Fix Bug#38249 innodb_log_arch_dir still in support files
Remove a non-supported variable from cnf file templates.

- Since we are only using the auto cleanup in one place of mtr.pl today, disable the
autocleanup and write our own END handler that clean up the tmpdir only when the process
that created it exits.

      
Additional fix:
 1. Revert the unification of DROP FUNCTION
and DROP PROCEDURE, because DROP FUNCTION can be used to
drop UDFs (that have a non-qualified name and don't require
database name to be present and valid).
 2. Fixed the case sensitivity problem by adding a call to 
check_db_name() (similar to the sp_name production).

            
A Query in the MyISAM merge table was crashing 
if the index merge algorithm was being used

Index Merge optimization requires the reading of 
multiple indexes at the same time. Reading multiple 
indexes at once with current SE API means that we 
need to have handler instance for each to-be-read 
index. This is done by creating clones of the handlers 
instances. The clone internally does a open of the handler.

The open for a MERGE engine is handled in the following 
phases

1) open parent table
2) generate list of underlying
   table
3) attach underlying tables

But the current implementation does only the first 
phase (i.e.) open parent table.

The current patch fixes this at the MERGE engine level, 
by handling the clone operation within the MERGE engine 
rather than in the storage engine API. It opens and 
attaches the MyISAM tables on the MyISAM storage engine 
interface directly within the MERGE engine. The new MyISAM 
table instances, as well as the MERGE clone itself, are not 
visible in the table cache. This is not a problem because
all locking is handled by the original MERGE table from which
this is cloned of.

      
MATCH() function accepts column list as an argument. It was possible to override
this requirement with aliased non-column select expression. Which results in
server crash.

With this fix aliased non-column select expressions are not accepted by MATCH()
function, returning an error.

      
The test case relies on binlog entries for assertion. The problem is that the
binlog does not get cleaned in pushbuild between tests, resulting in extra
entries in the result file, causing the test to fail.
      
This fix adds a reset master at the beginning of the test, so that we get a
clean binlog file.

Reviewed fix for bug#40882: Replaced "sleep 1" by wait_condition, added save/restore start values and closed open sessions. When trying to use "wait_for_query_to_succeed" a type has been fixed, also in "rename.test": Added session count and check and replaced error numbers.

TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.

Correcting some tests that was failing in pushbuild as well as fixing result
file for some tests that are not executed in the default MTR run.

Post-merge fixes. Changes to some result sets.

The check for root-ness would signal an error.  Errors would make the
server exit before usage (help) information was printed.

Now, test for whether we want help regardless of whether we're going
to exit with an error.  If plugins are not initialized by the time we 
print usage information, inform the user that some parameters are 
missing.

There is an inconsistency with DROP DATABASE IF EXISTS, DROP
TABLE IF EXISTS and DROP VIEW IF EXISTS: those are binlogged even
if the DB or TABLE does not exist, whereas DROP PROCEDURE IF
EXISTS does not. It would be nice or at least consistent if DROP
PROCEDURE/STATEMENT worked the same too.
      
Fixed DROP PROCEDURE|FUNCTION IF EXISTS by adding a call to
write_bin_log in mysql_execute_command. Checked also if all
documented "DROP (...) IF EXISTS" get binlogged. Left out DROP
SERVER IF EXISTS because it seems that it only gets binlogged when
using row event (see BUG#25705).

Perl crashes when MTR 2 tries to start v1
Replaced require with system()

The parser was not using the correct fully-qualified-name
production for DROP FUNCTION.
Fixed by copying the production from DROP PROCEDURE.
Tested in the windows specific suite to make sure it's 
tested on a case-insensitive file system.

Bug#42003 tests missing the disconnect of connections <> default
second slice
Content:
1. wait_until_count_sessions.inc
   - One PB run of a test using this routine failed because
     5 seconds timeout were exceeded. Although I have some doubts
     if the assigned timeout was really too small, I increase the
     value to 10. We waste the additional 5 seconds only if the
     tests fails anyway.
   - Print the content of the PROCESSLIST if the poll routine fails
2. minor improvements of formatting
3. query_cache_notembedded:
   Activate the wait_until_count_sessions.inc routine which was
   unfortunately forgotten in the changeset before.
