/**
* \brief Check whether a buffer contains a valid and authentic record
* that has not been seen before. (DTLS only).
*
* This function does not change the user-visible state
* of the SSL context. Its sole purpose is to provide
* an indication of the legitimacy of an incoming record.
*
* This can be useful e.g. in distributed server environments
* using the DTLS Connection ID feature, in which connections
* might need to be passed between service instances on a change
* of peer address, but where such disruptive operations should
* only happen after the validity of incoming records has been
* confirmed.
*
* \param ssl The SSL context to use.
* \param buf The address of the buffer holding the record to be checked.
* This must be a read/write buffer of length \p buflen Bytes.
* \param buflen The length of \p buf in Bytes.
*
* \note This routine only checks whether the provided buffer begins
* with a valid and authentic record that has not been seen
* before, but does not check potential data following the
* initial record. In particular, it is possible to pass DTLS
* datagrams containing multiple records, in which case only
* the first record is checked.
*
* \note This function modifies the input buffer \p buf. If you need
* to preserve the original record, you have to maintain a copy.
*
* \return \c 0 if the record is valid and authentic and has not been
* seen before.
* \return MBEDTLS_ERR_SSL_INVALID_MAC if the check completed
* successfully but the record was found to be not authentic.
* \return MBEDTLS_ERR_SSL_INVALID_RECORD if the check completed
* successfully but the record was found to be invalid for
* a reason different from authenticity checking.
* \return MBEDTLS_ERR_SSL_UNEXPECTED_RECORD if the check completed
* successfully but the record was found to be unexpected
* in the state of the SSL context, including replayed records.
* \return Another negative error code on different kinds of failure.
* In this case, the SSL context becomes unusable and needs
* to be freed or reset before reuse.
