Keep looping over all channels until none return data.
The same thing can happen there. Even if no libssh2_channel_read_ex()
call returns data during a loop, one of them can read data from the
socket, for a channel which has already been checked. What I need is a
way to check for data *without* reading more from the socket.
I would probably have designed the API so that the app explicitly reads
socket data with libssh2_transport_read(), wrapped in
libssh2_session_read(), and libssh2_channel_read() would only operate on
that data, it wouldn't call libssh2_transport_read() itself. But I guess
it's too late to make such a change.
