be22c0d442 Add a NODELAY option 
Add a new option SSH_OPTIONS_NODELAY to enable or disable the
Nagle Algorithm (TCP_NODELAY) on the session socket.

Improved performance can be achieved for some applications like
sftp servers by enabling SSH_OPTIONS_NODELAY as typically, the
next request won't arrive until the server replies, which are
typically small writes.

85ab4ee53a connector: ensure channel callbacks are removed 
ssh_connector_free fails to remove the in/out channel callbacks
as ssh_connector_remove_event sets the in/out channel variables
to NULL.

invoking ssh_connector_remove_event.

25f31760aa connector: Check for POLLHUP on in_fd 
POLLHUP needs to be checked on in_fd, which may be a pipe.
A pipe in Linux signals EOF through POLLHUP (see:
http://www.greenend.org.uk/rjk/tech/poll.html)

Without checking POLLHUP, a client could spin up indefinetely
doing ssh_event_dopoll.
