In non-composited environments, we were ending up with all-black
drag icons, because nothing was drawing the background of our new
toplevel. Fix this by drawing background when we are not composited.
We don't do this when composited, since we want to allow transparent
icons.
GtkPlacesView currently provides no example of
server addresses, which may confuse users.
To fix that, add a helper popover with some
guidance on server addresses.

The documentation clearly says that the widget is not destroyed,
but we were in fact failing to keep it alive, since it was still
a child or the icon_window when we destroy that. Fix this by
reparenting the icon_widget out before. Also, deal with the
possibility that the application might destroy the widget
halfway through, for whatever reason.
There are various functions to access links based on their index for
a11y. We can spare quite a few lines of code by just using
g_list_nth_data instead of iterating over the list ourselves.

We perform lots of gadget allocations that require allocating a
GtkBuiltinIcon. One notable example is the scrollbar for a scrolled
window.
In the process of doing this, we often calculate baseline information that
isn't necessary. With how much this code path gets exercised, its worth
catching the result for the common case, which is that the font-description
has not changed and we are using the default language the application
was started with.
This simply caches the previous result and verifies that we can reuse it
with pango_font_description_hash() and a simple language check.
Numbers below are scrolling through a textview with GDK_KEY_Down.

When decelerating the kinetic scroll, we can get into a position where it
looks like we are stuttering. This happens because the amount we move is
so little that it takes multiple frames to make forward progress by one
pixel.
This prevents that by detecting when we have reached the slow stutter of
the deceleration and simply stops the deceleration phase immediately.

This has several benefits:
- Less code in GtkApplication. The accels handling is something
self-contained, and GtkApplication now delegates the work.
- For the accels functions, there is now a distinction between static
functions and functions in the gtkapplicationaccelsprivate.h header,
which makes the code easier to understand, because we have a good
overview just by reading the header.
- The struct _GtkApplicationPrivate is now easier to find instead of
being in the middle of the file.

These will become the functions present in the
gtkapplicationaccelsprivate.h header.
The gtk_application_accels functions deal with detailed_action_name's
instead of action_and_target's. action_and_target is an implementation
detail of Accels.
The added function prototype is temporary, it'll be removed in a later
commit.

When the current cursor_row is taller than the page_size we get from the
GtkAdjustment, the previous code would not actually cause any scrolling,
so make sure we just take the row after or before the cursor_row in that
case.

These runtime checks were being performed whether or not we were in a
debug build. Using GTK_DEBUG_CHECK() will compile out of production
builds, as it will result in something like:
if (G_UNLIKELY(0))
which the optimizer can prune.
