* more flexible render_webxdc_status_update_object() * delay webxdc updates when ratelimit is reached * inject updates messages to the SMTP loop as needed this avoids starting several tasks and allows sending updates out after a restart of the app. * use mutex to prevent race conditions in status updates * check ratelimiter only before the sending loop; it won't change until messages are actually sent out * fix typo * prefer standard type declaration over turbofish syntax * use UNIQUE and ON CONFLICT for query smtp_status_updates * combine DELETE+SELECT to one atomic statement * as all operations on smtp_status_updates are now atomic, a mutex is no longer needed * test DELETE+RETURNING statement * simplify calls to can_send() * comment about ratelimit boolean in send_smtp_messages()
