Covert lib/net.js over to using lib/internal/errors.js - Replace thrown errors in lib/net.js with errors from lib/internal/errors. The ERR_INVALID_OPT_VALUE error have been used in the Server.prototype.listen() method - Update tests according to the above modifications PR-URL: #14782 Refs: #11273 Reviewed-By: Refael Ackermann <[email protected]> Reviewed-By: James M Snell <[email protected]> Reviewed-By: Ruben Bridgewater <[email protected]> Reviewed-By: Michael Dawson <[email protected]> Reviewed-By: Joyee Cheung <[email protected]>
