After all the discussions, I guess "CONN" for connection is the best way
to represent it.
I agree, after all in the latest proposal, the entity is really a connection
(or set of connections as for example in a S-Video with separate Y and C)
and the pads are the ones modeling the carrying signals.
Just some small typos mentioned below.
Better to put it on a patch.
Please review.

[media] Better define MEDIA_ENT_F_CONN_* entities
Putting concepts in a paper is hard, specially since different people
may interpret it in a different way.
Make clear about the meaning of the MEDIA_ENT_F_CONN_* entities
