[svn-r17147] Description:

	Bring r17146 from trunk to 1.8 branch:

        Bring a bunch of misc. improvements & tweaks from the revise_chunks
branch back to the trunk, so that future merges won't be so painful.

Tested on:
	FreeBSd/32 6.3 (duty)
	(h5committested on trunk)

 /* Programmer: 	Robb Matzke <matzke@llnl.gov>
  *	       	Wednesday, October  8, 1997
  *
- * Purpose:	v1 B-tree indexed (chunked) I/O functions.  The logical
- *		multi-dimensional data space is regularly partitioned into
- *		same-sized "chunks", the first of which is aligned with the
- *		logical origin.  The chunks are given a multi-dimensional
- *		index which is used as a lookup key in a B-tree that maps
- *		chunk index to disk address.  Each chunk can be compressed
- *		independently and the chunks may move around in the file as
- *		their storage requirements change.
- *
- * Cache:	Disk I/O is performed in units of chunks and H5MF_alloc()
- *		contains code to optionally align chunks on disk block
- *		boundaries for performance.
- *
- *		The chunk cache is an extendible hash indexed by a function
- *		of storage B-tree address and chunk N-dimensional offset
- *		within the dataset.  Collisions are not resolved -- one of
- *		the two chunks competing for the hash slot must be preempted
- *		from the cache.  All entries in the hash also participate in
- *		a doubly-linked list and entries are penalized by moving them
- *		toward the front of the list.  When a new chunk is about to
- *		be added to the cache the heap is pruned by preempting
- *		entries near the front of the list to make room for the new
- *		entry which is added to the end of the list.
+ * Purpose:	v1 B-tree indexed (chunked) I/O functions.  The chunks are
+ *              given a multi-dimensional index which is used as a lookup key
+ *              in a B-tree that maps chunk index to disk address.
