lint: warn about function definitions without header declaration

The existing warning was only issued for function declarations, not for function definitions. The interesting change in the tests is in msg_351.c. Many other tests use non-static functions due to their syntactic brevity. In these tests, the warning is disabled individually, to allow new functions to be added without generating warning 351.
