widget_at() no longer exists since 0aa4304bda (and the surrounding commits
stopped us using this function).

The requirement to call add_signal() was added to catch typos. However, this
requirement became increasingly annoying with property::<name> signals and e.g.
gears.object allowing arbitrary properties to be changed.
All of this ended up in a single commit because tests/examples fails if I first
let add_signal() emit a deprecation warning.

Before this commit, it was necessary to call 'rawset' to be
able to add new fields to the wibox. This is no longer required.
This solution was choosen because wibox is itself a base class of
menus and wibars. Those classes can now add new properties without
hacks.
As wibox contain a drawin, but isn't one, it is necessary to map
drawin to wibox.
This could eventually be fixed by turning wibox into drawin just
like the client, tag and screen do.
It's unused since commit 0aa4304bda. Before this was a stable sorting
algorithm since table.sort is allowed to be unstable. Apparently we don't need a
stable sorting algorithm anymore.

A widget hierarchy describes the position of widgets. The hierarchy is a
recursive tree of widget hierarchy instances. This functionality depends on a
:layout function that is not yet implemented on widgets, but will be added
later.

This table contains the drawable, wibox and titlebar that we are drawing on, but
also includes the screen and the DPI of that screen. This allows widgets to
depend on the DPI in their rendering.
