Patch by Stefan Behnel.

Add INCREFs, fix args->kwargs, and a second args==NULL check was removed,
left over from a merger with another function. Instead, checking msg==NULL
does what that used to do in a roundabout way.

Currently import does not use these attributes as they are planned
for use by importlib (which will be another commit).

Thanks to Filip Gruszczyński for the initial patch and Brian Curtin
for refining it.

So it would be possible to support more error handlers later.

works properly.

PyErr_SetFromErrnoWithFilenameObject() was already fixed by the changeset
793c75177d28. This commit fixes PyErr_SetExcFromWindowsErrWithFilenameObject(),
used on Windows.

"except" works properly.

PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
filesystem encoding instead of UTF-8.

This crases the interpreter if this precisely happens inside PyErr_SetObject.

- now the __context__ is properly preserved
- in any case, PyErr_SetObject now saves the current exc_value in a local variable, to
avoid such crashes in the future.

  Re-implement the 'warnings' module in C. This allows for usage of the
  'warnings' code in places where it was previously not possible (e.g., the

  Python version in key places.
