Fixed wrong key usage which caused wrong result for some "WHERE primary_key=constant" queries where MySQL could use 'only index' (Bug #3666)
The bug was introduced in a patch in the 4.1.2 source tree.

as the I/O thread filters on the server id, we must test replicate_same_server_id in it (on top of in the SQL thread).

SQL_SELECT_LIMIT as default will be applied only for SELECT statement if there was not explicit LIMIT clause
correct table list passed to class constructor of select_update

We didn't use 'only index' for tables of type 'const'. (Bug #3497)

(Bug #3596)

but used in a nested query.

Now test_bug1664() uses new statement checking macros.

"mysql_send_long_data() API call is completely broken".

Now we are resetting some members (long_data_supplied/null_value...) of Item_param to its 
initial state after each execution of prepared statement. We also manipulating 
Item_param::maybe_null/null_value only via Item_param::set_* setters which makes code a bit 
more robust.

just for beauty of truth.

in hard-coded replication messages, always put small-length info (error codes, explanation of the error) at the beginning,
so that it is not cut by truncation if the query is very long (which happens if the query goes first).

Fixed security problem that password was temporarly reset when someone changed GRANT for a user. (Bug #3404)
Fixed problem with PROCEDURE analyse() and impossible WHERE (Bug #2238)
Don't auto-repair tables in mysqlcheck if table type doesn't support 'check' command.

  a small fix for the test case

Hopefully last one
