* mbedtls_ssl_conf_truncated_hmac() now returns void.
* mbedtls_memory_bufer_alloc_init() now returns void.
* X.509 verification flags are now an uint32_t. Affect the signature of:
mbedtls_ssl_get_verify_result()
mbedtls_x509_ctr_verify_info()
mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be update)
mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
* In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
return void.
* ecdsa_write_signature() gained an addtional md_alg argument and
