lguest: remove NOTIFY call and eventfd facility.
Disappointing, as this was kind of neat (especially getting to use RCU to manage the address -> eventfd mapping). But now the devices are PCI handled in userspace, we get rid of both the NOTIFY hypercall and the interface to connect an eventfd. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
