path names than 99 characters, using the USTAR format of the
resulting source TAR.

To be able to specify the use of USTAR when creating the source
TAR, we needed both to update the GNU autotools version requirements
slightly, and update the initiation of the tools to use more
modern constructs.

--default-character-set and --character-set-server such
that only the first will give a deprecation warning.
Apart from that, the two options should do the same.

The test case rpl_binlog_corruption fails on windows because when
adding a line to the binary log index file it gets terminated
with a CR+LF (which btw, is the normal case in windows, but not on
Unixes - LF). This causes mismatch between the relay log names,
causing mysqld to report that it cannot find the log file.

We fix this by creating the instrumented index file through
mysql, ie, using SELECT ... INTO DUMPFILE ..., as opposed on
relying on ultimatly OS commands like: -- echo "..." >
index. These changes go into the file and make the procedure
platform independent:

  include/setup_fake_relay_log.inc

Side note: when using SELECT ... INTO DUMPFILE ..., one needs to
check if mysqld is running with secure_file_priv. If it is, we do
it in two steps: 1. create the file on the allowed location;
2. move it to the datadir. If it is not, then we just create the
file directly on the datadir (so previous step 2. is not needed).

message:
  Bug #48321  CURRENT_USER() incorrectly replicated for DROP/RENAME USER;
              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).


mysql-test/r/select.result:
  Fix for bug#49897: crash in ptr_compare when char(0) NOT NULL 
  column is used for ORDER BY
    - test result.
mysql-test/t/select.test:
  Fix for bug#49897: crash in ptr_compare when char(0) NOT NULL 
  column is used for ORDER BY
    - test case.
sql/filesort.cc:
  Fix for bug#49897: crash in ptr_compare when char(0) NOT NULL 
  column is used for ORDER BY
    - assert added as filesort cannot handle null length sort data.
sql/sql_select.cc:
  Fix for bug#49897: crash in ptr_compare when char(0) NOT NULL 
  column is used for ORDER BY
    - don't sort null length data e.g. in case of ORDER BY CHAR(0).

sql/sql_test.cc:
  Assemble results of all the calls to full_name() first,
  in order not to garble the tabular output.

  in multitable delete/subquery

SQL_BUFFER_RESULT should not have an effect on non-SELECT 
statements according to our documentation.
Fixed by not passing it through to multi-table DELETE (similarly
to how it's done for multi-table UPDATE).

Rename method as to not hide a base.
Reorder attributes initialization.
Remove unused variable.
Rework code to silence a warning due to assignment used as truth value.
