Most of the entries that are marked as "TODO: Get rid of these" were
handled. wibox.layout.align:get_children() never worked (it always
called a non-existent function), so we can easily fix this entry without
introducing a regression.
I opened https://github.com/awesomeWM/awesome/issues/1672 to track the
underlying problem behind the broken :get_children() function (which is
missing test coverage).

This commit changes the systray widget, wibox.drawable and the C code to
fix the following bug: When the systray widget is removed from a
drawable without being moved somewhere else, the systray stayed visible.
This was because the systray is not drawn by awesome, but only placed.
When the widget is no longer "drawn", it stays wherever it was placed
last.
This change works by detecting the situation when the systray is
removed. Then, the C code is specifically told to remove the systray
window from the drawable.
Note that this is only a partial fix. This change works correctly when
the widget is removed completely, because it is no longer placed by its
parent widget. However, for example, when you do
wibox.widget.systray().visible = false, the effect is just that the
systray widget gets size 0x0. This is not really visible, but as far as
this change is concerned, the widget is still part of the drawable.

This adds new code so that we can count how often a specific widget is
visible inside of all widget hierarchies.

Remove matrix and add superpose property
Update documentation, remove beautiful dep
Add insert, extend and remove columns and rows
Change x and y to horizontal and vertical
Creating a widget already sets a metatable (at least these days).
However, wibox.container.scroll overwrote this metatable with its own
metatable. This commit removes this overwrite.

It should be called "align", but the name is already taken
It doesn't use awful.placement because it would break the dependency
graph.
Some cases previously required 2 wibox.layout.align layouts,
one for each axis. This is massively overkill to simply place
a widget at the center of a larger area.
This bridges between gears.shape and the shapes. So far, it does not try
to do any kind of anti-aliasing magic, so you get "steep edges".

Up to now, a drawable always figured out the screen that it is on by
looking at its position. This causes memleak-like problems with wibars:
A wibar has a screen assigned, but its underlying drawable will end up
referring to another screen. Via this, we were managing to build a long
reference chain of screens and drawable that meant that none of the fake
screens that our test suite added could be garbage collected.
To fix this, add wibox.drawable._force_screen(s). After this function is
called, the normal screen detection based on the position is skipped and
instead the given screen is always used. This breaks the above reference
chain and things become garbage-collectable.
Also, this chains the drawable to the life time of the screen: When the
screen becomes invalid (.valid == false), the drawable will stop
redrawing.

Previously, the API to set the data that should be displayed was
:set_data(t) where t is a table. This table has the labels to use as its
keys and the numbers as its values. With this API, it was not possible
to influence the order in which the "pie pieces" were drawn.
This commit adds and uses a new API called :set_data_list(t). Here, t is
a table with integer keys and tables as values, thus one can iterate
over this with ipairs() and the order is well-defined. The tables used
as values contain the label as their first entry and the number as their
second entry.

No idea what self referencing loops this refers to. Lua 5.1's and
LuaJIT's garbage collector both should handle cycles just fine. Things
only start getting complicated when you start using weak tables.
Unless someone comes up with an example where this patch causes a leak,
let's remove the weak table magic.

Matrix operations are hard. Apparently I always keep confusing the order
that transformations are applied in the matrix resulting from a matrix
multiplication.
This commit fixes things in wibox.hierarchy that were wrong due to the
wrong order and changes a unit test so that it would now catch the
breakage (and makes sure that it does not happen again).

Instead of matrix_to_device and matrix_to_parent, this now provides the
full hierarchy instance managing the current widget.
In addition to x, y, width and height (which are an over-approximation
of the widget's extents on the drawable), this now also provides
widget_width and widget_height in the widget's local coordinate system.
These last two values are exact.
For example, the tooltip needs x/y/width/height while a widget that
wants to figure out which point on it was hit with a mouse press will
need widget_width and widget_height (together with the position argument
that is passed in with mouse::press).
I don't know how to document the return type of this function properly.
Hopefully just describing the structure of the resulting table is good
enough.

Similar to the previous commit, this makes the drawable not apply a
pending relayout while it is not visible. When it becomes visible again,
the relayout is done.
The hope here is that less work is done while a drawable is not visible,
saving CPU time.

LGI does not protect against use-after-free issues that can occur due to
using an object after finalisation. This manifests itself as occasional
crashes on Travis in cairo_region_union_rectangle() (AFAIK no one ran
into this issue in real-world usage).
Since visible drawables are always strongly reachable, the issue can
only occur with invisible drawables. The previous commit made sure that
those are fully repainted when they become visible, so we can just
ignore redraws for those and fix the crash issue.

Instead of tracking all drawables that are alive, the code now only
tracks visible drawables. When a drawable is made visible it is
completely repainted. This should not cause a difference when a wibox is
initially made visible, because it has to be redrawn anyway. However,
this introduces a full repaint when a wibox is hidden and then made
visible again.
Thanks to this change, we can stop using weak tables. Visible drawables
cannot be collected and so we can keep a strong reference to them. This
allows us to get rid of the weak tables which solves various problems
involving finalizers and using objects after finalisation.

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.
