[svn-r9519] Purpose:

Adding codes for the general MPI derived datatype in order to
better incorporate new fixes of HDF5 library.

Description:
Note: These codes have not been tested for general use.
Don't call these functions in your developments of the HDF5 library.
Also these codes are stand-alone codes, they should not affect
other library codes.

Solution:

Platforms tested:
Heping(C and Parallel linux 2.4, mpich 1.2.6)
Arabica(C,C++,Fortran, Solaris 2.7)
Copper(C,c++,Fortran, AIX 5.1, NOTE: c++ FAILED, seems not due to the recent check-in)

Misc. update:
