annotate Python/errors.c @ 36751:8e04de2480e4 legacy-trunk

PEP 352 implementation. Creates a new base class, BaseException, which has an added message attribute compared to the previous version of Exception. It is also a new-style class, making all exceptions now new-style. KeyboardInterrupt and SystemExit inherit from BaseException directly. String exceptions now raise DeprecationWarning. Applies patch 1104669, and closes bugs 1012952 and 518846.
