normalize exceptions passed to the __exit__ method #7853
In Python 2.x, exceptions in finally blocks are not normalized. Since with
statements are implemented using finally blocks, ceval.c had to be tweaked to
distinguish between with finally blocks and normal ones.
A test for the finalization of generators containing with statements was also
added.
