Finish deprecating last H5G symbol (H5G_obj_t) - yay!
Lots of misc. library fixes to remove confusion between links and
objects. The tools could still use another pass, to remove h5trav_type_t type
and make the correct distinction between links & objects.

New feature.
Description:
Added routines to report on the amount of storage for:
1) 1.6 btree and heap storage info for groups
2) 1.8 btree, fractal heap storage info for groups, attributes and SOHM table
3) btree storage for chunked datasets
4) 1.8 superblock extension size.
Platform tested:
h5committested.
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
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)
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.

Eliminate storing # of links in "link info" message, regenerate it
when the object is opened instead.
Tested on:
FreeBSD/32 6.2 (duty)
Mac OS X/32 10.4.8 (amazon)
Move ref. count of # of links to an object out of the object header's
prefix and make it a header message instead (since it's a "rare" occurence),
eliminating some more space for each object in the file.
Inserting this "ref. count" message exposed a flaw in the library's
mechanism for locating a message to promote to another chunk and replace
with a continuation message, which required some additional work to fix.
It's still not completely robust, but it's working for more cases now and
detects failures robustly.
Reduced the minimum size of an object header chunk to just enough to
contain a header message prefix and continuation message.
Tested on:
FreeBSD/32 6.2 (duty)
Eliminate message count from new version of object header prefix -
it can be computed when the header is loaded and the table of messages is
built.
Tested on:

Move attribute tracking information out of object header prefix and
make it into a message that is inserted only when attributes are present on
the object.
Tested on:
FreeBSD/32 6.2 (duty)
The main purpose of this checkin was to eliminate the
space used for tracking creation time indices when there is no way they
can be used (i.e. attributes can't be shared in the file and the user hasn't
turned on attribute creation tracking), however there were some other minor
changes which crept in:
- Fix a cache locking deadlock when a shared attribute and one of its
components end up in the same fractal heap direct block.
(This is fixed the "slow" way for right now, until John has time
to add support for readers/writer locking to the cache.
- Optimize attribute copying when a copy will be kept during a v2 B-tree
search.
- When freeing a block on disk, attempt to merge it with the metadata
and "small data" aggregators.
Tested on:
Mac OS X/32 10.4.8 (amazon)
FreeBSD/32 6.2 (duty)
Add object creation property (H5P[s|g]et_obj_track_times) to disable
storing timestamps on objects, which makes the object's header size smaller.
Also, added object header status flags to H5O_info_t struct (for
H5Oget_info/H5Oget_info_by_idx) and cleaned up other field names in the
struct as well.

WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
This initiates the "unstable" phase of the 1.7.x branch, leading up

with it - the format will change again before the release and you will not
be able to read your old files!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
New feature
Description:
Add in baseline "object copy" code from Peter [in the form of a new API

on mounted files yet, but the core functionality is there and working
correctly.

- Clean up guts of object header routines (H5O_*) to allow for some of
the fancieroperations that need to be performed on groups, along with

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.

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.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Code cleanup
Description:
Change some variables that are keywords in C++ to non-keywords.
Platforms tested:
FreeBSD 4.8 (sleipnir)
too minor to require full h5committest
New feature
Description:
Track changes in the internal metadata API with clearing the metadata
dirty flag without flushing object.
Added ability to delete an object header in the file and restore all the
space referenced by various header messages.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/C++
Linux 2.4 (burrwhite) w/FORTRAN
Solaris 2.7 (arabica) w/FORTRAN
IRIX64 6.5 (modi4) w/parallel & FORTRAN
(h5committest not run due to my ongoing difficulties with C++ on burrwhite).
Cleanup
Description:
The H5O_FPHDF5 object was left in this header file by mistake when
the H5Ofphdf5 module was removed
Solution:
Removed it.
Platforms tested:
Linux
Code cleanup
Description:
Clean up miscellaneous warnings which have crept into the code.
Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD.
Adjust gcc compiler flags to be more concise for production mode.
Refactor the H5O code so that there is a stronger boundary between code
in the H5O package and code in the library which just calls H5O routines.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2
Misc. update:
Update MANIFEST if you add or remove any file.
