[svn-r8823] Purpose:
Code optimization
Description:
Since the raw B-tree nodes are the same size and only used when reading in
or writing out a B-tree node, move raw B-tree node buffer from being per node
to a single node that is shared among all B-tree nodes of a particular tree,
freeing up a lot of space and eliminating lots of memory copies, etc.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
