[svn-r7805] Purpose:

    Bug Fix

Description:
    The End of Address information needed to be kept by the SAP. Some
    processes were trying to get the EOA information in collective mode,
    but the action wasn't collective at the time.

Solution:
    Keep the EOA information for the file on the SAP. Clients query the
    SAP to get/set it when needed.

Platforms tested:
    Linux (w/ FPHDF5)
    Copper (w/o FPHDF5)
    (FPHDF5 specific, so no need for full testing)
