[svn-r11967] Purpose:
New feature Description: Check in initial "fractal heap" code, for supporting the group redesign. Also, remove some remnants of the segmented heap/block tracker/B+tree code which I didn't find during the last pass. Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX (amazon) Linux 2.4
