Add support for VHOST_USER_PROTOCOL_F_IN_BAND_NOTIFICATIONS, but as it's not desired by default, don't enable it unless the device implementation opts in by returning it from its protocol features callback. Note that I updated vu_set_vring_err_exec(), but didn't add any sending of the VHOST_USER_SLAVE_VRING_ERR message as there's no write to the err_fd today either. This also adds vu_queue_notify_sync() which can be used to force a synchronous notification if inband notifications are supported. Previously, I had left out the slave->master direction handling of F_REPLY_ACK, this now adds some code to support it as well.
