a fake `HostnameVerifier` or `X509TrustManager`.

Certificate Authorities
-----------------------

The above example uses a self-signed certificate. This is convenient for testing but not
representative of real-world HTTPS deployment. To get closer to that we can use `HeldCertificate`
to generate a trusted root certificate, an intermediate certificate, and a server certificate.

    val writer = Http2Writer(Buffer(), true)
    assertFailsWith<IllegalArgumentException> {
      writer.frameHeader(0, 16777216, Http2.TYPE_DATA, FLAG_NONE)
    }.also { expected ->
      // TODO: real max is based on settings between 16384 and 16777215
      assertThat(expected.message).isEqualTo("FRAME_SIZE_ERROR length > 16384: 16777216")
    }
  }
