Implementations of nsIEmbeddingSiteWindow and nsIBaseWindow largely overlap, and where they don't, the nsIEmbeddingSiteWindow implementation of the otherwise shared interface is primarily stubbed out with the exception of Get/SetDimensions(). This patch moves a reimplementation of Get/SetDimensions() from nsIEmbeddingSiteWindow to nsIBaseWindow. The other methods of nsIEmbeddingSiteWindow remain covered by nsIBaseWindow. Get/SetDimensions() can be implemented as part of nsIWebBrowserChrome where nsIBaseWindow is not necessary. This removes the need for nsIEmbeddingSiteWindow. Blur() has also been moved to nsIWebBrowserChrome, as only nsContentTreeOwner has an actual implementation which we in theory also want to call from BrowserChild/Parent, but the spec suggests to "selectively or uniformly ignore calls". GetVisibility() had an implementation in BrowserChild that pretended to always be visible. Instead of providing an interface for that, nsDocShell now handles the not implemented case for tree owners. nsIEmbeddingSiteWindow::GetSiteWindow() used to call through to nsIBaseWindow::GetParentNativeWindow(). The Get/SetDimensions() implementation has been replaced with a strongly typed setter, which is now also used directly from nsGlobalWindowOuter to avoid problems that come with autodetecting unchanged dimensions, when the current dimensions are outdated (e.g. immediately reverting a change can be ignored).
