Merge branch 'nick/ssh/sign-verify-binary' into maint-r14
* nick/ssh/sign-verify-binary: Updated appup file. Updated notes file. Changed year in copyright header. Added updated modules to the appup file. Improved error handling for ssh:connect/3/4. Release note contained wrong ticker number. OTP-8987 In some cases SSH returned {error, normal} when a channel was terminated unexpectedly. This has now been changed to {error, channel_closed}.
