    A fix and a test case for Bug#11172 "mysql_stmt_attr_set · d36c14f7
    unknown authored
    CURSOR_TYPE_READ_ONLY date/datetime filter server crash".
    The fix adds support for Item_change_list in cursors (proper rollback
    of the modified item tree). 
    
    
    sql/sql_class.cc:
      No need to call fatal_error() twice.
    sql/sql_prepare.cc:
      - implement proper cleanup of the prepared statement in mysql_stmt_reset
        if there is a cursor.
      - take into account thd->change_list when fetching data through a
        cursor.
    sql/sql_select.cc:
      - take into account thd->change_list when fetching data from a cursor:
        grab it when we open a cursor, and rollback the changes to the parsed
        tree when we close it.
    sql/sql_select.h:
      - Cursor::change_list added
    tests/mysql_client_test.c:
      - a test case for Bug#11172 "mysql_stmt_attr_set CURSOR_TYPE_READ_ONLY date/datetime
       filter server crash"
