mysql-test/r/sp.result:
  Test results fixed: rewritten test for Bug#6129
mysql-test/r/view.result:
  Push a change to the result file from Sanja's patch.
mysql-test/t/sp.test:
  Rewrite the test for Bug#6129 (now that stored procedures don't
  evaluate system variables at parse, the test produced different results).
  The old test failed with 1 in the second invocation (the old
  result was wrong).
sql/item_func.cc:
  After-merge fix.
sql/item_func.h:
  After-merge fix.
sql/mysql_priv.h:
  After-merge fix.
sql/mysqld.cc:
  Rollback the patch for Bug#7403 (it breaks the test suite).
