This function will set the maximum size of the *unencrypted*
records which will be sent over a DTLS session. It is
equivalent to calculating the DTLS packet overhead with the
current encryption parameters, and calling
gnutls_dtls_set_mtu() with that value. In particular, this
means that you may need to call this function again after
any negotiation or renegotiation, in order to ensure that
the MTU is still sufficient to account for the new protocol

In most cases you only need to call gnutls_dtls_set_mtu()
with the maximum MTU of your transport layer.
