This fixes some inconsistency issues when it comes to inner vs outer windows. On second patch I keep ref again to outer windows from the inner windows, and there are several reasons for this:
* It fixes the existing tests to match native IE. * It simplifies the code (it's always valid now, no second-guessing or what-ifs needed) and gets rid of `outer_window` in HTMLDocumentNode. * It **fixes** the `outer_window` in HTMLDocumentNode → it was basically prone to crashes in niche cases since it didn't hold a ref before. We can't couple it to the inner `window` field either, because that one gets detached, and that will fail *existing* tests. For example: `events.c:3224: Test failed: put_URL failed: 80004005`. * Instead of having to keep outer window refs in specific objects, it's simpler to have it consistent everywhere.
For now only the external caller changes are kept and a leak fix.

UIEvent.view is still todo_wine because it returns NULL for some reason, but it is clear from the existing tests that it must match the outer window.

This would cause a leak since we have a cyclic ref now.

For example `get_cookie` on a detached document would use URL from another document.

I'm still reviewing them, but I looked at get_cookie now, and I believe all the usages that use the document's `outer_window` currently should not be affected in any way.
Note that the doc's `outer_window` is permanently kept right now with no sort of reference other than at creation able to be NULL (for windowless documents created via `createHTMLDocument` for instance). After the patches, at least it becomes NULL when the outer window is killed instead of crashing/accessing invalid memory, so it actually has *less* impact.
That's why I'm reviewing only cases where we actually access it via `window->base.outer_window`, but let me know if I'm missing something…
