[svn-r13200] Purpose: Adding wrappers and fixing a bug

Description:
    - Added overloaded function DataType::copy to take a DataSet
    - Added overloaded DataType::commit
    - Fixed bugzilla 797
    - Fixed a warning in DataSpace::operator=
    - Set PropList parameter to default in DataType::convert

Platforms tested
    AIX 5.1 (copper)
    SunOS 5.8 64-bit (sol)
    HPUX 11.00 (kelgia)
