Mirror upstream edid-decode.

samsung-s27a950d-dp and hp-5dq99aa-hdmi are missing some failures
about features we haven't implemented yet. panasonic-mei96a2-dp
has a bogus "Missing Display Product Name" failure, see [1].

4f4aa025cf edid: add display range limits type
This is a bit messy because the values depend on various misc flags
defined earlier in the spec, and the meaning changes between EDID 1.3
and 1.4. On top of that edid-decode prints something confusing in the
EDID 1.3 case.
