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.

Minor code rearrangements and comment cleanups, in preparation for moving
attribute tracking information out of object header prefix.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
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.

Make H5O_protect/H5O_unprotect use pinned cache entries instead of
protected entries (allowing the object header routines to be semi-reentrant).
Tested on:
FreeBSD 6.2 (duty)
Allow "big" attributes to push attribute storage into "dense" form
immediately, to accomodate storing the attribute. (This is only allowed
in the "latest" version of the format).

Tested platform:
Kagiso only since it is only a comment block change. If it works in one
machine, it should work in all, I hope. Still need to check the parallel
build on copper.

working for "compact" attribute storage.

Fixed a bug in reference counting messages that are referenced by shared

Tested on mir, smirom, and Windows.
Add more tests for checking that writing to shared attributes works
