Fix possible file corruption when using "new" format object headers and the
size of chunk #0 for an object header transitions between needing 1->2->4->8-
byte encoding for the size and there are "clean" messages in the object header
already. (Usually triggered by flushing the file while adding attributes to
an object)
Tested on:
Mac OS X/32 10.4.9 (amazon)
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Fix error which attempted to allocate space for attribute that has a
'null' dataspace.

Mac OS X/32 10.4.9 (amazon)
FreeBSD/32 6.2 (duty)

Optimize a special case when the source members are a subset of
destination, and the order is the same, and no conversion is needed.
For example:
struct source { struct destination {
TYPE1 A; --> TYPE1 A;
TYPE2 B; --> TYPE2 B;
TYPE3 C; --> TYPE3 C;
}; TYPE4 D;
TYPE5 E;
};
The optimization is simply moving data to the appropriate
places in the buffer. This optimization work is for the Chicago company.
Tested on sol, copper, smirom, liberty.
Added a header message showing the purpose and explanation that the test is
for inoformation and always exits 0.
Also added a summary at the end.
Some other cosmetic changes (moved couple function code up, added some more
printf, fflush statements.)
Tested platform:
kagiso.
Clean up ISOHM code further and get rid of several non-optimal ways
of working with object headers.
Tested on:
FreeBSD/32 6.2 (duty)
Mac OS X/32 10.4.9 (amazon)
Modified the current h5dump test script to use h5import/h5diff calls to validate the binary output. At this moment it can only be used with the native test, since h5import does not deal with input endianess.
tested: linux, sunos 5.10
change _int64 to __int64 within windows macro.
Windows can tolerant _int64 but mingw cannot. So we need to use __int64 to make HDF work on Mingw.
Compiled at linux and Mingw.
h5repack and h5diff hyperslab I/O
changed the limit on which hyperslab I/O is done from 1GB to 128MB
h5repack currently tests this feature by defining a dataset with dimensions of 128MB + 1byte (the datum being 1 byte integer), in which a 1Kb hyperslab was written.
tested: linux
there were some errors in running the tests, but these were in the library, due to a recent check-in that will be fixed shortly (at least we hope :-) )
Check in "unique, but sharable" optimization to ISOHM code, which
allows object header messages that are only used in one object to remain in
the sole user's header, but migrates messages that are used in more than one
header into the ISOHM heap.

Mac OS X/32 10.4.9 (amazon)

Fix H5O_msg_iterate() and H5O_link() to protect cache entries with
better permissions.
Tested on:
Mac OS X/32 10.4.9 (amazon)
FreeBSD/32 6.2 (duty)

Take further advantage of the readers/writer locking in the metadata cache
and push the locking of the local heap up to the routines which call B-tree
routines, which should drastically lower the number of metadata cache protect/
unprotect calls.
Tested on:
Mac OS X/32 10.4.9 (amazon)
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Initial changes to take advantage of readers/writer locking on metadata
cache entries. Reduce the # of protect/unprotect pairs during B-tree iteration
by holding reader lock on B-tree and symbol table nodes while iteration occurs.
This also has the benefit of preventing an iteration callback from
modifying the B-tree being iterated over (which would probably confuse the
B-tree iteration code terribly)
Tested on:
Mac OS X/32 10.4.9 (amazon)
Linux/32 2.6 (chicago)

Don't delete chunks from the dataset's B-tree while we are iterating over
the B-tree, when reducing the size of the dataset's dataspace with
H5Dset_extent().

QSC's mpi implementation does not do collection I/O correctly.
Need to turn some collective support off.
