  Rework XPath rounding functions
  
  Use the C library's floor and ceil functions. The old code was overly
  complicated for no apparent reason and could result in undefined
  behavior when handling NaNs (found with afl-fuzz and UBSan).
  
  Fix wrong comment in xmlXPathRoundFunction. The implementation was
  already following the spec and rounding half up.
