Make toMimeDataWithFile() handle writing files to the in-memory file system correctly: this is an async operation and we need to collect the files as the writes complete and then invoke the callback once all files have been saved. There's then no need for a global static QMimeData. Use toMimeDataWithFile() for both the paste and drop handling, however QPlatformClipboard::setMimeData() takes ownership of the passed in QMimeData and the callback API must be designed accordingly. An open question is when we should delete the files. Deleting them right away (after calling the app event handler) is predictable, however it looks like QPlatformClipboard::setMimeData() retains the current QMimeData until a new one is set, so maybe we should follow that.
