New APIs to add for collective chunk IO
Description:
Three new APIs
H5Pset_dxpl_mpio_chunk_opt_ratio
H5Pset_dxpl_mpio_chunk_opt_num
H5Pset_dxpl_mpio_chunk_opt
for optional optimization choices from users.
Solution:
Haven't added tests yet, won't affect other parts of the library.
Will add tests after urgent investigations of memory leaking problems from NASA Aura team.
Platforms tested:
heping: both parallel and sequential
shanti
Misc. update:

Code cleanup
Description:
Add destructor to match constructor fr VFLs when they are shut down by the
library.
Solution:
Added H5FD_*_term() routines to "undo" changes made in H5FD_*_init()
routines.
Platforms tested:
IBM p690 (copper)
too minor to require h5committest

Bug fix
Description:
Address the failure in the FORTRAN builds by making some more of the
MPI-related typedefs in the library available outside of parallel builds.
Platforms tested:
Linux 2.4 (verbena) w/FORTRAN & C++

Bug fix/optimization
Description:
Address slowdown in MPI-I/O file metadata operations that was introduced
mid-stream. We now _require_ a POSIX compliant parallel file system for the
MPI-I/O file driver (as well as for the MPI-POSIX file driver).
Also optimized file open operation when the file is being created by
reducing the number of collective & syncronizing calls.
Additionally, refactor the MPI routines into a common place, eliminating
duplicated code.
Platforms tested:
FreeBSD 4.9 (sleipnir) w/parallel
h5committest
