ac857e8985 info: use PNP ID database for manufacturer names
The three character PNP ID is a key to manufacturer name database. It
may be desirable to report the manufacturer's real name than just PNP ID
which can be misleading, e.g. MSI refers to Microstep and not MSI GmbH.

This builds the PNP ID database into libdisplay-info to avoid having to
find and parse files at runtime.

tool/gen-search-table.py started as a copy of Wayland 1.21.0's
src/embed.py and took influence from
10945c4ed8/conv.py
However, our script parses the text file shipped in hwdata package in
Debian (and presumably other distributions) rather than the original
CSV.

f70fa58441 test: add high-level API test
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.

c930f13457 test: add custom-uncommon-cta-vesa
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.

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.
