[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). Tested on: FreeBSD/32 6.3 (duty) in debug mode FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode Linux/32 2.6 (jam) w/PGI compilers, w/default API=1.8.x, w/C++ & FORTRAN, w/threadsafe, in debug mode Linux/64-amd64 2.6 (smirom) w/Intel compilers, w/default API=1.6.x, w/C++ & FORTRAN, in production mode Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN, w/szip filter, in production mode Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN, in production mode Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in debug mode Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in production mode Mac OS X/32 10.6.1 (amazon) in debug mode Mac OS X/32 10.6.1 (amazon) w/C++ & FORTRAN, w/threadsafe, in production mode
