commit 3dc29ff5846160060587d41f22868486ffd4e96e
Author: Lionel Elie Mamane <lionel at mamane.lu>
Date:   Wed Aug 6 15:17:13 2014 +0200

    fdo#82151 when constructing column object, replace m_aCurrentRow by a function
    
    The passed m_aCurrentRow becomes out-of-date as soon as the current row changes.
    This also hides an implementation detail of ORowSet to ORowSet(Data)Column.
    
    Functional squelch of the following master commits:
