This may lead to buffer overflow.
The String::qs_append() function will append a string
without checking if there's enough space.
So qs_append() must be called beforehand to ensure 
there's enough space in the buffer for the subsequent 
qs_append() calls.
Fixed Item_case_expr::print() to make sure there's
enough space before appending data by adding a call to 
String::reserve() to make sure qs_append() will have 
enough space.

UPDATE if the row wasn't actually changed.

This bug was caused by fix for bug#19978. It causes AFTER UPDATE triggers
not firing if a row wasn't actually changed by the update part of the
INSERT .. ON DUPLICATE KEY UPDATE.

Now triggers are always fired if a row is touched by the INSERT ... ON
DUPLICATE KEY UPDATE.

 INSERT uses query_id to verify what fields are
 mentioned in the fields list of the INSERT command.
 However the check for that is made after the 
 ON DUPLICATE KEY is processed. This causes all
 the fields mentioned in ON DUPLICATE KEY to be 
 considered as mentioned in the fields list of 
 INSERT.
 Moved the check up, right after processing the
 fields list.

touched but not actually changed.

The LAST_INSERT_ID() is reset to 0 if no rows were inserted or changed.
This is the case when an INSERT ... ON DUPLICATE KEY UPDATE updates a row
with the same values as the row contains.

Now the LAST_INSERT_ID() values is reset to 0 only if there were no rows
successfully inserted or touched.
The new 'touched' field is added to the COPY_INFO structure. It holds the
number of rows that were touched no matter whether they were actually
changed or not.
