[svn-r7072] Purpose:
    Bug fix & code cleanup

Description:
    The H5F_get_objects_cb was returning SUCCEED (i.e. 0) to indicate that
the ID iterator should exit early, but the ID iterator needs a non-zero return
from a callback to exit early.

    Also, track change to ID iterator "operator data" to be non-const

Solution:
    Changed H5F_get_objects_cb() to return "TRUE" instead, to indicate an
early exit for the ID iterator.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
