Currently, we have Field and ColumnSchema to access column data in a row. These two classes are mostly the same. So we should unify these to one class. Now, Field has offset information, which is an row attribute, so we remove offset in Field. RowCursor now has some logic which belong to Schema, so in this patch I add Schema attribute to RowCursor to make RowCursor simple. After this change, only Schema will handle Field/ColumnSchema. I extract some logic from RowCursor to be/src/olap/row.h, then we can use same logic to handle different types of row. Each type of row has same function that to get Cell of this row. A cell represent a column content with a null indicator.
