Detailed Description

Finds out which of the devices yaacc knows speak the protocol, once per device: the description is fetched, the control interface is looked for (YxcDescriptionParser), and the answer is remembered per UDN, including "this is not such a device".

A device that did not answer is asked again after RETRY_AFTER_MILLIS. A device whose description URL changed (new address) is looked at again.

The address of the endpoint is the one of the description URL that yaacc's own registry gave; the host a document names is used only to take over its port when it names the same host, so a device can not send yaacc elsewhere.
