runtime: network poller for freebsd/arm, netbsd/amd64,386,arm

[mikioh]

Splitted from issue #5199, focused on supporting runtime-integrated network pollster
FreeBSD/ARM and NetBSD/AMD64,386,ARM. Only thing we need to do here is adding kqueue,
kevent assembly fragments.

Comment 2:

How close are these? What can we do to get them in soon? It would be nice to have this
all settled by Sept 1. It looks like maybe NetBSD is just the system calls, so maybe
Minux can resend the CL? And is FreeBSD just the system calls too?
