don't negotiate the idle timeout

Browse Source 
The idle timeout doesn't need to be negotiated, simply announcing it to
the peer is sufficient. We now close the session if there's no incoming
network activity for the duration of the local idle timeout, and we
send a PING frame after half the remote idle timeout (if keep alives are
enabled).
