This is the "original" code previously used to generate a GENMIDI
lump, and the original set of patches.

This code generates a functional GENMIDI lump using the free patch data
from the OpenBSD OPL MIDI driver. The result doesn't sound quite as
good as the original Doom lump; however, most source ports don't use
GENMIDI anyway nowadays, so this should be good enough.
