fixes #393 panic on illumos - epoll assertion error

This replaces the epoll support with proper illumos/SunOS port
events.  The port event support is structured so that it actually
is superior to epoll and kqueue, because it avoids a single master
lock on the poller.  In the future we will explore this for macOS
and Linux pollers.
