete file deletion test in the
testphdf5 program to fail due to a just-deleted HDF5 file appearing to
still be accessible on the file system. The issue in Cray MPICH has been
worked around for the time being by resetting the MPI_Info object on the
File Access Property List used to MPI_INFO_NULL before passing it to the
H5Fis_accessible call.

- A bug was fixed in the HDF5 API test random datatype generation code
