Summary: Expose _Py_ReleaseInternedStrings

Initial Comment:
An implementation of the idea expressed here:

http://mail.python.org/pipermail/python-dev/2002-June/025067.html

This exposes the clearing of the intern dictionary to
Python via gc.release_interns().  Patch includes doc
updates and a test case.

Guido also suggests to move this sys instead of gc (although
gc isn't totally out of the question).  Maybe Neil has an
opinion one way or the other?

Yes, I know why this isn't right.  Notes:

- we probably want to incref the string pointed to by
ob_intern so that the reference is counted in the interned
string's refcount

- when the referent is freed, we'll need to decref the ob_intern

this addresses

Um, that's totally unsafe. See
