I forgot to note, the Wayland protocol implementation would be in
Weston upstream. There should be no reason to push that out to an
external plugin. So Weston upstream would not only offer
set_srm_table() but also take care of tracking the protection status,
enabling HDCP on Wayland client request and reporting the status to the
client.

It is only the SRM table management that I am concerned about. And the
topology thing, but I know nothing about that yet.
