epoller

epoll implementation for connections in Linux, MacOS and windows.

Its target is implementing a simple epoll for connection, so you should see it only contains few methods:

type Poller interface {
    Add(conn net.Conn) error
    Remove(conn net.Conn) error
    Wait(count int) ([]net.Conn, error)
    WaitWithBuffer() ([]net.Conn, error)
    WaitChan(count int) <-chan []net.Conn
    Close() error
}

Welcome any PRs for windows IOCompletePort.

Inspired by 1m-go-websockets.

Thanks @sunnyboy00 for providing windows implementation.
