[svn-r12258] Purpose:
Code checkpoint
Description:
Add in more fractal heap support for odd allocation patterns (entries that
are too large for various block sizes, etc.)
Broke out fractal heap code into more source code modules.
Refactored fractal heap test to make it more understandable and
maintainable for the long term.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (heping)
Linux 2.4/64 (mir)
Solaris 2.9 (shanti)
