When a user selected an unsupported character set for an
IBMDB2I table, error 2501 or 2511 may have been returned,
giving the appearance of an internal programming error.

This patch consolidates these errors into a single descriptive
error message for the common case of an unsupported character
set.

The new error number is 2504 and indicates a user error.
The errors 2501 and 2511 remain to indicate cases of internal
programming errors.

Problem: case conversion erroneously changes the second bytes
of multi-byte sequences because single-byte functions were
called in a mistake.
Fix: call multi-byte aware functions instead.

removed few sprintf's

'INSERT ... SELECT' statements

Merge

'INSERT ... SELECT' statements
            
The code that produces result rows expected that a duplicate row
error could not occur in INSERT ... SELECT statements with 
unfulfilled WHERE conditions. This may happen, however, if the 
SELECT list contains only aggregate functions.
Fixed by checking if an error occured before trying to send EOF
to the client.

  Bug#44306: Fix

A backport of fix for "BUG40092 - Storage engine API uses
time_t datatype".

Starting from MSVC C++ 2005 (v8), the default size of time_t
is changed from 32-bit to 64-bit. As the result, the binaries
built with pre-v8 MSVC C++ do not work with the binaries
(storage engine plugins) built with v8 or after (server
crashes).

Fixed storage engine API to use datatype with known size
(ulong) instead of time_t.

sql/handler.h:
  Bug#39802 On Windows, 32-bit time_t should be enforced
  
  Change create_time, check_time, update_time
  in the ha_statistics and PARTITION_INFO
  structures to ulong.

1. Replace waiting of SQL thread stop by waiting of SQL error on slave and stopped
SQL thread.
2. Remove debug code because it already implemented in MTR2.

EXPLAIN EXTENDED of nested query containing a error:

   1054 Unknown column '...' in 'field list'

may cause a server crash.


Parse error like described above forces a call to
JOIN::destroy() on malformed subquery.
That JOIN::destroy function closes and frees temporary
tables. However, temporary fields of these tables
may be listed in st_select_lex::group_list of outer
query, and that st_select_lex may not cleanup them
properly. So, after the JOIN::destroy call that
st_select_lex::group_list may have Item_field
objects with dangling pointers to freed temporary
table Field objects. That caused a crash.

my_error() was invoked in reset_slave()'s with purge_relay_logs()-failing branch

Fixed with setting sql_errno= ER_RELAY_LOG_FAIL in the purge_relay_logs()-failing branch.
