[svn-r2735] Purpose:
    Bug fix
Description:
    Recent changes to H5FD_read() added a new argument of type of
    data to be written but the MPIO file driver call to H5FD_read()
    was not updated.  Also, the prototype of H5FD_read() in H5Fprivate.h
    was "screened out", thus the compiler could not detect the inconsistency.
    With the mismatched arguments, MPIO failed badly.
Solution:
    Update the H5FD_read() call with the new parameter.  Since the
    call is used by H5Dread call so far, it is hardcoded to use
    H5FD_MEM_DRAW as the value.  If the call is used besides for
    H5Dread, this parameter needs to be better defined.
    (Still need to fix the prototype being blocked off.)
Platforms tested:
    O2K -64 parallel.
