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