            REVOKE/GRANT; ALTER EVENT.

The following statements support the CURRENT_USER() where a user is needed.
  DROP USER 
  RENAME USER CURRENT_USER() ...
  GRANT ... TO CURRENT_USER()
  REVOKE ... FROM CURRENT_USER()
  ALTER DEFINER = CURRENT_USER() EVENT
but, When these statements are binlogged, CURRENT_USER() just is binlogged
as 'CURRENT_USER()', it is not expanded to the real user name. When slave 
executes the log event, 'CURRENT_USER()' is expand to the user of slave 
SQL thread, but SQL thread's user name always NULL. This breaks the replication.

After this patch, All above statements are rewritten when they are binlogged.
The CURRENT_USER() is expanded to the real user's name and host.

Updated the certs to expire on 2015. 
Made sure they work with both yassl and openssl.

column is used for ORDER BY

Problem: filesort isn't meant for null length sort data
(e.g. char(0)), that leads to a server crash.

Fix: disregard sort order if sort data record length is 0 (nothing
to sort).

Define env. vars for both timeout settings
Also incorporated 5.0 patch into mtr version 1

printstack() being present

When Bug#47391 was fixed, no assumption was made that support
for Solaris 8 was needed. Solaris 8 lacks printstack(), and 
the build breaks because of this.

This patch adds a test for the presence of printstack() to
configure.in for 5.0, and uses HAVE_PRINTSTACK to make
decisions rather than the __sun define.

The 'rpl_get_master_version_and_clock' test verifies if the slave I/O
thread tries to reconnect to master when it tries to get the values of
the UNIX_TIMESTAMP, SERVER_ID from master under network disconnection.
So the master server is restarted for making the transient network
disconnection, during the period the COM_REGISTER_SLAVE failures are
produced in server log file when the slave I/O thread tries to
register on master.

To fix the problem, suppress COM_REGISTER_SLAVE failures in server log
file by mtr suppression, because they are expected.


mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result:
  Removed mtr.add_suppression("Get master clock failed with error: ")
  and mtr.add_suppression("Get master SERVER_ID failed with error: ").
  Because they are suppressed globally.

MySQL's hash functions MD5 and SHA relied on the somewhat slow 
sprintf function to convert the digests to hex representations.
This patch replaces the sprintf with a specific and inline hex
conversion function.

Patch contributed by Jan Steemann.

sql/item_strfunc.cc:
  Add a hex conversion function.

NOTE: added TODO to the comments requested by reviewer during this
      merge.

should be exited before destroying the thread local storage.

When replicating from 4.1 master to 5.0 slave START SLAVE UNTIL can stop too late.
The necessary in calculating of the beginning of an event the event's length
did not correspond to the master's genuine information at the event's execution time.
That piece of info was changed at the event's relay-logging due to binlog_version<4 event
conversion by IO thread.

Fixed with storing the master genuine Query_log_event size into a new status
variable at relay-logging of the event. The stored info is extacted at the event
execution and participate further to caclulate the correct start position of the event
in the until-pos stopping routine.
The new status variable's algorithm will be only active when the event comes
from the master of version < 5.0 (binlog_version < 4).


mysql-test/r/rpl_until.result:
  results changed.
mysql-test/std_data/bug47142_master-bin.000001:
  a binlog from 4.1 master to replace one of the running 5.x master is added as 
  part of Bug #47142 regression test.
mysql-test/t/rpl_until.test:
  Regression test for Bug #47142 is added.
sql/log_event.cc:
  Storing and extracting the master's genuine size of the event from the status
  var of the event packet header.
  The binlog_version<4 query-log-event is 
  a. converted into the modern binlog_version==4 to store the original size of the event
     into a new status var; the converted representation goes into the relay log.
  b. the converted event is read out and the stored size is engaged in the start pos calculation.
  
  The new status is active only for events that IO thread instantiates for the sake of the conversion.
sql/log_event.h:
  Incrementing the max szie of MAX_SIZE_LOG_EVENT_STATUS because of the new status var;
  Defining the new status variable to hold the master's genuine event size;
  Augmenting the Query_log_event with a new member to hold a value to store/extact from the status
  var of the event packet header.
