29ffcad226 Fixed that LEFT OUTER JOIN was replaced with a regulat join 
in some cases, because "charset(x) = 'string'" was considered
as "x is not null" due to incorrect not_null_tables().

a7b877df78 Bugs#9129: CHARSET(), COLLATION(), COERCIBILITY() 
not always correct for NULL values.
Now they always result a non NULL value even
the argument is NULL. It is more usefull for 
debugging purposes.

7e8e033290 type_blob.result, func_system.result, func_str.result, ctype_collate.result: 
fixing test results accordingly.
func_system.test:
  New test that illegal mix of collations does not happen anymore.
item_strfunc.h:
    safe_charset_converter() was added for system constants.
item_strfunc.cc:
  safe_charset_converter() was added for system constants.
item_func.cc, item.h, item.cc:
  Bug#8291: Illegal collation mix with USER() function.
  After discussion with PeterG and Serge, a new coercibility
  level for "system constants" was introduced, between
  COERRIBLE and IMPLICIT. Thus:
  SELECT col1 = USER() FROM t1; - is done according to col1 collation.
  SELECT 'string' = USER(); - is done according to USER() collation.
  At the same time, "nagg" and "strong" members were removed as unused.
item_create.cc:
  Version is a system constant too.

mandates that the function result must be also NULL.
