Quincey Koziol e5575571d4 [svn-r19396] Description: 
Bring back various modifications to the v2 B-trees that were introduced
in the revise_chunks branch but aren't dependent on any file format or API
changes.

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 (amani) 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, w/threadsafe, in production mode
        Linux/PPC 2.6 (heiwa) w/C++ & FORTRAN, w/threadsafe, in debug mode
        Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
                in production mode
        Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in debug mode
        Mac OS X/32 10.6.4 (amazon) in debug mode
        Mac OS X/32 10.6.4 (amazon) w/C++ & FORTRAN, w/threadsafe,
                in production mode

* Modifications:
* Robb Matzke, 1998-07-20
* Rearranged the message to add a version number at the beginning.
*
* Raymond Lu, 2002-2-26
* Added version number 2 case depends on if space has been allocated
* at the moment when layout header message is updated.
*
* Quincey Koziol, 2004-5-21
* Added version number 3 case to straighten out problems with contiguous
* layout's sizes (was encoding them as 4-byte values when they were
* really n-byte values (where n usually is 8)) and additionally clean up
* the information written out.
