fuzz-socks5 drives socks5_handshake_scripted() with a hostile proxy reply. The input carries the origin address and the proxy URL on its first two lines, so the port parser and the RFC 1929 credential decoder run too. The harness aborts if the reader consumes past the script, or if a handshake reported as successful did not end with a whole CONNECT frame.

fuzz-socks5, which runs the SOCKS5 client handshake against a hostile proxy reply throughsocks5_handshake_scripted(). Its input also carries the origin address and the proxy URL, so the port parser and the proxy credential decoder are fuzzed too.
