tables or more

The problem was that the optimizer used the join buffer in cases when
the result set is ordered by filesort. This resulted in the ORDER BY
clause being ignored, and the records being returned in the order
determined by the order of matching records in the last table in join.

Fixed by relaxing the condition in make_join_readinfo() to take
filesort-ordered result sets into account, not only index-ordered ones.


mysql-test/r/select.result:
  Added a test case for bug #30666.
mysql-test/t/select.test:
  Added a test case for bug #30666.
sql/sql_select.cc:
  Relaxed the condition to determine when the join buffer usage must be
  disabled. The condition is now true for cases when the result set is
  ordered by filesort, that is when 'join->order &&
  !join->skip_sort_order' is true.

This is a 5.1 version of the patch.
  
Problem:
  
'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up
in SHOW VARIABLES, but could not be used in expressions like 
"select @@log". Also, using them in the SET statement produced an 
incorrect "unknown system variable" error.
  
Solution:

Since as of MySQL 5.1.12 one can enable or disable the general query log
or the slow query log at runtime by changing values of
general_log/slow_query_log, make 'log' and 'log_slow_queries" to be 
synonyms for 'general_log' and 'slow_query_log' respectively.  This 
makes expressions using the '@@var' syntax backward compatible with 
5.0 and SHOW VARIABLES output to be consistent with the SET statement.

  Added a test case for bug #29131.
mysql-test/t/log_state.test:
  Added a test case for bug #29131.
sql/set_var.cc:

This is a 5.0 version of the patch, it will be null-merged to 5.1

Problem:

'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up
in SHOW VARIABLES, but could not be used in expressions like 
"select @@log". Also, using them in the SET statement produced an 
incorrect "unknown system variable" error.

Solution:

Make 'log' and 'log_slow_queries' read-only dynamic variables to make 
them available for use in expressions, and produce a correct error 
about the variable being read-only when used in the SET statement.

Since, as of MySQL 5.0.15, CHAR() arguments larger than 255 are converted into multiple result bytes, a single CHAR() argument can now take up to 4 bytes. This patch fixes Item_func_char::fix_length_and_dec() to take this into account.
  
This patch also fixes a regression introduced by the patch for bug21513. As now we do not always have the 'name' member of Item set for Item_hex_string and Item_bin_string, an own print() method has been added to Item_hex_string so that it could correctly be printed by Item_func::print_args().

The special case with NULL as a regular expression
was handled at prepare time. But in this special case
the item was not marked as fixed. This caused an assertion
at execution time.
Fixed my marking the item as fixed even when known to 
return NULL at prepare time.

A sign of a resulting item of the IFNULL function was not
updated and the maximal length of this result was calculated
improperly. Correct algorithm was copy&pasted from the IF
function implementation.

  Fixed bug #31471.
  The Item_func_ifnull::fix_length_and_dec method has been
  modified to update the Item_func_ifnull::unsigned_flag field
  and to take this field into account when calculating the
  Item_func_ifnull::max_length value.
