This patch moves the displaystate callback calls for setting the cursor
and the mouse pointer from spice server to qemu (iothread) context.
This allows us to simplify locking.

This patch moves the creation of spice screen updates from the spice
server context to qemu iothread context (display refresh timer to be
exact). This way we avoid accessing qemu internals (display surface)
from spice thread context which in turn allows us to simplify locking.

qemu_spice_create_update() must aquire the global qemu mutex to
make sure DisplayState doesn't change while we are accessing it.
Once this is in place the private lock is pretty pointless as
everything it protects is covered by the global qemu mutex now.
Drop it.

With that patch applied you'll actually see the guests screen in the
spice client. This does *not* bring qxl and full spice support though.
This is basically the qxl vga mode made more generic, so it plays
together with any qemu-emulated gfx card. You can display stdvga or
cirrus via spice client. You can have both vnc and spice enabled and
clients connected at the same time.
