+bits shared by the bytesobject and unicodeobject implementations (and
+possibly other modules, in a not too distant future).
+
+the stuff in here is included into relevant places; see the individual
+source files for details.
+
+--------------------------------------------------------------------
+the following defines used by the different modules:
+
+STRINGLIB_CHAR
+
+ the type used to hold a character (char or Py_UNICODE)
+
+STRINGLIB_GET_EMPTY()
+
+ returns a PyObject representing the empty string, only to be used if
+ STRINGLIB_MUTABLE is 0. It must not be NULL.
+
+Py_ssize_t STRINGLIB_LEN(PyObject*)
+
+ returns the length of the given string object (which must be of the
+ right type)
+
+PyObject* STRINGLIB_NEW(STRINGLIB_CHAR*, Py_ssize_t)
+
+ creates a new string object
+
+STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)
+
+ returns the pointer to the character data for the given string
+ object (which must be of the right type)
+
+int STRINGLIB_CHECK_EXACT(PyObject *)
+
+ returns true if the object is an instance of our type, not a subclass
+
+STRINGLIB_MUTABLE
+
+ must be 0 or 1 to tell the cpp macros in stringlib code if the object
+ being operated on is mutable or not
