Bug #6379: ENUM values are incorrectly converted

- add_field_to_list() now uses <List>String
instead of TYPELIB to be able to distinguish
literals 'aaa' and hex literals 0xaabbcc.
- move some code from add_field_to_list() where
  we don't know column charset yet, to 
  mysql_prepare_table(), where we do.
