and packet_read may return SSH_AGAIN if the session is nonblocking and
there is not enough data to be read.
I also added a socket buffering through session->in_socket_buffer. It is
more low-level than the packet buffer.
I should rename in_buffer with in_packet_buffer.
There is still work to do with the socket status, (opened, error,
closed, ...) and much more work to extend the nonblocking to session
opening, messages sending and such.
I find the switch(session->packet_state) solution very nice (especially
when the nonblocking function may have 10 differents states, like in a
connection.)
