We weren't properly iterating the extension blocks and thought we
encountered an unexpected extension map block, when we really should
have just skipped over it.
This downloads the UEFI's published PNP ID database and generates a
lookup table for use in LibEDID. The lookup table isn't optimized at
all, but this can be easily done at a later point if needed.
This library can be used (for the most part) by kernel drivers as well
as user mode. For this reason FixedPoint is used rather than floating
point, but kept to a minimum.
