Hmm, we recently split out the keymap database and code for generating
lookup tables (that was duplicated across spice-gtk, gtk-vnc, and libvirt)
into a shared git sub-module

  https://gitlab.com/keycodemap/keycodemapdb/

some other VNC clients were also switching to its use.

I was coincidentally working on a patch to get QEMU to use this too,
so all projects are aligned on the same data maps and thus share fixes
in this area.

IMHO that'd be preferable than doing something custom in QEMU only.
