Implement IGNORE indicator for bulk operation parameters as was with DEFAULT.

For implementing SQL_COLUMN_IGNORE in odbc https://msdn.microsoft.com/en-us/library/ms711010(v=vs.85).aspx

For INSERT & REPLACE it will insert default value.

To make possible printing statements with ignored parameters with having legal index we also implement IGNORE "function" with no parameters (same as DEFAULT syntax) for UPDATE/INSERT/REPLACE.
