[svn-r11060] Purpose: Fix bug (reported by user)

Description:
    The use of FileCreatPropList::DEFAULT sometimes caused failure
    in the reference counting area.  This occurs to all the default
    property lists, which also include FileAccPropList::DEFAULT,
    DSetCreatPropList::DEFAULT, and DSetMemXferPropList::DEFAULT.
    H5P_DEFAULT was used to create these default prop lists and
    because its value is 0, the id of these prop lists are 0, which
    is rejected by the H5I functions during the reference counting.

Solution:
    The main action to fix the above problem was to use
        H5P_FILE_CREATE
        H5P_FILE_ACCESS
        H5P_DATASET_CREATE
        H5P_DATASET_XFER
    to define the default property lists accordingly.  Yet, when this
    fix was applied, some bug in reference counting was revealed.
    It appeared that some ids were not incremented but were passed in
    for decrementing.  The following actions were then taken to fix and
    improve the current use of reference counting H5I functions.

        * added private func IdComponent::p_valid_id to verify that the
          id is a valid id and can be passed into an H5I function
        * used p_valid_id to validate an id before calling an H5I functions
          in the reference-counting member functions incRefCount,
          decRefCount, and getCounter
        * changed to use member function incRefCount, decRefCount, and
          getCounter instead of the C APIs H5Iinc_ref, H5Idec_ref, and
          H5Iget_ref throughout IdComponent.

    In addition, overloadings were added for incRefCount, decRefCount,
    and getCounter to take an id different than the id of the current
    instance; they can be convenient during debugging.

Platforms tested:
    Linux 2.4 (heping)
    SunOS 5.8 64-bit (sol)
    AIX 5.1 (copper)
