 *  Fix: Don't reuse connections after an unsuccessful `Expect: 100-continue`.
 *  Fix: Handle either `TLS_` or `SSL_` prefixes for cipher suite names. This is necessary for
    IBM JVMs that use the `SSL_` prefix exclusively.
 *  Fix: Reject HTTP/2 data frames if the stream ID is 0.
 *  New: Upgrade to Okio 1.12.0.
