Add prototype for epoll() system call, defined in fs/eventpoll.c. This
interface behaves like kevent() in BSD systems in that it supports
the addition/deletion/modification of eventpoll entries in the same
system call that polls for ready events.

Reserve a small ioctl() command space for eventpolls, of which only two
