Add ssh_get_poll_flags()
For integration with an external mainloop, we need to know how to replicate libssh's internal poll() calls. We originally through ssh_get_status() was that API, but it's not really - those flags only get updated from the *result* of a poll(), where what we really need is to know how libssh would *start* a poll().
