* Add support for packing multiple records within a single datagram,
enabled by default.
* Add support for buffering out-of-order handshake messages.
* Add support for buffering out-of-order handshake messages in DTLS.
The maximum amount of RAM used for this can be controlled by the
compile-time constant MBEDTLS_SSL_DTLS_MAX_BUFFERING defined
in mbedtls/config.h.

* This should be at least 9/8 * MBEDTLSSL_IN_CONTENT_LEN

* A value of 2 * MBEDTLS_SSL_IN_CONTENT_LEN (32768 by default)
