e0a0790ebb Fixed that multibyte charsets didn't honor multibyte 
sequence boundaries in functions LIKE and LOCATE in
the case of "binary" collation. Comparison was done
like if the strings were just a binary strings without
character set assumption.

708ddc3a3b Fix: 
CREATE TABLE t1 (s1 CHAR(5) COLLATE latin1_german2_ci);
INSERT INTO t1 VALUES ('Ü');
SELECT FIELD('ue',s1) FROM t1;
The above returned 0 in error.
Now 1 is returned.

544f96f0fe fix_fields recoursion didn't stop when some level's fix_length_and_dec 
produced an error. This led to server crash in some cases, e.g.:

select * from t7
where concat(s1 collate latin1_general_ci,s1 collate latin1_swedish_ci)
= 'AA';
