Eric Garrido 83f1503f77 crypto/ssh: Handle error in dial to avoid a goroutine leak 
If the channel open request failed, a nil channel would be provided to
DiscardRequests, which would never return.

We return the error early to avoid this goroutine leak.

Jakob Borg 4758fe8ce4 go.crypto/ssh: Increase window size. 
Increase window size for channels (session and tcpip) to 64 *
max packet size (32 KB), which is the same value that OpenSSH
uses. Also breaks out the relevant harcoded constants into named
constants in channel.go.

Fixes golang/go#6675.

Dave Cheney c0d640c887 go.crypto/ssh: ensure {Server,Client}Conn do not expose io.ReadWriter 
Transport should not be a ReadWriter. It can only write packets, i.e. no partial reads or writes. Furthermore, you can currently do ClientConn.Write() while the connection is live, which sends raw bytes over the connection. Doing so will confuse the transports because the data is not encrypted.

As a consequence, ClientConn and ServerConn stop being a net.Conn

Finally, ensure that {Server,Client}Conn implement LocalAddr and RemoteAddr methods that previously were exposed by an embedded net.Conn field.
