[svn-r17738] Description:
Bring revisions 17649, 17657 and 17658 from trunk to 1.8 branch:
17649: Refactor v2 B-trees to pin the B-tree header in the cache instead
of using separate reference counted data structure.
17657: Refactor the v2 B-tree code to use an open & close call
internally, in preparation for making those part of the library
private APIs for dealing with v2 B-trees.
17658: Rename 'H5B2_t' -> 'H5B2_hdr_t' and 'bt2' -> 'hdr' in preparation
for make v2 B-tree open/close routines library private (instead
of static).
