[svn-r7037] Purpose:
    Bug fix

Description:
    The fill time in a dataset with no fill value information created with an
older version of the library was getting set to H5D_FILL_TIME_ALLOC instead of
the new default H5D_FILL_TIME_IFSET and was causing H5Dcreate() calls with that
dataset creation property list to fail now.

Solution:
    Set the new default in the fill time initialization for missing fill value
information.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
