errors: convert 'fs'
covert lib/fs.js over to using lib/internal/errors.js i have not addressed the cases that use errnoException(), for reasons described in GH-12926 - throw the ERR_INVALID_CALLBACK error when the the callback is invalid - replace the ['object', 'string'] with ['string', 'object'] in the error constructor call, to better match the previous err msg in the getOptions() function - add error ERR_VALUE_OUT_OF_RANGE in lib/internal/errors.js, this error is thrown when a numeric value is out of range - document the ERR_VALUE_OUT_OF_RANGE err in errors.md - correct the expected args, in the error thrown in the function fs._toUnixTimestamp() to ['Date', 'time in seconds'] (lib/fs.js) - update the listener error type in the fs.watchFile() function, from Error to TypeError (lib/fs.js) - update errors from ERR_INVALID_OPT_VALUE to ERR_INVALID_ARG_TYPE in the functions fs.ReadStream() and fs.WriteStream(), for the cases of range errors use the new error: ERR_VALUE_OUT_OF_RANGE (lib/fs.js) PR-URL: #15043 Refs: #11273 Reviewed-By: Refael Ackermann <refack@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Michael Dawson <michael_dawson@ca.ibm.com>
