Idea: move logic from src/unix/linux-core.c to src/unix/epoll.c and share that between Linux and Illumos.

Motivation:

• removes 250-300 lines of code from src/unix/sunos.c

• makes libuv more efficient because it no longer has to accommodate this event ports quirk:

diff --git a/src/unix/core.c b/s
