corruption and crash results
      
An index creation statement where the index key
is larger/wider than the column it references 
should throw an error.
      
A statement like:
  CREATE TABLE t1 (a CHAR(1), PRIMARY KEY (A(255)))
did not error, but a segmentation fault followed when
an insertion was attempted on the table
      
The partial key validiation clause has been 
restructured to (hopefully) better document which
uses of partial keys are valid.

      
We found that there are some tests that are not cleaning
up properly:
      
  1. rpl_tmp_table_and_DDL
  2. rpl_do_grant
  3. rpl_sync
      
For #1 and #2 we found that the slave would not, for some
cases, replicate all the instructions the master processed 
in the cleanup section. We fix these by deploying some 
synchronization commands in the test cases so that slave 
processes all clean up instructions.
      
As for #3, this is tracked as part of another bug 
(BUG@50442).

Problem was that in mysql-trunk the ER() macro is now dependent on current_thd
and the innodb monitor thread has no binding to that thd object. This cause 
the crash because of bad derefencing.

Solution was to add a new macro which take the thd as an argument (which the innodb
thread uses for the call).

(Updated according to reviewers comments, i.e. added ER_THD_OR_DEFAULT and
moved test to suite parts.)

The number for MYSQL_REPLICATION_PLUGIN was shifted when backporting
because MYSQL_AUDIT_PLUGIN was not backported.

This problem is fixed by backporting only the number of audit plugin
and print an error when trying to load audit plugins. Note that
replication plugins compiled against old MYSQL_REPLICATION_PLUGIN
number will also be recognized as audit plugin and be rejected.

The IO thread can concurrently access the relay log IO_CACHE
while another thread is performing an FLUSH LOGS procedure.
      
FLUSH LOGS closes and reopens the relay log and while doing so it
(re)initializes its IO_CACHE. During this procedure the IO_CACHE
mutex is also reinitialized, which can cause problems if some
other thread (namely the IO THREAD) is concurrently accessing it
at the time .
      
This patch fixes the problem by extending the interface of the
flush_master_info function to also include a second paramater, 
"need_relay_log_lock", stating whether the thread should grab the 
relay log lock or not before actually flushing the relay log. 
Also, IO thread now calls flush_master_info with this flag set 
when it flushes master info with in the event read_event loop.

Finally, we also increase loop time in rpl_heartbeat_basic test 
case, so that the number of calls to flush logs doubles, stressing
this part of the code a little more.

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.
