by storing the reference edid-decode output in the repository. It is now
only a dependency for the gen-test-data target. The CI checks that the
reference output in the repository matches the one generated from a
specific checkout of edid-decode.

This makes it easier to re-generate the test diffs. The build system
will properly set DI_EDID_DECODE/DI_EDID_PRINT (and will rebuild
these tools if they are out-of-date).

This new test exercises all existing high-level API to make sure the
output does not change unexpectedly.
Unlike with edid-decode tests, these new print tests do not have an
externally defined groundtruth. They are only to detect changes and
exercise code paths.

This is a hand-crafted EDID taken from edid-decode (test/cta-vesa.test).
It contains uncommon blocks: VESA Display Transfer Characteristics Data
Block and VESA Video Display Device Data Block in the CTA-861 extension.
While it's not as good as a real-world EDID, it can still improve our
test coverage and ensure we behave like edid-decode.

This makes it easier to perform an operation on all EDID files at
once, e.g. "test/edid-decode-diff.sh test/data/*.edid" to update all
diffs at once.

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.

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.
