kill dead code that annoys sonar

kill dead code that annoys sonar

- I guess that these names were intended to help debugging
- but there is no way it can be directly used, as we are filling
  strings where surf usually provides resources. So, nothing of the
  logging or whatsoever can use them.
- Sonar don't like them because we have to cast the constness
- so wipe that out and forget about this file for now.
