This prevents warnings like
(gtk3-demo:14948): Gdk-CRITICAL **: _gdk_frame_clock_thaw: assertion 'GDK_IS_FRAME_CLOCK (clock)' failed
(gtk3-demo:14948): Gdk-CRITICAL **: gdk_frame_clock_get_timings: assertion 'GDK_IS_FRAME_CLOCK (frame_clock)' failed
We need to do this, as the compositor might have already sent us a frame
event, in-flight, at the same time we destroy our window. In this case, we'll
receive the then-in-flight "done" event, and then warn as we try to look
up the frame clock on a destroyed window.
disconnect_by_func() is slow, and this becomes particularly evident
when disposing a number of widgets (and their associated style
context) at once, such as when using a language binding which
uses a GC.

It seems that alternate implementations of GtkFileChooserWidget
never materialized. The split between GtkFileChooserWidget and
GtkFileChooserDefault is awkward. The immediate problem is that
it makes it difficult to document the keybinding signals. So it
makes sense to drop the abstraction and just have one thing.

The button press/release handlers did invariably return FALSE, even
though it shouldn't if a row was found on the event coordinates. Also,
use GDK_EVENT_* defines for the return values.
The minimal size if no child widget was present/shown was far too small
to have enough room for the arrow width plus border radii, so
gtk_render_frame_gap would spew warnings about the gap being out of
boundaries.

If the grab is released during button press, the button release is
just then sent to the widget below the pointer. Depending on the
widget implementation, this could already trigger actions if the
widget does not perform any kind of button state tracking. It is
safer to ungrab on button release so no extra actions are possibly
triggered, and the behavior is uniform across widgets.
But the opposite situation may also happen, that a popover is
shown/grabbed on a button press event, so it'd get the sole button
release event after being shown, so prepare for that case by making
popover ignore single button release events with no preceding button
press.
