Fixes#2101. There are 3 related changes made here:
1. Move the SWIG_globals() singleton into pyrun from pyint so it
is visible to SWIG_Python_DestroyModule(). The static globals
varlink has been extracted out of the function so that it can
be set to NULL in SWIG_Python_DestroyModule(), which fixes the
issue described in #2101. (Now when the second interpreter
starts up, the Swig_Globals_global pointer will be NULL, so it
knows it has to create a new one.)
2. Remove a Py_DECREF on the globals varlink. The decrement is now
performed by DestroyModule(), so there's no need to do it in
SWIG_init().
3. Fixed similar issue with SWIG_Python_TypeCache().

This directory contains all of the SWIG language modules. Many of these
modules contain code that dates back to SWIG1.0. The module API has changed
a lot in the development releases so this is fairly messy. We're working on
cleaning it up, but you'll have to bear with us until it's done.
