[svn-r7087]

Purpose:
    Review feedback.
    Change "Development notes" to user notes.
    New fill_time value (H5D_FILL_TIME_IFSET).
    Formatting fix and copy edits.

Description:
    (Based primarily on review feedback and developer consultations)
    H5Pset_hyper_vector_size -- Clarification on timing.
    H5Pmodify_filter -- dapl .vs. dcpl clarification.
    H5Pset_filter_by_id -- dapl .vs. dcpl clarification.
    H5Pset_szip -- Copy edits.
    5Pset_fill_time -- Added new fill_time value, H5D_FILL_TIME_IFSET.

    H5Pset_fill_value, H5Pfill_value_defined,
    H5Pset_fill_time, H5Pset_alloc_time
         -- Added H5Dcreate x-ref to "Notes."

    H5Pcreate_class, H5Pregister, H5Pinsert
        -- Convert some "development notes" to user notes; delete others.
        -- Formatting rework in H5Pregister "Parameters."

Platforms tested:
    IE 5, Safari
