    The SSLTransport wraps an existing socket and establishes an SSL connection.

    Contrary to Python's implementation of SSLSocket, it allows you to chain
    multiple TLS connections together. It's particularly useful if you need to
    implement TLS within TLS.

    The class supports most of the socket API operations.

        Raises a ProxySchemeUnsupported if the provided ssl_context can't be used
        for TLS in TLS.

        The only requirement is that the ssl_context provides the 'wrap_bio'
        methods.

        Python's httpclient uses makefile and buffered io when reading HTTP
        messages and we need to support it.

        This is unfortunately a copy and paste of socket.py makefile with small
        changes to point to the socket directly.
