In the output from mysqlbinlog, incident log events were
represented as just a comment. Since the incident log event
represents an incident that could cause the contents of the
database to change without being logged to the binary log,
it means that if the SQL is applied to a server, it could
potentially lead to that the databases are out of sync.

In order to handle that, this patch adds the statement "RELOAD
DATABASE" to the SQL output for the incident log event. This will
require a DBA to edit the file and handle the case as apropriate
before applying the output to a server.

mysql-test/suite/binlog/t/binlog_incident-master.opt:
  Options file to cause server to generate an incident log
  event when executing a REPLACE.
mysql-test/suite/binlog/t/binlog_incident.test:
  Test to check that the incident log event is represented
  correctly in the output from mysqlbinlog.
sql/log_event.cc:
  The incident log event now ouput a "RELOAD DATABASE" instead
  of just a comment. RELOAD DATABASE is not an existing command
  and will generate a syntax error.

Turned off autocommit at the start of this test per Innobase recommendation.
Noted significant reduction in run time for this test w/ a minor increase in other tests' run-times.

NULL merge fix for BUG#43660 into 5.1 as the fix for this bug
is already applied in 5.1

                   for indexes of InnoDB table

Fixes by replacing the PRNG that is used to pick random pages with a 
better one. 

Also adds a configuration option "innodb_use_legacy_cardinality_algorithm"
to enable the fix only when the option is set.

The rpl_binlog_corruption test case was inject failures, specifically,
incidents with invalid numbers to see if the replication was failing
gracefully. However, this test was causing the following warning message
in Valgrind: "Conditional jump or move depends on uninitialised value(s)"
      
The patch fixes the problem by correctly initializing the m_inicident 
number.

mysqldump.test is designed to run with concurrent inserts
disabled. It is disabling concurrent inserts at the very
beginning of the test case, and re-enables them at the
bottom of the test. But for some reason (likely incorrect
merge) we enable concurrent inserts in the middle of the test.

The problem is fixed by enabling concurrent inserts only
at the bottom of the test case.

3 problems found with DES_ENCRYPT/DES_DECRYPT :

1. The max length was not calculated properly. Fixed in fix_length_and_dec()
2. DES_ENCRYPT had a side effect of sometimes reallocating and changing 
the value of its argument. Fixed by explicitly pre-allocating the necessary
space to pad the argument with trailing '*' (stars) when calculating the 
DES digest.
3. in DES_ENCRYPT the string buffer for the result value was not 
reallocated to the correct size and only string length was assigned to it. 
Fixed by making sure there's enough space to hold the result.

The crash was due to a null pointer present for select_lex while 
processing the view.
Adding a check while opening the view to see if its a child of a 
merge table fixed this problem.

  Updated result for the new test case.

Streamlined how we increase the size of our test table.
The new method shows run time decreased by ~60%.
This is not a guarantee that we will not see test timeouts (the random failures noted in the bug),
but it should significantly reduce the chances of this occurring.

Remember the acquired record locks per table handle (row_prebuilt_t)

The problem was that new lock types were being added without a
corresponding description. Since the lock types (enum values)
are used as indices to the description array, the descriptions
could be shifted depending on the lock type. The solution is to
ensure that every lock type has a correspondent description.
