e6ef54b31f Bug#31588: buffer overrun when setting variables
Buffer used when setting variables was not dimensioned to accomodate
trailing '\0'. An overflow by one character was therefore possible.
CS corrects limits to prevent such overflows.

Fix: raise an error if one attempts to set it to USC-2.

4ea05eae31 Bug #27792 query cache returns wrong result, with certain system variables
- Queries in the query cache are identified by the individual 
   characters in the query statement, the current database and 
   the current environment expressed as a set of system variable
   flags.
 - Since the set of environment flags didn't properly describe the
   current environment unexpected results were returned from the 
   query cache.
 - Query cache is now cleared when the variable ft_boolean_syntax is 
   updated.
 - An identification flag for the variable default_week_format is 
   added to the query cache record.
 
Thanks to Martin Friebe who has supplied significant parts of this patch.

224660d14a Bug#22645 LC_TIME_NAMES: Statement not replicated
Problem: replication of LC_TIME_NAMES didn't work.
Thus, INSERTS or UPDATES using date_format() always
worked with en_US on the slave side.
Fix: adding ONE_SHOT implementation for LC_TIME_NAMES.

ee0cebf9a7 BUG#21726: Incorrect result with multiple invocations of LAST_INSERT_ID.
Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures.  However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:

  - LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).

  - LAST_INSERT_ID() could return the value generated by current
    statement if the call happens after the generation, like in

      CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
      INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());

  - Redundant binary log LAST_INSERT_ID_EVENTs could be generated.

  and fix some of the warnings that this turns up (plus a bonus unrelated one).

518993312c A fix and a test case for Bug#16365 "Prepared Statements: DoS with
too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume 
100MB of RAM. Once this limit has been reached, the server will 
refuse to prepare a new statement and return ER_UNKNOWN_ERROR 
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared 
statements is now available through a global read-only variable 
@@prepared_stmt_count.
