* \def MBEDTLS_SSL_CONTEXT_SERIALIZATION
*
* Enable serialization of the TLS context structures, through use of the
* functions mbedtls_ssl_context_save() and mbedtls_ssl_context_load().
*
* This pair of functions allows one side of a connection to serialize the
* context associated with the connection, then free or re-use that context
* while the serialized state is persisted elsewhere, and finally deserialize
* that state to a live context for resuming read/write operations on the
* connection. From a protocol perspective, the state of the connection is
* unaffected, in particular this is entirely transparent to the peer.
*
* Note: this is distinct from TLS session resumption, which is part of the
* protocol and fully visible by the peer. TLS session resumption enables
* establishing new connections associated to a saved session with shorter,
* lighter handshakes, while context serialization is a local optimization in
* handling a single, potentially long-lived connection.
*
* Enabling these APIs makes some SSL structures larger, as 64 extra bytes are
* saved after the handshake to allow for more efficient serialization, so if
* you don't need this feature you'll save RAM by disabling it.
*
* Comment to disable the context serialization APIs.
