Make this static method in ConnectionToHost?

I'm wondering if this should be in connection_to_host.h (I don't think the impl
headers should be included by anything other than the impl.cc file.  Can you
check with sergey and confirm?

Yeah, I don't think it belongs in this file. Move to
remoting/protocol/error.[h|cc]?

I've added an Error class which also has a static method.
