This ports over a basic headerbar, maximize, and fullscreen. The
headerbar only has the main menu button for now since we have no tabbing
or splits. The main menu has the full main menu that mainline GTK has
but most of it is disabled since we don't implement the actions yet.
I didn't use anything from your branch @tristan957 so I didn't add
coauthor but I want to note that @tristan957 worked on this as well and
I suspect there's overlap.
This fixes a double-free that Valgrind found when the quit action was
used (the keybinding to quit or the menu item). This fixes it in both
the gtk and gtk-ng apprts.
The issue stems from the fact that our quit action worked by traversing
the toplevels and destroying all windows. When all windows are
destroyed, GTK exits the main loop.
When fcitx is used as the input method editor (IME), it appears to hold
its own `gtk.Window` widget as a property (probably for the IME popup).
Unfortunately this does not react well to being destroyed externally and
triggers a double-free when the IME widget also tries to dispose itself.
I think this is probably a bug somewhere in the GTK IME widget because
it should be resilient to this kind of destruction. But, we can't
tolerate a double free in the mean time.
We can still quit by destroying only OUR windows (which cascades to
destroy everything else).
