lguest: allow any process to send interrupts
We currently only allow the Launcher process to send interrupts, but it as we already send interrupts from the hrtimer, it's a simple matter of extracting that code into a common set_interrupt routine. As we switch to a thread per virtqueue, this avoids a bottleneck through the main Launcher process. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
