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.

b3231b85dd info: add getters for make, model and serial
The functionality of these new high-level functions as implemented here
follows what Weston 11.0's ad hoc EDID parser extracted. There are
differences to Weston though:
- get_model() falls back to the numeric model field
- unusual characters are escaped as hex rather than replaced with dash

The documentation of the new functions allows to change the behavior of
get_model and get_make to e.g. convert PNP ID to a company name. The
notes about UTF-8 allow us to make use of UTF-8 fields if such appear
useful in the future.

Weston's ad hoc parser shall be replaced with this. After another API
addition, the high-level API semantics will match what Weston expects.

The memory_stream stuff is for convenience and will see more complex
use in the future.

add5d0bd76 info: drop di_info_get_product_name()
This was used as an example of what a high-level API function would
look like, but is too opinionated to be useful across many
compositors.

c383417629 edid: prefix private functions with "_di_"
The extra underscore indicates that it's not a function which is
part of our public API. This will allow the next commit to setup the
linker to export functions based on their name.

321d5dbcba Add di_info_get_product_name
This high-level function leverages the low-level
di_edid_get_vendor_product function to build a string describing
the display device product.

c01982bdb1 Add skeleton for high-level API
This exposes a new di_info opaque struct from which high-level
information will be able to be queried by the user. A new
di_info_parse_edid function creates a di_info from an EDID blob.
