The bug happened because filtering-out a STMT_END_F-flagged event so that
the transaction COMMIT finds traces of incomplete statement commit.
Such situation is only possible with ndb circular replication. The filtered-out
rows event is one that immediately preceeds the COMMIT query event.
      
Fixed with deploying an the rows-log-event statement commit at executing
of the transaction COMMIT event. 
Resources that were allocated by other than STMT_END_F-flagged event of
the last statement are clean up prior execution of the commit logics.

The original symptoms of this bug have been fixed as a consequence of other bug fixes.
Taking this time to correct some formatting, such as replacing error numbers with names.
Beginning this with 5.0

The patch adds restart of mysql server and replacing of binlog file 
when mysql server is stopped.

There are two issues: 
      1. 6.0 uses the obsolate master-*** server options;
      2. the test is not deterministic in that although master vs slave consistency is
         fine, two runs of the test can have different results. The reason of the
         non-determinism is the combination of 
         a chosen way to demo results and the ndb_autoincrement_prefetch_sz feature.

The current patch fixes the 2nd issue by putting out results via diff_table macro
instead of the former run-sensitive method.
The 1st issue is going to be fixed by a separate patch to 6.0.

Problem:
Custom UCA collations didn't set the MY_CS_STRNXFRM flag,
which resulted in "prefix_search" method instead of
the required "seq_search".

Problem2: (not metioned in the bug report)
Custom UCA collations didn't also set the MY_CS_UNICODE flag,
so an attempt to compare a column with a custom UCA collation
to another column with a non-Unicode character set led to
the "illegal mix of collation" error.

Fix:
the two missing flags was added into collation initialization.

  Upgrade:

  - All fulltext indexes with custom UCA collations should be rebuilt.

  - Non-fulltext custom UCA indexes should likely be rebuild as well.

Remove size of binlog file from SHOW BINARY LOGS. 
Changing size of binlog file is an affect of adding or removing events to/from
binlog and it can be checked in next command of test: SHOW BINLOG EVENTS.
For SHOW BINARY LOGS statement enough to show the list of file names.

fixed federated warnings

Changed [ skip ] to [ skipped ] and removed optional .

  1 - MASTER_MYSOCK fixed inexistent environment variable.
  2 - Fixed mismatch in result files due to changes in MTR.

      
It seems that the length of the thick line printed by mtr when printing the 
suite name differs from mtr1 and mtr2, affecting the mtr filtering by PB2.
      
This patch addresses it by restoring the thick line length to 78 (original
length) instead of 60 (the one in mtr2).

      
The test case proposed by the bugfix fails in bugteam trees after merging new 
mtr from main. The failure is due to the fact that the binlog file location has
changed and is no more under $MYSQLTEST_VARDIR/log.
      
This patch fixes the test failure by setting the correct path to the binlog 
file.

When storing a NULL to a TIMESTAMP NOT NULL DEFAULT ...,
NULL returned from some functions threw a 'cannot be NULL error.'

NULL-returns now correctly result in the timestamp-field being
assigned its default value.
