[svn-r15046] Purpose: Fixed bugs

Description:
    The class hierarchy was revised to address the problem reported in
    bugzilla #1068.  Classes AbstractDS and Attribute are moved out of
    H5Object.  Class Attribute now multiply inherits from IdComponent and
    AbstractDs and class DataSet from H5Object and AbstractDs.

    In addition, data member IdComponent::id was moved into subclasses:
    Attribute, DataSet, DataSpace, DataType, H5File, Group, and PropList.

    Also fixed bugzilla 1045: revised Attribute::write and Attribute::read
    wrappers to handle memory allocation/deallocation properly. (bugzilla 1045)

Platforms tested:
    SunOS 5.10 (linew)
    Linux 2.6 (kagiso)
    FreeBSD (duty)
