Bug in Python string conversion

Both Python strings and 'std::string' support embedded '\0' characters.
However, 'boost::python::from_python(PyObject *,
boost::python::type<std::string>' fails to correctly convert Python strings
with embedded '\0' to 'std::string'.  I propose the following alternate
implementation:

std::string from_python(PyObject *p, boost::python::type<std::string>)
{
  int length;
  char *s;
  if (PyString_AsStringAndSize(p, &s, &length))
    throw boost::python::argument_error();
  return std::string(s, length);
}

There is a similar problem in 'boost::python::to_python(const
std::string&)'.  I propose the following alternate implementation:

PyObject *to_python(const std::string& s)
{
  return PyString_FromStringAndSize(s.data(), s.size());
}
