console/win32: allocate shareable display surface
Introduce qemu_win32_map_alloc() and qemu_win32_map_free() to allocate
shared memory mapping. The handle can be used to share the mapping with
another process.
Teach qemu_create_displaysurface() to allocate shared memory. Following
patches will introduce other places for shared memory allocation.
Other patches for -display dbus will share the memory when possible with
the client, to avoid expensive memory copy between the processes.
