Checking most of this in now, closing the patch.

Latest version uploaded (the SF glitch seems fixed).

Just for fun, this adds warnings for raising string exceptions and raising class exception that aren't derived from Exception, and it also adds warnings to the functions in the string module and to the strop module.

These need work, but give an indication that this is a useful feature: it caught lots of offenders in the test suite!  (Patches to sre.py and sre_parse.py included.)

Assigning to Barry if he wants to review it.

I have a new version fof warnings.py that fixes a few nits, but there's a problem with SF that prevents me from uploading it.  Mail me.

Comment:
All the C code is redone, to postpone the import of warnings.py until PyErr_Warn() is actually called.  This should also be more robust in the light of multiple interpreters (no globals are used).  The warning category exceptions are now created as standard exceptions.

The Python code redone for the new situation, and with some of Paul Prescod's suggestions implemented.

Comment:
Here's a more elaborate version of the patch, that adds the C API.

(The C API imports warnings.py though.)

Note that in contradition to PEP 230, the C routine to issue a warning is called PyErr_Warn(category, message) rather than Py_Warn(message, category).  This is open for discussion.  Since the category is a kind of exception, it seems to make sense to be consistent with the other PyErr_*() functions rather than with the Python warn(message[, category]) function.
