* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
newer testsuite). They are expected to go after mergning with the latest
xtradb.
assertion .\filesort.cc, line 797
A query with the "ORDER BY @@some_system_variable" clause,
where @@some_system_variable is NULL, causes assertion
failure in the filesort procedures.
The reason of the failure is in the value of
Item_func_get_system_var::maybe_null: it was unconditionally
set to false even if the value of a variable was NULL.

Bug #42778: delete order by null global variable causes
assertion .\filesort.cc, line 797
The longlong_from_string_with_check function has been modified
to skip unwanted warnings: now it uses the THD::no_errors
flag to suppress warnings.
The Item_func_get_system_var::update_null_value method
sets the no_error flag.
sql/item_func.cc:
Bug #42778: delete order by null global variable causes
assertion .\filesort.cc, line 797
1. The Item_func_get_system_var::fix_length_and_dec method
has been modified to make system variables truly nullable.
2. The Item_func_get_system_var::update_null_value method
method has been overloaded with a simple wrapper (like
Item_field::update_null_value) to suppress unwanted warnings
from Item_func_get_system_var::val_int() calls on non-numeric
variable values: the Item_func_get_system_var::update_null_value
method sets and restores THD::no_errors flag for a nested
call of the longlong_from_string_with_check function.

Bug #42778: delete order by null global variable causes

The Item_func_get_system_var::update_null_value method
method has been overloaded.
The problem is that creating a event could fail if the value of
the variable server_id didn't fit in the originator column of
the event system table. The cause is two-fold: it was possible
to set server_id to a value outside the documented range (from
0 to 2^32-1) and the originator column of the event table didn't
have enough room for values in this range.
The log tables (general_log and slow_log) also don't have a proper
column type to store the server_id and having a large server_id
value could prevent queries from being logged.
The solution is to ensure that all system tables that store the
server_id value have a proper column type (int unsigned) and that
the variable can't be set to a value that is not within the range.

Add test case for server_id value range.

Columns that store the server_id value must be of type INT UNSIGNED,
fix event (originator), general_log and slow_log (server_id) tables
in accordance.

Columns that store the server_id value must be of type INT UNSIGNED,
fix event (originator), general_log and slow_log (server_id) tables

sql/mysqld.cc:
Set min and max values for the server_id variable.
Unfortunately we can't easily change server_id variable type
from ulong to uint32 because of the sys_var classes.
Revised the test to include a test of completion_type = 1 as well as making the test more readable / worthwhile
Removed the master.opt file as it was redundant / unnecessary.
mysql-test/suite/sys_vars/t/completion_type_func-master.opt:
Removed as redundant. Test uses include/have_innodb.inc.
There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.
mysys/thr_mutex.c:
adding DBUG_PRINT here, so that we can locate where the warning is issued.

The minimum value differs depending on the OS and mysqld build, so that the test fail spradically.
The check of this value has been changed from check of concrete values to the check of a range that is near by the expected value.
which were determined by the server depending on the os. The solution is to disable warnings in general.
The check of the values only have been done for Linux and Windows. Now, the check has been changed to the check of
ranges (not more concrete values) being near by the expected (set) values.
