Issuing error about presence of commit/rollback statements in stored functions and triggers added to SP parsing procedure (BUG#13627)

The crash mentioned in original bug report is already prevented by one
of previous patches (fix for bug #13343 "CREATE|etc TRIGGER|VIEW|USER
don't commit the transaction (inconsistency)"), this patch only improve
error returning.


mysql-test/r/sp-error.result:
  Test that statements which implicitly commit transaction
mysql-test/t/sp-error.test:
  Test that statements which implicitly commit transaction
sql/sp_head.cc:
  We set the new flag about commit/rollback statements presence
sql/sp_head.h:
  The new flag about commit/rollback presence added
  A comment fixed
sql/sql_yacc.yy:
  Removed commit/rollback-statement-present errors spread by this file, only one check left which check flags of a SP
