Improve sequence and sense of messages from pg_stop_backup(). Now doesn't report it is waiting until it actually is waiting, plus message doesn't appear until at least 5 seconds wait, so we avoid reporting the wait before we've given the archiver a reasonable time to wake up and archive the file we just created earlier in the function. Also add new unconditional message to confirm safe completion. Now a normal, healthy execution does not report waiting at all, just safe completion.
