/**
* \brief Update record layer
*
* This function roughly separates the implementation
* of the logic of (D)TLS from the implementation
* of the secure transport.
*
* \param ssl The SSL context to use.
* \param update_hs_digest This indicates if the handshake digest
* should be automatically updated in case
* a handshake message is found.
*
* \return 0 or non-zero error code.
*
* \note A clarification on what is called 'record layer' here
* is in order, as many sensible definitions are possible:
*
* The record layer takes as input an untrusted underlying
* transport (stream or datagram) and transforms it into
* a serially multiplexed, secure transport, which
* conceptually provides the following:
*
* (1) Three datagram based, content-agnostic transports
* for handshake, alert and CCS messages.
* (2) One stream- or datagram-based transport
* for application data.
* (3) Functionality for changing the underlying transform
* securing the contents.
*
* The interface to this functionality is given as follows:
*
* a Updating
* [Currently implemented by mbedtls_ssl_read_record]
*
* Check if and on which of the four 'ports' data is pending:
* Nothing, a controlling datagram of type (1), or application
* data (2). In any case data is present, internal buffers
* provide access to the data for the user to process it.
* Consumption of type (1) datagrams is done automatically
* on the next update, invalidating that the internal buffers
* for previous datagrams, while consumption of application
* data (2) is user-controlled.
*
* b Reading of application data
* [Currently manual adaption of ssl->in_offt pointer]
*
* As mentioned in the last paragraph, consumption of data
* is different from the automatic consumption of control
* datagrams (1) because application data is treated as a stream.
*
* c Tracking availability of application data
* [Currently manually through decreasing ssl->in_msglen]
*
* For efficiency and to retain datagram semantics for
* application data in case of DTLS, the record layer
* provides functionality for checking how much application
* data is still available in the internal buffer.
*
* d Changing the transformation securing the communication.
*
* Given an opaque implementation of the record layer in the
* above sense, it should be possible to implement the logic
* of (D)TLS on top of it without the need to know anything
* about the record layer's internals. This is done e.g.
* in all the handshake handling functions, and in the
* application data reading function mbedtls_ssl_read.
*
* \note The above tries to give a conceptual picture of the
* record layer, but the current implementation deviates
* from it in some places. For example, our implementation of
* the update functionality through mbedtls_ssl_read_record
* discards datagrams depending on the current state, which
* wouldn't fall under the record layer's responsibility
* following the above definition.
*
