      Enable support of access to tables from triggers. Thus fix bug #8406 "Triggers · 14b1f91b
      unknown authored
      crash if referencing a table" and several other related bugs.
      Fix for bug #11834 "Re-execution of prepared statement with dropped function
      crashes server." which was spotted during work on previous bugs.
      
      Also couple of nice cleanups:
      - Replaced two separate hashes for stored routines used by statement with one.
      - Now instead of doing one pass through all routines used in statement for
        caching them and then doing another pass for adding their tables to table
        list, we do only one pass during which do both things.
      
      
      mysql-test/r/sp-error.result:
        Added test for bug #11834 "Re-execution of prepared statement with dropped
        function crashes server" also covering handling of prepared statements
        which use stored functions but does not require prelocking.
      mysql-test/r/sp.result:
        Updated test for LOCK TABLES with views in table list.
        (Old version of statement used in this test will work ok now, since prelocking
         algorithm was tuned and will lock only one multi-set of tables for each routine
         even if this routine is used in several different views).
      mysql-test/r/trigger.result:
        Added several tests for triggers using tables.
      mysql-test/t/sp-error.test:
        Added test for bug #11834 "Re-execution of prepared statement with dropped
        function crashes server" also covering handling of prepared statements
        which use stored functions but does not require prelocking.
      mysql-test/t/sp.test:
        Updated comment about recursive views to reflect current situation.
        Updated test for LOCK TABLES with views in table list.
        (Old version of statement used in this test will work ok now, since prelocking
         algorithm was tuned and will lock only one multi-set of tables for each routine
         even if this routine is used in several different views).
      mysql-test/t/trigger.test:
        Added several tests for triggers using tables.
      sql/item_func.cc:
        Item_func_sp::cleanup():
          By next statement execution stored function can be dropped or altered so
          we can't assume that sp_head object for it will be still valid.
      sql/sp.cc:
        - Added Sroutine_hash_entry structure that represents element in the set of
          stored routines used by statement or routine. We can't as before use
          LEX_STRING for this purprose because we want link all elements of this set
          in list.
        - Replaced sp_add_to_hash() with sp_add_used_routine() which takes into account
          that now we use one hash for stored routines used by statement instead of two
          and which mantains list linking all elelemnts in this hash.
        - Renamed sp_merge_hash() to sp_update_sp_used_routines().
        - Introduced sp_update_stmt_used_routines() for adding elements to the set of
          routines used by statement from another similar set for statement or routine.
          This function will also mantain list linking elements of destination set.
        - Now instead of one sp_cache_routines() function we have family of 
          sp_cache_routines_and_add_tables() functions which are also responsible for
          adding tables used by routines being cached to statement table list. Nice
          optimization - thanks to list linking all elements in the hash of routines
          used by statement we don't need to perform several iterations over this hash
          (as it was before in cases when we have added new elements to it).
      sql/sp.h:
        Added declarations of functions used for manipulations with set (hash) of stored
        routines used by statement.
      sql/sp_head.cc:
        sp_name::init_qname():
          Now sp_name also holds key identifying routine in the set (hash) of
          stored routines used by statement. 
        sp_head:
          Instead of two separate hashes sp_funs/m_spprocs representing sets of stored
          routines used by this routine we use one hash - m_sroutines. 
        sp_instr_set_trigger_field:
          Added support for subqueries in assignments to row accessors in triggers.
        Removed definition of sp_add_sp_tables_to_table_list() and auxilary functions 
        since now we don't have separate stage on which we add tables used by routines
        used by statement to table list for prelocking. We do it on the same stage as
        we load those routines in SP cache. So all this functionality moved to
        sp_cache_routines_and_add_tables() family of functions.
      sql/sp_head.h:
        sp_name:
          Now this class also holds key identifying routine in the set (hash) of stored
          routines used by statement. 
        sp_head:
          Instead of two separate hashes sp_funs/m_spprocs representing sets of stored
          routines used by this routine we use one hash - m_sroutines. 
        sp_instr_set_trigger_field:
          Added support for subqueries in assignments to row accessors in triggers.
        Removed declaration of sp_add_sp_tables_to_table_list() since now we don't have
        separate stage on which we add tables used by routines used by statement to
        table list for prelocking. We do it on the same stage as we load those routines
        in SP cache.
      sql/sql_base.cc:
        open_tables():
        - LEX::spfuns/spprocs hashes were replaced with one LEX::sroutines hash.
        - Now instead of doing one pass through all routines used in statement for
          caching them and then doing another pass for adding their tables to table
          list, we do only one pass during which do both things. It is easy to do
          since all routines in the set of routines used by statement are linked in
          the list. This also allows us to calculate table list for prelocking more
          precisely.
        - Now triggers properly inform prelocking algorithm about tables they use.
      sql/sql_lex.cc:
        lex_start():
          Replaced LEX::spfuns/spprocs with with one LEX::sroutines hash.
          Added LEX::sroutines_list list linking all elements in this hash.
        st_lex::st_lex():
          Moved definition of LEX constructor to sql_lex.cc file to be able
          use sp_sroutine_key declaration from sp.h in it.
      sql/sql_lex.h:
        LEX:
          Replaced two separate hashes for stored routines used by statement with one.
          Added list linking all elements in this hash to be able to iterate through all
          elements and add new elements to this hash at the same time.
          Moved constructor definition to sql_lex.cc.
      sql/sql_parse.cc:
        mysql_execute_command():
          Replaced LEX::spfuns/spprocs with one LEX::sroutines hash.
      sql/sql_trigger.cc:
        Added missing GNU GPL notice.
        Table_triggers_list::check_n_load()
          Added initialization of sroutines_key which stores key representing
          triggers of this table in the set (hash) of routines used by this statement.
      sql/sql_trigger.h:
        Added missing GNU GPL notice.
        Table_triggers_list:
          Added sroutines_key member to store key representing triggers of this
          table in the set (hash) of routines used by this statement.
          Declared sp_cache_routines_and_add_tables_for_triggers() as friend since
          it needs access to sroutines_key and trigger bodies.
      sql/sql_yacc.yy:
        - Now we use sp_add_used_routine() instead of sp_add_to_hash() for adding
          elements to the set of stored routines used in statement.
        - Enabled support of subqueries as right sides in assignments to triggers' row
          accessors.

      Fix for BUG#11211 "GROUP BY doesn't work correctly" · 476ca52e
      unknown authored
        
      When the GROUP BY clause contains a column reference that can be resolved to
      both an aliased column in the SELECT list, and to a column in the FROM clause,
      the group column is resolved to the column in the FROM clause (for ANSI conformance).
      However, it may be so that the user's intent is just the other way around, and he/she
      gets the query results grouped by a completely different column than expexted.
      This patch adds a warning in such cases that tells the user that there is potential
      ambiguity in the group column.
      
      sql/sql_select.cc
      - Added a warning when a GROUP column is ambiguous due to that there is a
        column reference with the same name both in the SELECT and FROM clauses.
        In this case we resolve to the column in FROM clause and warn the user
        of a possible ambiguity.
      - More extensive comments.
      - Changed the function to return bool instead of int (as in other places).
