specific to 5.0 version of the patch is motivated by the fact that a wrapper over 
MYSQLLOG::write can not help in 5.0 where query's charset is embedded into event instance in the constructor.


sql/mysql_priv.h:
  this 4.1 specific code does not help in 5.0
sql/sql_base.cc:
  No wrapper similar to 4.1's version is done since Query_log_event constructor
  takes care of encodings in 5.0 whereas log::write method does it in 4.1.
  We can introduce an additional constuctor for Query_log_event to pass desired
  (i.e system_character_info) charset different from THD's version.
  But I am delaying this while there are not more bugs similar to this one reported.

  A pattern to generate binlog for DROPped temp table in close_temporary_tables
  was buggy: could not deal with a grave-accent-in-name table.

  The fix exploits `append_identifier()' for quoting and duplicating accents.

  I hope to become much simplier than previously. No-binlog branch is separated completely the
  rest that adopts String's methods.

  Add test case for bug#14635.
sql/item.cc:
  Add implementations of set_value() and set_required_privilege() methods
  of Settable_routine_parameter interface.
  
  Use Item_trigger_field::want_privilege instead of
  Item_trigger_field::access_type.
  
  Reset privileges on Item_trigger_field::cleanup().
sql/item.h:
  Add interface class Settable_routine_parameter and interface query
  method to Item class.  Item_splocal and Item_trigger_field implement
  this interface.
  
  For Item_trigger_field:
   - add read_only attribute and is_read_only() method.
   - remove access_type and add original_privilege and want_privilege
     instead.
   - add set_value() method.
   - add reset_privilege() method.
sql/item_func.cc:
  Add implementations of set_value() method of Settable_routine_parameter
  interface.
sql/item_func.h:
  Item_func_get_user_var implements Settable_routine_parameter interface.
sql/share/errmsg.txt:
  Update english ER_SP_NOT_VAR_ARG message.
sql/sp_head.cc:
  Use Settable_routine_parameter interface for parameter update.
sql/sql_yacc.yy:
  Set read_only and want_privilege members in Item_trigger_field
  appropriately.  For NEW.x trigger variable used in left-hand-side
  of SET statement the latter is set to UPDATE_ACL, otherwise it is
  set to SELECT_ACL (but see Item_trigger_field::set_required_privilege(),
  where it may be updated to different value).
