Peter Moody e84a34b1ee x/crypto/ssh: support more keytypes in the agent. 
This allows the golang ssh-agent to support the full suite of keys
the library accepts.

Currently constraints are ignored.

Dave Cheney 36d74d6fed go.crypto/ssh: fix panic unmarshalling channelOpenFailureMsg 
I introduced this problem in change set 33 when I redefined
RejectionReason from a uint32 to an int. I have added a test
to verify the message can be marshaled correctly.

This was a bit hard to track down as the recover in clientConn
mainLoop would catch the panic and shutdown the connection. We
probably shouldn't be using panic inside marshal/unmarshal, at
least not without a way to let the user know why the recover
logic tripped.
