* config.c: Added audioop to lists.

gvanrossum · gvanrossum · commit c89705d6975f · 1992-11-26T08:54:07.000Z
* Makefile: change default source directory
* socketmodule.c: added getsockname and getpeername
* bltinmodule.c: corrected typo in type() error message
* Added new built-in functions str() and repr(): repr(x) == `x`;
  str(x) == x if x is a string, otherwise str(x) == repr(x).
* Added joinfields to stropmodule.c (string.join calls joinfields now)
