[svn-r18571] Description:

	Bring r18542 from metadata journaling "merging" branch to trunk:

	Bring new object header pin/unpin & protect/unprotect routines and
split-out object header chunk proxy changes from metadata_journaling branch to
"merging" branch, along with some other minor tweaks to clean up compiler
warnings, etc.

	Also: clean up chunk protect/unprotect calls when allocating or freeing
space in a chunk, optimize metadata accumulator code to avoid some re-reading
of information from the file, refactor H5O_pin/H5O_unpin from way they are done
on the merging branch back to way they were previously done on trunk, other
minor code cleanups, etc.
