branches/6.0: Allow the minimum length of a multi-byte character to be
up to 4 bytes. (Bug #35391)
dtype_t, dict_col_t: Replace mbminlen:2, mbmaxlen:3 with mbminmaxlen:5.
In this way, the 5 bits can hold two values of 0..4, and the storage size
of the fields will not cross the 64-bit boundary. Encode the values as
DATA_MBMAX * mbmaxlen + mbminlen. Define the auxiliary macros
DB_MBMINLEN(mbminmaxlen), DB_MBMAXLEN(mbminmaxlen), and
DB_MINMAXLEN(mbminlen, mbmaxlen).
Try to trim and pad UTF-16 and UTF-32 with spaces as appropriate.
Alexander Barkov suggested the use of cs->cset->fill(cs, buff, len, 0x20).
ha_innobase::store_key_val_for_row() now does that, but the added function
row_mysql_pad_col() does not, because it doesn't have the MySQL TABLE object.
