Which patch?

For the record, I have been pushing for this feature since a long time, and my latest proposal didn't receive any comments from Pidgin devs:
http://pidgin.im/pipermail/devel/2010-January/009177.html

My suggested patch for haze was in #26119.

It seems they added the API on 2.7.0 without even mentioning where the idea came from, nor discussing it with any potential users, and they aren't exercising it in any of their UI's. They decided it was a good idea to have callbacks without user_data pointers (silly IMO).

Anyway, fortunately it seems we don't need those pointers for now. I'm attaching a patch.
