The repeated calls to WaitForMultipleObjects may cause a livelock in aio_poll,
where no progress is made on bottom halves. This patch matches the behavior
of the POSIX code.

In the current code, this is done by qemu_set_fd_handler2, which is
called by qemu_aio_set_fd_handler. We need to keep the same behavior
even after removing the call to qemu_set_fd_handler2.

This lets AioContexts be used (optionally) with a glib main loop.

The Win32 implementation will only accept EventNotifiers, thus a few
drivers are disabled under Windows. EventNotifiers are a good match
for the GSource implementation, too, because the Win32 port of glib
allows to place their HANDLEs in a GPollFD.
