* make errorx classifier less dependent on strings * adapt errorx tests * added syserror comment * localized classification of quic errors * localized classification of resolver errors * (fix) move "no such host" error to global classifier * moved x509 errors to local TLS error classifier * added qtls error classification for quicdialer * add Classifier to SafeErrWrapperBuilder * windows/unix specific files for errno constants * added errno ETIMEDOUT, tests * added TLS alert constants * added FailureSSLHandshake test, improved switch style * added more network based system error constants for future use * (fix) import style * (fix) errorx typos/style * (fix) robustness of SafeErrWrapperBuilder, added comments * (fix) reversed unnecessary changes, added comments * (fix) style and updated comment * errorx: added future re-structuring comment * (fix) typo TLS alert code 51 * added comment * alert mapping: added comment * Update errorx.go * Update internal/engine/netx/errorx/errorx.go Co-authored-by: Simone Basso <bassosimone@gmail.com>
