When running the REPL as standalone program it's now possible to use
`process.on('uncaughtException', listener)`. It is going to use those
listeners from now on and the regular error output is suppressed.
It also fixes the issue that REPL instances started inside of an
application would silence all application errors. It is now prohibited
to add the exception listener in such REPL instances. Trying to add
such listeners throws an `ERR_INVALID_REPL_INPUT` error.
