- Enables channel_request_open types of DIRECT_TCPIP, FORWARDED_TCPIP and X11 (ie. implemented the handling of those channel_request_open types).
- Adds functions to retrieve the extra information relating to channel_request_open messages and channel_request messages.
- Adds a channel_write_stderr method (obviously for writing to the STDERR channel from server side) - well, technically just converted the exiting channel_write to take an extra argument and created two wrapper functions.
- Actually does the invoking of message_handle() from channel_recv_request.
- Implemented the handling of the window-change and env channel_requests.
- Implemented a few functions in server.h that were declared but not defined (eg. ssh_message_channel_request_channel).
