Description:
Changed a macro in H5FDwindows.c from IO_BUF_SIZE to a more specific WINDOWS_MAX_BUF, and moved it to our H5pubconf.h, where users can customize it to their own preference.
This value is needed because of a bug in the Windows _write function, it is unsafe to write buffers larger than 2GB-1 bytes in one write.
Tested:
VS2005 on WinXP.
Fix writing variable-length datatype fill values for contiguous dataset
storage

Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Description: When the compiler has the __offsetof__ extension, the
H5_HAVE_OFFSETOF macro will be defined. When the compiler
does not have the extension, the macro will remain undefined.
Tested: kagiso
der /src. So when gmake check-install is run for HDF5 examples, it will fail. Th
e fix is to include a macro #ifdef H5_HAVE_WINDOW around #include H5FDwindows.h
so that H5FDwindows.h will only be included on windows, not on other platforms.
We've fixed with the same way for other source code that includes H5FDwindows.h.
This has been tested with h5committest. However, it takes a few hours to test all tests and except kagiso. Tests on linew and smirom cannot finish. It takes forever for the fheap test.
And for parallel test at kagiso, ph5diff test seems to be hanged. I think all of our changes will only affect windows. So in order not to block other developers to check in their code, we just go ahead to check our changes.

Hook "default VFD" configure macros into library.
Also, make "default VFD" default to sec2 instead of nothing.
Tested on:
FreeBSD/32 6.2 (duty)
FreeBSD/64 6.2 (liberty)
Mac OS X/32 10.4.9 (amazon)
Description: this flag will define the macro H5_DEFAULT_VFD in src/pubconf.h
and set it to be either H5FD_SEC2 or H5FD_STDIO, depending on the
value set with the configuration flag (either sec2 or stdio).
Tested: kagiso, smirom, linew
Fix compact dataset storage to initialize VL datatype fill values
correctly.
Also, fix bug in global heap code when the fix action on a global
heap is to delete an object in a heap with no free space.

Add a little more information to the debugging routine, for VL datatypes.
Minor code cleanups

Too minor to require h5committest
Description: a new configure flag has been created that will now set a macro
in the test/Makefile. The flag is with-default-vfd=. When set to
a virtual file driver (e.g. "--with-default-vfd=sec2"), the macro
DEFAULT_VFD will hold this value.
Tested: kagiso, smirom, linew
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).

Incremental step forward in fixing problems with fill values that have

Fixed a bug at copying shared reg_ref attribute. The ref values of an attribute
was not writen in file. The post_copy_file() at H5Oattr.c only updates the value
in memory.
To fix the problem, we added H5O_shared_post_copy_file(), which delete the attribute
in file (with the incorrect value) and create an new attribute with the correct values.
I added the following functions:
H5Oshared.c:H5O_shared_post_copy_file(H5F_t *f, hid_t dxpl_id, H5O_t *oh, void *mesg);
H5Oshared.h: H5O_SHARED_POST_COPY_FILE
and modified the following files to include shared_post_copy_file()
H5Oattr.c
H5Odtype.c
H5Ofill.c
H5Opline.c
H5Osdspace.c
Change back to clearing memory buffers by default, but give users option
to disable this, for performance reasons (--disable-clear-file-buffers).
Also, add configure option (--enable-using-memchecker) to conveniently
control making the library "play nice" with memory checking tools like valgrind
and purify.

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)

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.
Clean up ISOHM code further and get rid of several non-optimal ways
of working with object headers.

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.

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.

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)
