    mysql-test/r/events.result:
      add a test for to test bug #16431
    mysql-test/t/events.test:
      results of new tests
    sql/event.cc:
      - more debug info
      - pass info to evex_remove_from_cache() whether the operation 
        was drop or alter. this fixes possible bug that may lead to dropping
        of an event when it's altered. also fix for bug#16431
    sql/event_executor.cc:
      be more verbose and throw more errors
    sql/event_timed.cc:
      - add ` around the names of the db and the event_name and not
      their concatenation. remove ; from the end - unneeded. this fixes bug #16431,
      which was failing because after some recursion the query was ending on ;;
      which is normally an error in the parser because that's the delimiter
      
      - more debug info
      - don't execute lex_end() two times when there's a parse error or thd->is_fatal_error
