[svn-r12349] Purpose:

    Code checkpoint

Description:
    Checkpoint fractal heap improvements, as well as move the free space
manager code that it's using into a separate package.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Linux 2.4/64 (mir) w/C++ & FORTRAN
    Linux 2.4/32 (heping)
    Solaris 2.9 (shanti)
    AIX 5.? (copper) w/FORTRAN & parallel
