[svn-r7471] Purpose:
    Update

Description:
    The F_open and F_flush functions had a lot of cruft in them. The
    F_flush was being used as a way to allocate the superblock. The
    F_open had a bunch of code in there to read and serialize the
    superblock.

Solution:
    Moved these out into their own functions.

Platforms tested:
    Modi4 (parallel, Fortran)
    Copper (parallel, Fortran)
    Verbena (Fortran, C++)
    Sol (Fortran)

Misc. update:
