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.
