if there's VL type of data in the dataset, the address of the data is copied
multiple times into the buffer, causing some trouble when the data is released.
Instead, this checkin makes multiple copies of fill value first, then
does conversion on each element so that each of them has a copy of the
VL data. A test is added, too.
Tested it on kagiso, sol, and copper.
Switch the default setting for configure from --enable-production/--disable-debug
to --disable-production/--enable-debug.
Platform Tested:
In kagiso with fortran and C++. No commit test because changes
happened in configure and it is straight forward.
Added H5Lexists() API routine, which determines if a link of a particular
name exists in a group.

Add some sanity checking to improve the resilience of the object header
decoding in the face of a bad reference, or a corrupted file.

Roll changes to SOHM v2 B-tree records into format, to get the format
for them stable while I'm working on debugging the actual support for the
"unique, but sharable" feature.

Eliminate storing # of links in "link info" message, regenerate it
when the object is opened instead.

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)
Fix mis-calculation of chunk #0 size encoding and also catch a few more
places which adjust the size of chunk and have them adjust the encode flags
also. Add some assertions to object header sanity checking routine.
Tested on:
FreeBSD/32 6.2 (duty)
Move "creation order tracked" flag from "group info" to "link info"
object header message and make the "max. creation order value" optional in the
"link info", if the creation order for links is not tracked.
Also, get rid of unused "index names" flag - names are always indexed
currently.
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.

FreeBSD/32 6.2 (duty)
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.

The static szip libraries are working as intended, but when shared szip
libraries are present and intended for use they cannot be opened. A check
has been implemented to test if shared szip libraries are functional on
current platform. If they are not, and the user is trying to use them,
szip is now disbaled and the user is informed.
This issue occurs on kagiso, and the resolution was tested on kagiso.
Minor code rearrangements and comment cleanups, in preparation for moving
attribute tracking information out of object header prefix.

H5O_fill_convert, the background buffer was allocated without clearing. Later in H5T_vlen_disk_write
, library thought there's data in this background buffer. Changed the allocating function to
CALLOC.
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.

Revise latest form of superblock format pretty drastically, to
eliminate unused fields and move rarely used fields into superblock extension.
Finished removing last vestiges of references to (never used) i"shared"
object header message ID.
