Comment 1 for bug 1199445

I'm thinking that we should drop our KatzeHttpCookies(Sqlite) and move to using SoupCookieJarSqlite with a changed callback to enforce policy. With WebKit2 we'll not use libSoup directly and this is the only approach available. We require 2.27.90 these days so that is feasible. It would also reduce code in core, and we can leave any non-trivial features to the extension.
