title: c libs to have absolute file path which does not have /./ or /../ components
body: <p>I would like to remove all "./", or "../" from a input file path string.
  I know that "realpath" removes NOT only "./", or "../" BUT also symbolic link.</p>
  
  <p>Is there a library to remove all "./", or "../" from a input file path string and return the path without "./", or "../"?
