- Added --start option to mysqld which don't prints notes to log on startup
  This helps to find errors in configure options easier
- Dont write [Note] entries to log after we have abort the server
  This makes it easier to find what went wrong
- Don't by default write out Changed limits for max_open_files as this didn't really change from anything the user gave us
- Dont write warnings about not using --explicit_defaults_for_timestamp (we don't have plans do depricate the old behaviour)
