In case of ROW item each compared pair does not
check if argumet collations can be aggregated and
thus appropiriate item conversion does not happen.
The fix is to add the check and convertion for ROW
pairs.

returns short string value. 
 
Multibyte character sets were not taken into account when 
calculating max_length in Item_param::convert_str_value(). As a 
result, string parameters of a prepared statement could be 
truncated later when calculating string length in characters by 
dividing length in bytes by the charset's mbmaxlen value (e.g. in 
Field_varstring::store()). 
 
Fixed by taking charset's mbmaxlen into account when calculating 
max_length in Item_param::convert_str_value().

      
Removed the misleading "NOTE:" from the \h command. 

replace wild_case_compare with my_wildcmp which is multibyte safe function

Dirty close tricky does not work on Windows.

      
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).

      
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.

String::realloc() did not check whether the existing string data fits in
the newly allocated buffer for cases when reallocating a String object
with external buffer (i.e.alloced == FALSE).  This could lead to memory
overruns in some cases.

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.

This involves just the tag, no file changes - they were all present before.

In 37553 we declared longlong results for
class Item_str_timefunc as per comments/docs,
but didn't add a method for that. And the
default just wasn't good enough for some
cases.

Changeset adds dedicated val_int() to class.

   - If missing: add "disconnect <session>"
   - If physical disconnect of non "default" sessions is not finished
     at test end: add routine which waits till this happened
+ additional improvements
  - remove superfluous files created by the test
  - replace error numbers by error names
  - remove trailing spaces, replace tabs by spaces
  - unify writing of bugs within comments
  - correct comments
  - minor changes of formatting
Fixed tests:
  backup
  check
  compress
  grant
  information_schema
  multi_update
  overflow
  packet
  query_cache_not_embedded
  sp-threads
  subselect
  synchronization
  timezone_grant
