EDID 1.4 forbids years < 2006, but EDID 1.3 allows them.
Error out when an EDID uses a reserved value. Correctly parse the
year on older EDID revisions.

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].

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.

The analog/digital flags are left for a future patch.
A join_str() function is introduced in di-edid-decode: upstream
edid-decode uses a comma-separated list with a handful of other
flags.

This adds coverage for two untested code-paths:
- Unset "Serial Number"
- "Model year" instead of "Made in"
This EDID blob comes from Digital/Panasonic/MEI96A2/7CA47BE65E1E [1]
in the linuxhw EDID repository.

While this isn't particularly interesting to print, this reduces
the diff between di-edid-decode and edid-decode.
This is not exposed via the low-level EDID library because callers
wouldn't have a use for it.

It sounds like the CI container was shipping an outdated version
of edid-decode which doesn't match the commit recorded in
.gitlab-ci.yml.
Update the diffs in the test data, and bump the CI container tag
again to make sure it's up-to-date with the manifest.

Add two small shell utilities to generate and compare diffs between
edid-decode and di-edid-decode. Store the diffs in-tree and add tests
to ensure they don't regress. Run the tests in CI with a pinned
installation of edid-decode.
One EDID blob is added to the test collection: dell-2408wfp-dp. It's
extracted [1] from the edid-decode repository.
