FYI, after adding qcodes to the keycodemapdb, (but not having picked
your branch), I see 131 keys where there is a known AT set 1 scancode,
but no corresponding QKeyCode.
I'll happily add the rest of them if you want (attaching the list)

I was actually just going add an entry for QKeyCode names to the
keycodemapdb, so we can convert straight to that, and also let
us auto-generate the qemu_input_linux_to_qcode() table.
Strangely there is no Linux key code defined for AltGr, so if we
map via Linux key codes, we would loose ability to send AltGr
