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
Linux/64 3.10.x (kituo) w/serial & parallel
Linux/64 2.6.x (ostrich) w/serial

Purpose:
Remove H5_MPI_SPECIAL_COLLECTIVE_IO_WORKS and
H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS #defines from source.
Description:
Two advanced parallel functionalities, special collective IO and
complex derived datatypes, are not supported by older
implementations of mpi, and thus our code limits the use of these
features with #ifdefs and has checks in configure to set them (or
not). Unfortunately, configure can't actually run a parallel check
to see if these features are working (nor not) so it resorts to
looking in the config files where they are explicity enabled or
disabled based on versions of mpi, sytems being built on, or for
no documented reason at all (i.e. just set to on or off as some
'default'). Overriding these settings is easy if need be, provided
it is known that it needs to be done to get improved performance,
and oftentimes it is not.
Most new MPI implementations successfully handle the functionality
requested when these #defines are set, and many of the "turn these
features off" cases in the config files are for old (> 5 years)
versions of MPI and retired systems (such as NCSA's tungsten).
Therefore, the decision has been made to remove the support for
these old versions of MPI and systems that cannot handle these
behaviors. The #ifdefs and supporting setup in the config/ files
and configure script has been removed, and the code executed when
these options were not set removed from the source.
In passing, this commit also cleans up some whitespace issues in
both t_mpi.c and H5Dmpio.c. Furthermore, in t_mpi.c, the special
collective IO test was not getting regularly run due to it being
written to work only with four processes (we regularly test with
six, previously with three), and thus it failed when actually run
due to an out of bounds data buffer assignment. It has been
modified to run at any number of processes greater than four, and
the memory problem has been fixed so the test passes.
Tested:
jam, h5committest, ember

when it encountered
error and wanted to exit the test program. This was not good since if only a
subset of processes called MPI_Finalize(), the other processes will likely
hang. That happened in AIX that it would waited till the alarm signal to kill
the processes. Definitely a waste of time.
Solution: Changed it to call MPI_Abort.
That showed another problem. HDF5 has setup atexit post-process to try to close
unclose objects, release resources, etc. But if the MPI processes have
encountered an error and has been aborted, it is not likely any more MPI calls
can function properly. E.g., it would attempt to free some communicators in
the HDF5 MPIO file handle. It would again hang.
Solution: need to call H5dont_atexit() to disable any atexit post-processing.
This must be done early, like before calling H5open. This is added to each
parallel test main program.
testphdf5.h:
Changed macros VRFY and MESG. Added comments too.
testphdf5.c:
t_mpi.c:
t_cache.c:
t_shapesame.c:
Added H5dont_atexit.
Tested: h5committest.

t_file.c: replace the old variable, color, with a more meaningfule name of
is_old.
t_mpi.c: use the official mpi_file_delete, instead of remove, to delete a file
in MPI environment.
Tested:
Only jam in parallel as changes are trivial.

Remove trailing whitespace from C/C++ source files, with the following
script:
foreach f (*.[ch] *.cpp)
sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end
Tested on:
Mac OS X/32 10.5.5 (amazon)
No need for h5committest, just whitespace changes...

doesn't return correct
file size from MPI_File_get_size. Bypass this problem by replacing it with
stat. Add an option --disable-mpi-size in configure to indicate this function
doesn't work properly. Add a test in testpar/t_mpi.c, too. If it returns wrong
file size, print out a warning.
Tested on kagiso (parallel) because already tested the same change to v1.6 on
several platforms (kagiso, cobalt, copper, and sol).

Add new tests
Description:
Collective IO doesn't work for some platforms/mpio packages when more than
one process has no contributions to IO.
Solution:
1. Add a collective IO test to verify the correctness of the library when
more than one process has no contributions to IO.
2. Add the similar MPI-IO test in t_mpi to help us maintain in more platforms.
Platforms tested:
heping, mir, copper

bug fix.
Description:
The complex derived datatype test assumed that the fill value would be 0. This is not
the case on all systems.
Solution:
Modified the test to check against a known value in the outbuf array, instead of the fill value.

A bug fix
Description:
MPI_Status_IGNORE is treated as a NULL pointer for mpich 1.2.4 or similar MPI packages.
It caused segmentation fault for MPI derived datatype test.
Solution:
Define MPI_STATUS status,
and pass &status into MPI_File_read and MPI_File_write.
Platforms tested:
too trivial to test.

Improvement.
Description:
The test may hang if there are system failures that some processors
are not working.
Solution:
Added the ALARM calls to limit all tests be done with the default
alarm time. So, even if a process is hanging, the ALARM signal
would terminate the process.
Platforms tested:
tg-login2 of NCSA.

"bug fix"
Description:
The test_mpio_derived_dtype() often hangs when fails. So it was
not run by default to avoid hanging the daily tests or confusing
users. But then new system or new codes in collective chunk fails
while one can't tell for sure if it is because of the complicated
derived type failures or something else.
Solution:
Changed the logic so it is skipped only if it is known that
the complicated MPI derived type does not work. (This is
indicated by macro H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS NOT
defined.
Platforms tested:
heping pp (where it is tested by default).
Modi4 pp (where it is SKIPPED by default.)
I also forced modi4 to test it and modi4 said it actually
is working and should change the setting of
H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS to working?!!

Code cleaning.
Description:
The block of code that is conditioned by the H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS
and manipulates the return code of test_mpio_derived_dtype, does not really
belong in main. If return code of test_mpio_derived_dtype needs to be
adjusted, it should be done in test_mpio_derived_dtype.
Solution:
Moved that block of code test_mpio_derived_dtype.
Platforms tested:
heping PP.

Provide a way to warn users on the usage of collective IO because of
potential MPI-IO bugs for some platforms.
Also provide a way for users to give us feedback if the vendor has
already fixed the problem so that we can turn off the hard-code macro
in our configure description file.
Description:
See above.
Solution:
Use a simple MPI complicated derived datatype program to check
whether derived data type works for this MPI-IO package.
Print out some messages to warn users if not working as we had expected.

Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN
IRIX64 6.5 (modi4) w/FORTRAN
Linux 2.4 (heping) w/FORTRAN & C++
