[svn-r5138] Purpose:
Bug Fix & Code Cleanup Description: The MPI-IO optimized transfer routines (H5S_mpio_spaces_read/H5S_mpio_space_write) are not being invoked in all the cases where they could be used. Additionally, the code for determining if an optimized transfer is wrapped into the actual I/O transfer routine in a very confusing way. Solution: Re-enabled MPI-IO optimized transfer routines in all the cases where they should work. Extracted all the pre-conditions for optimized transfers into separate routines from the transfer routines. Platforms tested: FreeBSD 4.5 (sleipnir) & IRIX64 6.5 (modi4)

New Features
============
+ * Improved performance of "regular" hyperslab I/O when using MPI-IO and the
+ datatype conversion is unneccessary. QAK - 2002/04/02
* Improved performance of single hyperslab I/O when datatype conversion is
unneccessary. QAK - 2002/04/02
* Added new "H5Sget_select_type" API function to determine which type of
