04d86aeeae channels: Implement better ssh_channel_get_exit_state() variant
This way we will get errors as return code else we don't know if the
function failed (SSH_ERROR) or the exit_status is -1 which would
correspond to SSH_ERROR.

e0985fc0b4 client: Add ssh_session_set_disconnect_message()
Fix #98 by adding 'ssh_session_set_disconnect_message' Whenever the ssh
session disconnects a "Bye Bye" message was set and displayed. Now the
peer has a choice to set a customised message to be sent after the
session is disconnected. The default "Bye Bye" will be set if this
function is not called or not called correctly. The testcases in
tests/server/torture_server can also demonstrate how this function
works.

51a53cc6d4 add support for identityagent ssh_config option
This commit adds an `agent_socket` field to the session options
and connects the config parser to that option.

`SSH_OPTIONS_IDENTITY_AGENT` is added to allow applications to
set this option for themselves.

agent.c is updated to take the `agent_socket` value in preference
to the `SSH_AUTH_SOCK` environment variable.
