The above query created a field of koi8r charset, not cp1251

Change:
CREATE TABLE a (a CHAR(1) CHARACTER SET utf8) 
Length now means character length, not byte length.
The above creates a field that guarantees can store a multibyte value
1 character long. For utf8 the above creates a field that can store
3 bytes.

fixed number of rows of external field reported to optimizer
added check of choosen key (checked left expression tag)
(SCRUM fix for simple IN optimisation)

  Code clean-up
sql_union.cc, union.test, union.result:
  A fix for a bug #978.
  This enables that NULL's can be entered into UNION's result set,
  although first SELECT columns are NOT NULL.
  This is also a start of fixing UNION's properly regarding type
  acceptance.
sql_select.cc:
  A commit for my second July SPRINT task

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.

CREATE TABLE t1 (s1 CHAR(5) CHARACTER SET latin1 COLLATE latin1_german2_ci);
INSERT INTO t1 VALUES ('Ü');
INSERT INTO t1 VALUES ('ue');
SELECT DISTINCT s1 FROM t1;

The above returned two rows in error.
Now it returns one row, in latin1_german2_ci:  Ü == ue

produced an error. This led to server crash in some cases, e.g.:
create table t7 (s1 char);
select * from t7
where concat(s1 collate latin1_general_ci,s1 collate latin1_swedish_ci)
= 'AA';

which are fixed now.
In 4.1 there are 3 calls; 2 of them will be fixed when there is a merge;
here I fix the 3rd, new one.
