Summary: Modifying type.__module__ behavior

Initial Comment:
A __module__ attribute request on a C type will return
__builtin__ if the typeobject.c code cannot find a
period in the type name.  This is always incorrect for
extension libraries, and can be a _very_ confusing
error when trying to pickle your types (as the error
makes it seem as if you're supposed to register your
type in __builtin__).  I propose that:

A) All builtin Python types have a "__builtin__."
prefixed to their type declaration's name.

B) If the __module__ code cannot find a period, it
raises AttributeError with a somewhat descriptive
message.  This would be in the place where it returns
__builtin__.

C) The tp_name comment in Include/object.h describe the
special semantics.  "/* 'module.typename' */", for example.

This is a lot of files to change, I know, but it's only
one or two line changes each file.  The only code this
should affect is code which is written incorrectly; it
may not understand the name semantics, or it may
actually be registering itself in __builtin__ (as I did
before I figured out what it was doing).  Otherwise
we're golden.
