There are plenty of ways attaching can go wrong. Having the server report the exact error means we can give better feedback to the user. (This patch does not do the second part, it only makes sure the information is sent from the server.) Triggering all possible error conditions in a test would prove challenging, but there is one error that is very easy to reproduce (attempting to attach while debugging), so I write a test based on that. The test immediately exposed a bug where the m_send_error_strings field was being used uninitialized (so it was sometimes true from the get-go), so I fix that as well. llvm-svn: 329803
