Thiago de Arruda 6493ffac1f contrib/ycm_extra_conf.py (#6257)
- Remove some unnecessary code: IsHeaderFile is no longer required, as the logic
  to find flags to headers is now built into YCM
- Add function to make paths in flags absolute: It seems YCM is not correctly
  resolving paths in flags to consider `build` as the compiler working
  directory.
- Update documentation.
