  Bug#25822 / WL#3953 - Log Access Denied errors for bad passwords in the error log
  
  Added logging of Access Denied messages on failed new connections to the 
  error log when log-warnings = 2.
  
  This allows a user to log these messages without having to incur the overhead
  of using the general query log on production systems.

During insert, we are not reading the rows in a referring table but
instead using the last read row that happens to be in table->record[0].

Now INSERT into such view is denied.

(from revid:sergefp@mysql.com-20081227013233-f9n2by8romt37hyi)

(from revid:sergefp@mysql.com-20090126194259-ue20il3qro529l4d).
Compared to 6.0 where EXPLAIN indicates "Using index condition", here in join_optimizer.result
we see "Using where"; it's normal; 6.0 shows the same if disabling Index Condition Pushdown.

EXPLAIN EXTENDED warning.

Query optimizer searches for the constant tables and optimizes them away. This
means that fields of such tables are substituted for their values and on later
phases they are treated as constants. After this constant tables are removed
from the query execution plan. Nevertheless constant tables were shown in 
the EXPLAIN EXTENDED warning thus producing query that might be not an
equivalent of the original query.
        
Now the print_join function skips all tables that were optimized away from
printing to the EXPLAIN EXTENDED warning. If all tables were optimized away it
produces the 'FROM dual' clause.

  EXPLAIN EXTENDED warning.
  Now the print_join function skips all tables that were optimized away from

  produces the 'FROM dual' clause.
sql/table.h:
  Adjusted test case result after fix for the bug#30302.
  The optimized_away flag is added to the TABLE_LIST struct.

Fix a regression that crept in when downporting Windows improvements.
Instead of a shutdown thread, another thread that  handledsocket connection was created.

Ensure full path to dtrace binary is used, fixes builds where

Bug #33629: last_day function can return null, but has 'not null' flag set for result

LAST_DAY and MAKEDATE functions are documented as
returning NULL value, but actually they was implemented
as returning NOT NULL typed values.

That caused a confusing error "ERROR 1048 (23000): Column
'...' cannot be null" on queries like: 

  SELECT 1 FROM (SELECT LAST_DAY('0')) a;


mysql-test/r/func_sapdb.result:
    Updated test case for bug #33629.
mysql-test/r/func_time.result:
    Updated test case for bug #33629.
mysql-test/r/type_date.result:
    Added test case for bug #33629.

    Added test case for bug #33629.
sql/item_timefunc.h:
    Bug #33629: last_day function can return null, but has 'not null' flag set for result
    
    1. The Item_func_makedate::fix_length_and_dec method
       has been modified to declare MAKEDATE() as a function
       returning nullable value.
    2. The Item_func_last_day::fix_length_and_dec method
       has been overloaded for the same purpose.

sql/sql_plugin.cc:
  generate the key correctly using key_copy.
  field->store() stores the value in record format, not key format.

message:
  Fix for Bug#40128: drop-no_root fails under windows in 6.0-rpl.
  
  The problem was that directories with no permission (000) files
  are deleted differently on UNIX and on Windows.
  
  On UNIX, 000-permission file is deleted perfectly, but other files
  are left in the directory.
  
  On Windows, 000-permission file is not deleted, but other files
  are deleted.
  
  Also, the fix needed a change in mysqltest.c: 'chmod' directive
  should return a positive error code (in order to be handled).
  It's decided to return a constant '1' for all error codes
  just to be OS-independent.

message:
  A fix for Bug#26704: Failing DROP DATABASE brings
  mysql-client out of sync.

  The problem was that we changed current database w/o caring
  whether it was dropped successfully or not.

  The fix is not to change current database if we failed to drop it.
