Summary WebKitGTK+ crashes when cancelling plugin loads

If you go to a page that uses plugins such as flash, and click a link or cancel the load, the browser will crash. Investigating the problem I found out that our ResourceHandle implementation calls didFinishLoading in it's cancel method, which is completely bogus, the way I understand the workflow, and is not done by any other ports except for the Windows (WebCore/platform/network/win/ResourceHandleWin.cpp) port. I made a patch removing the calls to didFinishLoading, and tested with acid2, acid3, and the webkit layout tests, and found no regression. The crash is also gone.
