This extracts the code for finding the next screen
from focus_bydirection to a separate method on
the screen object.
The main reason was to use the finding code without
actually changing the screen focus but this should
incidentally make the code slightly easier to test
as well since both concerns can be tested in
isolation.

This makes things fail loudly which otherwise fail without giving a hint
on what went wrong.

If the caller provides a file name, these function load the image, set
it as the wallpaper and make sure that the memory used for the image
data is freed immediately. However, this was also done when the caller
provided a cairo surface, thus breaking their surface.
Fix the code so that it does not finish surfaces that it did not create
itself.

Also save some boilerplate code.
This closes the gap between timer.start_new and timer.new. Now the
only difference is that one have a special callback format while
the other only has predefined properties.
We already have a variant of this function for transforming an actual
matrix. This adds the corresponding static factory.

For some reason, the code here tried to handle widget::redraw_needed
signals even though it should apparently/obviously only produce a
current snapshot of the widget's look.
Fix this by just removing the redraw code.
While here, also factor out the widget context table into a local
variable and re-use it for the initial layout and for the later draw.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

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.

All other shape did it. While it usually have no side effects,
as seen in #920 screenshot from @actionless, there is instances
where this produce a invalid rectangle.
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.

Similar systems already exist un luaobject, wibox and the declarative
widget system. This close the gap and also bring the property based
syntax to wibox and other gears.object users.
While this need to be enabled explicitly for legacy reasons, it
doesn't break the API.
Once widespread, this implementation will replace the one found
in wibox.widget.base_widget.
