* \def MBEDTLS_ECP_RESTARTABLE
*
* Enable "non-blocking" ECC operations that can return early and be resumed.
*
* This allows various functions to pause by returning
* #MBEDTLS_ERR_ECP_IN_PROGRESS (or, for functions in the SSL module,
* #MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS) and then be called later again in
* order to further progress and eventually complete their operation. This is
* controlled through mbedtls_ecp_set_max_ops() which limits the maximum
* number of ECC operations a function may perform before pausing; see
* mbedtls_ecp_set_max_ops() for more information.
*
* This is useful in non-threaded environments if you want to avoid blocking
* for too long on ECC (and, hence, X.509 or SSL/TLS) operations.
*
* This option:
* - Adds xxx_restartable() variants of existing operations in the
* following modules, with corresponding restart context types:
* - ECP (for Short Weierstrass curves only): scalar multiplication (mul),
* linear combination (muladd);
* - ECDSA: signature generation & verification;
* - PK: signature generation & verification;
* - X509: certificate chain verification.
* - Adds mbedtls_ecdh_enable_restart() in the ECDH module.
* - Changes the behaviour of TLS 1.2 clients (not servers) when using the
* ECDHE-ECDSA key exchange (not other key exchanges) to make all ECC
* computations restartable:
* - ECDH operations from the key exchange, only for Short Weierstrass
* curves, only when MBEDTLS_USE_PSA_CRYPTO is not enabled.
* - verification of the server's key exchange signature;
* - verification of the server's certificate chain;
* - generation of the client's signature if client authentication is used,
* with an ECC key/certificate.
*
* \note In the cases above, the usual SSL/TLS functions, such as
* mbedtls_ssl_handshake(), can now return
* MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS.
*
* \note This option only works with the default software implementation of
* elliptic curve functionality. It is incompatible with
* MBEDTLS_ECP_ALT, MBEDTLS_ECDH_XXX_ALT, MBEDTLS_ECDSA_XXX_ALT.
*
* Requires: MBEDTLS_ECP_C

* \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.
*
* Requires: MBEDTLS_GCM_C or MBEDTLS_CCM_C or MBEDTLS_CHACHAPOLY_C
