Hey all,
As the subject says, this set adds support for HDCP 1.4 over MST. Most
of the set is plumbing and refactor to allow the MST support to slot in
organically.

I stubbed out HDCP 2.2 support since I don't have a means of testing it.
If no one picks up the slack, I can come back to it at a later date when
I have the right gear.

Please take a look,

Sean
