ssdp_poll: reimplement for taxonomy as ssdptax.
SSDP can provide much better information about devices
than we currently use it for. Now that catawampus no
longer uses ssdp_poll, turn it into a source of taxonomy
information for client devices.
Rename it as 'ssdptax' to reflect its new purpose.
Also:
+ add an opensource copyright header, we
neglected to do that when this file was first
released (in 2014).
+ be more cautious about the strings returned
from SSDP. Only allow alphanumerics & space,
turn everything else into an underscore.
