This new function is called whenever the visibility of the drawable
changes. Later commits can use this for explicitly tracking the lifetime
of drawables instead of using magic weak tables.

For a while, it was often suggested on IRC to replace the default
request::activate handler to implement custom focus stealing policies.
While it is working, it isn't user friendly. This commit add a simple
mechanism to add such policies.
This adds a tparam alias "@screen" for "@tparam screen" (when used to
document e.g. arguments for callbacks), and "@screen_or_idx" when a
function accepts a "screen" or "number".
The default config had tables like mywibox and mywibox[s] was the wibox
that is visible on screen s. When a screen is removed, nothing cleans up
these tables and so the screen and the wibox could not be garbage
collected. The same applies to the layoutbox, taglist etc.
This commit removes the global mywibox table and instead saves it as a
property on the screen. This way, the screen is not explicitly
referenced and when it is removed, the screen, its wibox and all of its
widgets become unreachable and can be garbage collected.
This commit also updates the docs and the tests that referenced things
(mostly the wibox) via mywibox[s] to now use s.mywibox.

Previously, gears.object.properties used a weak table for adding
additional information to a C object. However, weak tables can easily
cause leaks when the value references the key.
This commit makes the code instead use the new .data property that is
available on all C objects. This means we have no more magic with a weak
table and instead only use "regular" tables instead.

This restore a feature that was available in Awesome 2.1-3.2.
The reason margin is implemented rather than use a container is to
be able to make the background smaller than the bar.
The current progressbar code dates from a time when Awesome had
a very limited drawing API. This commit first re-write the
algorithm to remove the workaround used to draw the border using
full rectangles only. It then add support for outer and inner
shapes with their respective border settings.
This commit also add clip support. This is enabled by default, but
could be disabled to have the bar taller than the background.
Twice now we had problems with the garbage collector which caused signals
established via weak_connect_signal() not to be disconnected when we wanted them
to be disconnected. The effect was that we tried to redraw a drawable after it
was garbage collected which caused errors.
Instead of playing whack-a-mole with all the various ways that might make us
redraw a drawable after GC, let's just fix all of these issues by explicitly
checking for this case and turning it into a no-op.

The previous commit made wibox.drawable turn a "normal redraw" into a complete
repaint when it was moved to another screen. However, nothing happened until
that normal redraw.
This commit triggers a normal redraw when we are (possibly) moved to another
screen. More precise, this means that whenever a screen appears, disappears or
changes its geometry and when the drawable is moved, we trigger a normal redraw.
This redraw will likely do nothing, because no relayout is pending and no part
of the surface needs a redraw, so it is cheap.
However, if the drawable really ends up on another screen, then the code from
the previous commits makes us do a full relayout and redraw.
This commit likely fixes the current instability of test-screen-changes.lua. See
https://github.com/awesomeWM/awesome/issues/982#issuecomment-231712056.
As explained there, the test fails because the fake screen that it created is
still referenced, so cannot be garbage collected, but the test doesn't succeed
unless the screen is garbage collected. So something is still referencing the
screen that was removed. This something can be a client's titlebar, because the
underlying drawable still has a context member referring to the old screen.
This commit should fix that problem, because we now trigger a redraw which will
compute a new context and thus the reference to the old screen is released.
