First attempt on making display updates thread-save for real.  Most
interesting patches at this point are #2 (adds helper functions to
create and use a dirty bitmap copy) and #3 (updates vga code to use

Patch #1 fixes a bug I've noticed while wading through the vga code,
and #4 removes the temporary workaround for testing purposes.  Which
will of course break some or all non-vga display adapters as those
are not ported over yet.

git branch is available here:
  git://git.kraxel.org/qemu work/vga-fixes

Gerd Hoffmann (4):
  vga: add vga_scanline_invalidated helper
  memory: add support getting and using a dirty bitmap copy.
  vga: make display updates thread safe.
  [testing] console: remove do_safe_dpy_refresh
