Add all HA error numbers and descriptions to perror.

Add reminder to header.

This is already fixed in smarter ways in future codebases, and this 
codebase is unlikely to change, since new development is forbidden
here.

  
Signed integer format specifier forced to print the binlog header with server_id
negative if the unsigned value sets the sign-bit ON.
  
Fixed with correcting the specifier to correspond to typeof(server_id) == ulong.

mysql-test/r/mysqlbinlog.result:
  results changed.
mysql-test/t/mysqlbinlog.test:
  displaying the expected unsignedly formatted server_id value, bug#37313.
sql/log_event.cc:
  Format specifier is corrected to correspond to typeof(server_id).

Moved the test case for the bug into a separate file (and restored the 
original innodb_mysql test setup).

Re-enabling mysqlbinlog.test on Windows - removed the use of grep/sed

Replaced Unix calls with mysql-test-run's built-in functions / SQL manipulation where possible.
Replaced error codes with error names as well.
Disabled two tests on Windows due to more complex Unix command usage

The problem is that tables can enter open table cache for a thread without 
being properly cleaned up. This can happen if make_join_statistics() fails 
to read a const table because of e.g. a deadlock. It does set a member of 
TABLE structure to a value it allocates, but doesn't clean-up this setting 
on error nor does it set the rest of the members in JOIN to allow for 
automatic cleanup.
As a result when such an error occurs and the next statement depends re-uses 
the table from the open tables cache it will get it with this 
TABLE::reginfo.join_tab pointing to a memory area that's freed.
Fixed by making sure make_join_statistics() cleans up TABLE::reginfo.join_tab 
on error.

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.


mysql-test/r/row.result:
  test result
mysql-test/t/row.test:
  test case
sql/item.cc:
  added agg_item_set_converter() function which was a part of
  agg_item_charsets() func. The only difference is that
  agg_item_set_converter() checks and converts items 
  using already known collation.
sql/item.h:
  added agg_item_set_converter() function
sql/item_cmpfunc.cc:
  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.

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().


sql/item.cc:
  Multiply string's length in characters by charset's mbmaxlen when 
  calculating max_length.
tests/mysql_client_test.c:
  Added a test case for bug #41078.

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

  Remove test case result.

  Remove test case.

      
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.

  Fixed String::realloc() to check whether the existing string data fits
  in the newly allocated buffer for cases when reallocating a String
  object with external buffer.

  Added a test case for bug #41868.
sql/sql_class.cc:
  After each call to Item::send() in select_send::send_data() reset
  buffer to its original state to reduce unnecessary malloc() calls. See
  comments for bug #41868 for detailed analysis.
sql/sql_string.cc:
  Fixed String::realloc() to check whether the existing string data fits
  in the newly allocated buffer for cases when reallocating a String
  object with external buffer.

The parser was not using the correct fully-qualified-name
production for DROP FUNCTION.
Fixed by copying the production from DROP PROCEDURE.

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.
