lguest: turn Waker into a thread, not a process
lguest uses a Waker process to break it out of the kernel (ie.
actually running the guest) when file descriptor needs attention.
Changing this from a process to a thread somewhat simplifies things:
it can directly access the fd_set of things to watch. More
importantly, it means that the Waker can see Guest memory correctly,
so /dev/vring file descriptors will work as anticipated (the
alternative is to actually mmap MAP_SHARED, but you can't do that with
/dev/zero).
