  Removed calls to PyFloat_AsReprString.
  This is in anticipation of possibly implementing issue 7117 (short float repr).
  This removes the last calls to PyFloat_AsString, PyFloat_AsReprString, and
  PyFloat_AsStringEx, which are unsafe.

  Also, switch to defines for error values to bring this code more in line
  with the py3k branch.
