A socket layer that transforms between line endings.
When sending, LF not preceeded by CR is converted into CRLF. Stray CRs are kept. When receiving, CRs followed by LF are removed. As with sending, stray CRs ar kept.

overridevirtual |
Signals peers that we want to close the connections.
Only disallows further sends, does not affect reading from the socket.
Returns 0 on success, an error code otherwise. If it returns EGAIN, shutdown is not yet complete. Call shutdown again after the next write event.
Reimplemented from socket_layer.
