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.

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.

Make H5O_protect/H5O_unprotect use pinned cache entries instead of
protected entries (allowing the object header routines to be semi-reentrant).

Add H5Aget_info_by_idx & H5Aget_name_by_idx routines, along with
refactoring underlying indices code to handle those sort of queries.
Simplify the link callback routines a bit.
Minor other cleanups.

copyright notice.
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 attributes to the message classes that use the shared message
method calling interface, completing the transition. The other mechanism will
be removed shortly.

Add support for renaming compact & dense/shared & non-shared attributes in
all cases.

Add support for opening attributes in dense and/or shared storage by
index.
Move routines for building and operating on tables of attributes into
separate source module.
Fix bug where reverting from "dense" to "compact" storage would 'unshare'
attributes.
Minor code cleanups, etc.
