ShouldSendRecieveHTTPS1 replays the plaintext round-trip over TLS, so a
regression in the transport shows up as an HTTP failure rather than
nothing at all, and adds what only exists under TLS: ALPN, scheme=https
reaching handlers, a body spanning many records, and the two ways
verification must fail — an untrusted self-signed certificate, and a
trusted certificate presented for the wrong name. A plaintext peer
knocking on the TLS port is asserted to be counted and shrugged off.
ShouldInteropCurlHTTPS1 puts real implementations on the other end, since
two OpenSSL peers can agree on a mistake. curl verifies our certificate
with --cacert rather than --insecure, and an h2-only curl is asserted to
be refused rather than mis-served. python3's http.server behind
ssl.wrap_socket answers HTTP/1.0 with Connection: close, which frames the
body by close_notify — the path a reader is most likely to get wrong.
ShouldRequireClientCertificateHTTPS1 covers mutual TLS both ways, and
drives TLSStream directly with hand-written HTTP/1.1 to keep the :TLS
layer honest as something usable without :ClientHTTP1 on top.
Also fix a delegation that `{}` no longer disambiguates now that a
three-argument TLS constructor exists alongside the fallback one.
