exp/terminal: split terminal handling from exp/ssh
This change splits terminal handling from exp/ssh, as suggested several times in the ssh code review. shell.go and shell_test.go are copies from exp/ssh with minimal changes, so don't need another full review. A future CL will remove that code from exp/ssh. R=bradfitz, r, dave, rsc CC=golang-dev https://golang.org/cl/5278049
