Bug 182695 Backport RowFetchLimit setting in model to 2.1.3
In 2.1.3 Model add new methods DataSetHandle.setDataSetRowLimit() and DataSetHandle.getDataSetRowLimit() to let user define the number of rows that returned from database. This however duplicate with existing 2.2 model methods DataSetHandle.setRowFetchLimit() and DataSetHandle.getRowFetchLimit(). Model should backport the changes to 2.1.3.
