[svn-r6057] Purpose:
    New Feature. Support for new FPHDF5 Feature
Description:
    More support for the FPHDF5 feature. This splits the H5D_create
    function into separate parts which update the metadata cache. It was
    necessary to split apart the H5O_create function to do a similar
    thing since it would allocate real space on the hard disk.

    I'm checking this up now so that I don't get too far away from what
    the CVS repository has and so that others may look at the code and
    retch^H^H^H^H^Hmarvel at it. If there are any comments, send them my
    way.

    There is one outstanding issue, though. I need to use non-API
    functions in the FPHDF5 stuff. I'm using some APIs right now and
    should migrate to using others. At the moment, I'm putting that on
    the back burner until I'm more along in the implementation.
Platforms tested:
    Arabica (C++)
    Eirene (Parallel)
    Modi4 (Parallel)
