[SeaBIOS] seabios release planning

/me got sick, so with the xmas/newyear holidays being just around the
corner that implies I'll be offline for the rest of the year.

Kevin will most likely tag v1.7.4 nevertheless, but updating the qemu
tree will be delayed until january.

Anyone being hit by seavgabios breaking windows guests can either apply
this patch as workaround ...

... or just update the seabios submodule to v1.7.4, the rebuild both
bios and vgabios ("make bios; make seavgabios" in roms/).

happy xmas everyone,
  Gerd
