algorithm to (optionally) avoid sharing selection data structures.
Tested internal code (including with valgrind) by setting VDS code to
avoid sharing selection, has since been changed to share selection for
performance, so this code is not yet tested in regression tests. API
has not been tested.

Add checks to CMakeLists.txt for MPI_Mprobe and MPI_Imrecv
Description:
Applied the typo fixes from user's report.
The previous pull request couldn't be merged because it was too old,
and it was too complicated for me to resolve conflicts.
Platform tested:
Linux/64 (jelly) - very minor
* commit '54957d37f5aa73912763dbb6e308555e863c43f4':
Commit copyright header change for src/H5PLpkg.c which was added after running script to make changes.
Add new files in release_docs to MANIFEST. Cimmit changes to Makefile.in(s) and H5PL.c that resulted from running autogen.sh.
Merge pull request #407 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:hdf5_1_10_1 to hdf5_1_10_1
Change copyright headers to replace url referring to file to be removed and replace it with new url for COPYING file.
Complete revamp of package initialization/shutdown mechanism in the library.
Each package now has a single init/term routine.
This new way should avoid packages being re-initialized during library
shutdown and is also be _much_ more proactive about giving feedback for
resource leaks internal to the library.
Introduces a new "module" header file for packages in the library
(e.g src/H5Fmodule.h) which sets up some necessary package configuration macros
for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly
modified version of this header, src/H5FDdrvr_module.h)
Also cleaned up a bunch of resources leaks all across the library and tests,
along with addressing many warnings, as I encountered them.
Tested on:
MacOSX/64 10.10.5 (amazon) w/serial & parallel

Revert r25273, 25283 & 25439 (the hyperslab improvement changes). They
are buggy and it's taking me a long time to correct the problem. I'll check
in a revised form of the changes when I've got them straightened out.
Tested on:
Mac OSX 10.10.0 (amazon) w/gcc 4.9.x, C++, FORTRAN

Bring in Chao/Neil/my changes to optimize hyperslab selection operations
further, along with 3 new public API routines: H5Scombine_hyperslab(),
H5Sselect_select() and H5Scombine_select(), along with many minor cleanups to
the code and fixing a few compiler warnings.
Tested on:

view objects. The addition of view objects in the fastforward project
is expected to be brough into the trunk sometimes in the future, which
is why we need to make this change.
Tested Manually on Jam and Ostrich.
Tested with h5commitest - Koala with intel compilers failed, but nothing had to do with those changes.
error on Koala: error while loading shared libraries: libirng.so
Correct error reported by user (Martin Otte) where we weren't using
realloc'ed buffer in MPI datatype code.
Tested on:

Refactor function name macros and simplify the FUNC_ENTER macros, to clear
away the cruft and prepare for further cleanups.
Tested on:

Bring "shape same" changes from LBL branch to trunk. These changes
allow shapes that are the same, but projected into dataspaces with different
ranks to be detected correctly, and also contains code to project a dataspace
into greater/lesser number of dimensions, so the I/O can proceed in a faster
way.
These changes also contain several bug fixes and _lots_ of code
cleanups to the MPI datatype creation code.
Many other misc. code cleanup are included as well...

No need for h5committest, just whitespace changes...
Omnibus raw data I/O revisions, with wide-ranging changes and
refactoring, in order to prepare for implementing "fast append" feature.
These changes remove the majority of the code duplication for raw data
I/O which has crept in over the last ten years and introduces a more object-
oriented design for operating on different types of dataset storage.
Chunked storage no longer has it's own I/O routines, it is now handled
as either contiguous (if chunk is not pulled into the cache) or compact (if the
chunk is cached in memory).
No bug or feature changes, at least intentionally... :-)

Tested platform:
Kagiso only since it is only a comment block change. If it works in one
machine, it should work in all, I hope. Still need to check the parallel
build on copper.
Purpose:
Add some comments and error checking codes for collective chunk IO code.
Description:
Solution:
Platforms tested:
AIX 5.1(copper), too minor to test at other platforms.
Misc. update:
Purpose:
bug fix for collective chunk IO
Description:
When using calloc to allocate an MPI datatype, one should use sizeof(MPI datatype) instead of sizeof(equalivent non-MPI datatype) to assign the value, this causes the problem at 64-bit platforms such IRIX65 and AIX 5.1.
Solution:
Correct it.
Platforms tested:
AIX 5.1 and IRIX6.5(at NCAR).
Misc. update:
Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches
difficult.
Solution:
Ran this script in each directory:
foreach f (*.[ch] *.cpp)
sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Code cleanup
Description:
Refactor, simplify and cleanup Kent's recent checking for collective
chunk I/O. There's a bug that I need to talk to Kent about and some more
cleanups still, but this is reasonable for an interim point.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor for h5committest
bug fix for collective chunk IO, phase 1
Optimization hasn't been done yet, the collective chunk IO bug should be fixed.
Description:
In chunking storage, memory space and file space will be remapped, So to check
whether file space and memory space are regular in order to use optimized MPI derived
datatype for collective call one has to check per-chunk wise instead of per hyperslab wise.
Even a regular memory space will be stored in span-tree and will be irregular before chunk IO.
Solution:
1. Check file space and memory space per chunk wise instead of per hyperslab wise.
2. For collective IO mode, number of chunks covered by hyperslab may be different. Since we are
handing per chunk per IO, for the extra chunk IO for some(not all) processors, collective mode will
cause program hanged. So for the extra chunk Io mode independent IO has to be used.
3. On some platforms, Complex MPI derived datatype is not working, so we have to use independent IO for collective IO mode if the selection is irregular. However, when the selection is regular, we do want to use collective IO since that will improve performance. Special cares have to be added for this case.
Platforms tested:
copper(AIX 5.1) Linux(heping mpich 1.2.6), Teragrid machine, Cobalt(altix), modi4
Misc. update:
Activating collective IO supports for irregular selction inside HDF5 dataset.
This support doesn't include to build the final complicated MPI derived datatype support for chunking storage.
Description:
Support collective chunk IO for both contiguous and chunking storage for irregular selection( using H5S_SELECT_OR for multiple hyperslab selection)
Solution:
Using MPI derived datatype to realize this feature.
Problems still need to be investigated:
Big size irregular hyperslab selection test may cause MPI hang or abnormalexit with MPICH family on various platforms. This is really hard to debug since sometimes it can work and sometimes it cannot work. We will continue investigating those cases. This may not be parallel HDF5 bugs since with the recent version of poe at IBM platforms, all tests passed.
Platforms tested:
1. Linux heping 2.4.21-27.0.1 with mpich
2. AIX 5.1 copper with mpcc_r
3. Altix cobalt SGI linux 2.4.21-sgi304rp05031014_10149 with icc -lmpi
4. Linux Cluster SDSC TG, intel 8-r2 with mpich 1.2.5
5. NCSA Linux Cluster Tungsten, MPICH-TCP-1.2.5.2, Intel 8.0 under lustre
6. NCSA Linux Cluster Tungsten, MPICH-LAM-INTEL711, sometimes not working
7. NCSA Linux CLuster Tungsten, champion-pro-1.2.0-3, not working for other collective IO tests, but work for irregular selection collective IO test.
