[svn-r6402] Purpose:
    Update
Description:
    Added the flush function.

    Modified so that it calls the FPHDF5 code for reading and writing.
    This involved splitting the write function up into three different
    parts to avoid lame goto's. There's some code which will copy a data
    xfer property list and add in there that we're "dumping" the data so
    that we can recall this layer when the SAP dumps metadata to a
    process...
Platforms tested:
    Linux
