[svn-r12424] Purpose:

    Code checkpoint

Description:
    Add in more new features for the fractal heap code, mostly bringing in
more ability for deleting objects (which isn't completely working yet).

    Also, checkpoint free space manager code, which is essentially complete
(although it needs some more work after the metadata cache has some additional
features)

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Linux 2.4 (chicago)
    h5committest
