On the client side, it is never necessary to call this method;
although the connection needs to perform a handshake after
connecting (or after sending a "STARTTLS"-type command) and may
need to rehandshake later if the server requests it,
#GDtlsConnection will handle this for you automatically when you try
to send or receive data on the connection. However, you can call
g_dtls_connection_handshake() manually if you want to know for sure
whether the initial handshake succeeded or failed (as opposed to
just immediately trying to write to @conn, in which
case if it fails, it may not be possible to tell if it failed
before or after completing the handshake).
Likewise, on the server side, although a handshake is necessary at
the beginning of the communication, you do not need to call this
function explicitly unless you want clearer error reporting.
However, you may call g_dtls_connection_handshake() later on to
renegotiate parameters (encryption methods, etc) with the client.
#GDtlsConnection::accept_certificate may be emitted during the
handshake.
Attempts a TLS handshake on @conn.
