The error message due to lack of the default value for an extra field
was not as informative as it should be.

Fixed with improving the scheme of gathering, propagating and reporting
errors in applying rows events. 
The scheme is in the following.
Any kind of error of processing of a row event incidents are to be 
registered with my_error().
In the end Rows_log_event::do_apply_event() invokes rli->report() with the 
message to display consisting of all the errors.
This mimics `show warnings' displaying.
A simple test checks three errors in processing an event.
Two hunks - a user level error and pushing it into the list - 
have been devoted to already fixed Bug@31702.

Some open issues relating to this artifact listed on BUG@21842 page and
on WL@3679.
Todo: to synchronize the statement in the tests comments on Update and Delete
events may not stop when an extra field does not have a default with wl@3228 spec.

Problem: When slave reads format_description_log_event, it checks if the
master is a version that uses an old binlog format. See also BUG#27779.
Not all possible server_versions were listed.
Fix: Check for all server_versions which use the old binlog_format.

Here is the scenario that causes the failure.(by Mats)

1. The to-be corrupt log event (let's call it X), is split into two
   packets B and C on the network level (net_write_buff()). The parts
   are X = (x',x''). The part x' ends up in packet B and part x''
   ends up in packet C. Prior to the corrupt event X, the event Y has
   been written successfully, but has been split into two packets as
   well, which we call (y',y'').
2. The master sends packet A = (y'',x') to the slave, increases the
   packet sequence number, the slave receives the packet, but fails
   to reply before the master gets a timeout.
3. Since the master got a timeout, it reports failure, and aborts
   sending the binary log by exiting mysql_binlog_send(). However, it
   leaves the buffer intact, still holding y'' (but not x', since the
   write_pos is not increased).
4. After exiting mysql_binlog_send(), the master does a
   disconnection of the client thread, which involves sending an
   error message e to the client (i.e., the slave).
5. In this case, net_write_buff() is used again, but this time the
   old contents of the packet is used so that the new packet is
   D = (y'',e). Note that this will use a new packet sequence number,
   since the packet number was increased in step 2.
6. The slave receives the tail y'' of the Y log event, concatenates
   this with x' (which it already received), and writes the event
   (x',y'') it to the relay log since it hasn't noticed anything is
   amiss.
7. It then tries to read more bytes, which is either e (if the length
   given for X just happened to match the length given for Y, or just
   plain garbage because the slave is out of sync with what is
   actually sent.
8. After a while, the SQL thread tries to execute the event (x',y''),
   which is very likely to be just nonsense.

The problem can be fixed by not resetting net->error after the call of 
mysql_binlog_send, so the error message will not be sent and the connection
will be closed.

The problem is when create/rename/drop users, the statement was logged regardless of error, even if no data has been changed, the statement was logged.

After this patch, create/rename/drop users don't write the binlog if the statement makes no changes, if the statement does make any changes, log the statement with possible error code.

This patch is based on the patch for BUG#29749, which is not pushed

Mask binlog positions, error, warning and other information that are not significant for the test

Problem: Replication fails when master is mysql-5.1-wl2325-5.0-drop6 and
slave is mysql-5.1-new-rpl. The reason is that, in
mysql-5.1-wl2325-5.0-drop6, the event type id's were different than in
mysql-5.1-new-rpl.
Fix (in mysql-5.1-new-rpl):
 (1) detect that the server that generated the events uses the old
format, by checking the server version of the format_description_log_event
This patch recognizes mysql-5.1-wl2325-5.0-drop6p13-alpha,
mysql-5.1-wl2325-5.0-drop6, mysql-5.1-wl2325-5.0, mysql-5.1-wl2325-no-dd.
 (2) if the generating server is old, map old event types to new event
types using a permutation array.

I've also added a test case which reads binlogs for four different
versions.
