Paolo Bonzini 19d2b5e6ff i8257: rewrite DMA_schedule to avoid hooking into the CPU loop 
The i8257 DMA controller uses an idle bottom half, which by default
does not cause the main loop to exit.  Therefore, the DMA_schedule
function is there to ensure that the CPU relinquishes the iothread
mutex to the iothread.

However, this is not enough since the iothread will call
aio_compute_timeout() and go to sleep again.  In the iothread
world, forcing execution of the idle bottom half is much simpler,
and only requires a call to qemu_notify_event().  Do it, removing
the need for the "cpu_request_exit" pseudo-irq.  The next patch
will remove it.
