Dan Mašek 8c1d8eccdd Merge pull request #11207 from dan-masek:add_redirect_error
* Add Python support for error message handlers.

* Move the static variable to the only function that uses it.

* Remove the optional param (user data), since this can already be handled by closures.

* Correct the help string.

* python: added redirectError test
