Add ssh_get_poll_flags()

Browse Source 
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().
