Bring r17429 from trunk to 1.8 branch:
Remove unnecessary v2 B-tree 'retrieve' callback from v2 B-tree clients.

Description:
When an attribute was created with a datatype or dataspace that was shared in
the same object header that the attribute was in, the attribute could not be
deleted. Changes made to ensure that the attribute can be deleted both when the
attribute is in the object header and when it is shared in the heap. Object
header message decode routines now take an "open_oh" parameter to enable them to
avoid opening the same object header twice.
Tested: jam, smirom (h5committest)

one of the handles,
the file didn't have the data. It happened because each handle had its own
object structure, and the empty one overwrote the data with fill value. This is
fixed by making some attribute information like the data be shared in the
attribute structure.
Tested on smirom, kagiso, and linew.

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.

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 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.

Add "set_crt_index" and "get_crt_index" methods for the object header

"object header" fractal heap definitions.

Add H5SM_type_shared() internal routine to determine if a particular
type of header message is sharable in a file.
Correct off-by-one error in computing B-tree record size for densely
stored attributes' name index.
Further progress toward supporting shared attributes in dense storage.

Add first pass of "dense" attribute storage to objects. Lots of parts of
this are stubbed out, but all the tests are passing and I'll work on the corner
cases soon.
Eliminated several unused parameters from object header message callback
routines.
Other, miscellaneous code cleanups, etc. (and probably some things I've
forgotten about... :-)

FreeBSD/32 4.11 (sleipnir)
