Daniel J. Hofmann 7f71f0ed12 Warn on unused return values in guidance code, resolves #2686.
https://github.com/Project-OSRM/osrm-backend/pull/2685/files

fixes an issue where we did

    elongate(fstStep, sndStep);

instead of

    newStep = elongate(fstStep, sndStep);

we didn't get any warnings.

The only way to trigger a warning here is to use

```cpp
__attribute__((warn_unused_result))
```

This changeset does exactly that: for the new guidance code prone to
these kind of issue we add such an attribute to the declaration.
