Improve interoperability with SSH clients
This patch fixes a few problems of the SSH shell server that affect the
interoperability with SSH clients in widespread use.
First problem is that, whenever a channel_request message is
received with want_reply=true, the reply ends up being sent to the
servers channel id, not the clients channel id. This causes the client
to terminate the connection. The easiest solution to the problem appears
to be a new function in ssh_connection_manager.erl that translates the
servers channel id before sending the reply (in the same manner as
other functions do it).
Second problem is in ssh_cli.erl. When an SSH client sends a
window_change request between PTY allocation and starting the shell
(which appears to happen with some clients), ssh_cli.erl crashes
because #state.buf is yet 'undefined'. Allocating an empty buffer at PTY
allocation time solves the problem.
Affected SSH clients:
- all clients based on SSH-2.0-TrileadSSH2Java_213 (problem #1)
- SSH Term Pro (problem #2)
