This function will register a new extension type. The extension will remain registered until gnutls_global_deinit() is called. If the extension type is already registered then GNUTLS_E_ALREADY_REGISTERED will be returned. Each registered extension can store temporary data into the gnutls_session_t structure using gnutls_ext_set_data(), and they can be retrieved using gnutls_ext_get_data(). Any extensions registered with this function are valid for the client and TLS1.2 server hello (or encrypted extensions for TLS1.3). This function is not thread safe.
