Fixed bug #13191.
INSERT...ON DUPLICATE KEY UPDATE may cause error 1032:
"Can't find record in ..." if we are inserting into
InnoDB table unique index of partial key with
underlying UTF-8 string field.
This error occurs because INSERT...ON DUPLICATE uses a wrong
procedure to copy string fields of multi-byte character sets
for index search.
mysql-test/t/innodb_mysql.test:
Added test case for bug #13191.
mysql-test/r/innodb_mysql.result:
Added test case for bug #13191.
sql/field.h:
Fixed bug #13191.
Field_string::get_key_image() virtual function was overloaded
to implement copying of variable length character (UTF-8) fields.
Field::get_key_image() function prototype has been changed to
return byte size of copied data.
sql/field.cc:
Fixed bug #13191.

INSERT...ON DUPLICATE KEY UPDATE may cause error 1032:
"Can't find record in ...".
This error occurs because INSERT...ON DUPLICATE uses
a wrong procedure to copy field parts for index search.
key_copy() function has been fixed.
