Subject: [PATCH] (byte_table_description): Use `XD_LISP_OBJECT_ARRAY' instead
 of `XD_LISP_OBJECT'. (char_id_table_description): Delete
 bogus `, 1'. (Fget_char_attribute): Refer encoding_table of
 each coded-charset to get value of coded-charset attribute
 of a character. (Fput_char_attribute): Use
 `make_older_vector' instead of `make_vector'; use
 encoding_table of each coded-charset to store value of
 coded-charset attribute of a character.
 (Fremove_char_attribute): Use encoding_table of each
 coded-charset to store value of coded-charset attribute of
 a character. (mark_charset): Mark `cs->encoding_table';
 don't mark `cs->decoding_table'. (charset_description): Add
 description of new member `encoding_table'. (make_charset):
 Initialize `encoding_table'.
