[svn-r16794] Description:

    Fixed to pass parameters to H5Awrite/H5Aread correctly so that
    all Attribute::write and Attribute::read methods work correctly
    for both fixed-length and variable-length string attributes.

    Added more test cases.

Platforms tested:
    Linux/32 2.6 (jam)
    FreeBSD/64 6.3 (liberty)
