Description:
Added line #'s to a bunch of the error printf's, so it's easier to locate
where an error occurs.

Bug fix
Description:
The tests recently added for checking a file's freespace and verifying the
new fields added to the H5G_stat_t structure use H5T_NATIVE_INT as the type for
the datasets and attributes they create. Because the tests check explicit file
sizes, this causes problems on Crays, where a native int is 64-bit instead of
32-bit.
Solution:
Change the tests to use H5T_STD_U32LE instead of H5T_NATIVE_INT.

Bug fix
Description:
The VL type conversion routine attempt to align it's destination buffer to
an offer that will work for both hvl_t and char * types, but the algorithm used
fails to work correctly on Cray machines.
Solution:
Give up on attempting to align the buffer when it's allocated on the stack.
Just dynamically allocate it instead.

Code Improvement
Description:
Changed from passing a structure into a function by value into
passing it in by pointer. Noticed this while compiling with a highly
optimizing compiler which took >30 minutes to analyze the program
(granted, this is the compiler's fault, but in general, it's better
to pass large structures in by pointer and not by value).
Platforms tested:
Linux (specific to h5import, so only needed to test on one platform)
Misc. update:
Bug fix
Description:
When too many messages were inserted into an object header, the library
had an internal pointer to the "new message" that was pointing to the incorrect
location when the array of messages was re-allocated.
In the worst case, this could cause a file to be corrupted.
Solution:
Update the internal pointer when the array is re-allocated.

Add feature
Description:
Add H5Fget_freespace() routine, to check the amount of free space in a
file. This information is only valid until the file is closed currently,
however (until we start recording the free space information in the file
itself).

Improved algorithm (bug fix, sorta)
Description:
The internal algorithm for adding new IDs in the ID manager code (H5I) was
adding new IDs to the front of the linked list and never adjusting the order
of the items on the list (unless an ID was deleted). If many new objects were
created, they would push earlier ones _way_ down the list (especially if the
objects were being leaked in the application, as they appear to be in the
current HDF-EOS5 library) and would cause O(n) search time for items on the
list.
The ID caching code in the ID manager was avoiding this behavior sometimes,
but it was adding IDs that were looked up to the very tail of the cache and
they would frequently leave the cache before helping.
Solution:
Implemented a "move to front" scheme for the linked list of IDs, which
improves the lookup situation for frequently accessed objects.
Removed ID caching code now, as the "move to front" algorithm actually
works better.

Description:
Re-worked ohdr test to use modification time messages instead of symbol
table messages, now that the library correctly tries deleting the
local heap and B-trees for the symbol tables (which didn't exist and

reference counts are being tracked correctly, etc.

Bug fixes and code cleanup
Description:
Lots of changes here:
- Fixed bug #691 - when shared datatypes are used in attributes they
are incorrectly copied into the attribute instead of referring
the the named datatype in the file. This required bumping the
version of the attribute message. The new version of the attribute
message is only written out when a shared datatype is used in
the attribute. [Also, this format change made the size of the
attribute smaller.]
- Added information to attribute debugging routine so that shared
datatypes are displayed correctly with the h5debug tool.
- Refactored the H5O* routines to extract code that was common to
several routines into subroutines to call.
- Added 'link' method for H5O message sub-classes, which increments
the link count on shared objects when a message is created which
shares them.
- Corrected [unreported] bug where the link count was not being
decremented on the shared object when a object header message
with a reference to that object was deleted from the file.
- Reduced size of shared message from 49 bytes (which was incorrect
anyway and should have been 48 bytes) to 10 bytes, which required
bumping the version of "shared" messages.
- Refactored some of the shared datatype routines to allow for easier
queries of "committedness" internally to the library and also
added routine to easily increment/decrement the reference count of
a shared datatype.

Bug Fix
Description:
The FPHDF5 code couldn't create a dataset then access it. Turns out
that the "O_find_in_ohdr" code was protecting the object header which
pulls it into the cache then unprotecting it. However, this caused
the cache entry to be blown away and THEN we'd try to reread the
entry (via AC_protect) but it didn't have all of the data that the
find_in_ohdr function decodes for us decoded. It was also kind of
unnecessary since we can just protect then call O_find_in_ohdr.
Solution:
Removed the AC_protect and AC_unprotect from O_find_in_ohdr. Called
AC_protect before calling the O_find_in_ohdr function.
