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.
The code in gears.wallpaper currently sets a wallpaper in a deferred fashion.
Only a while after it is told to do something does it actually do the wallpaper
change. This is to incorporate many wallpaper changes right after another. These
changes happens during startup where the wallpaper for each screen is set one
after another.
However, since we no longer restart on RandR changes, the screen configuration
could change while we have a pending wallpaper. In this case, part of the
wallpaper could be "chopped off", because the surface that we draw the wallpaper
to is too small.
This commit makes gears.wallpaper track the size of the pending wallpaper and
create a new surface if the already-pending one is too small.

gears modules usually don't depend on Awesome C-API. This code has
been placed there for unclear reasons.
Also, there is ongoing work to unify each "concepts" API into one
single page. Having `gears.screen` go against this effort.
This adds gears.screen which contains a wrapper around
screen.connect_signal("added", func) that also calls the callback function for
each screen that already exists. This is added in gears.screen so that it can
also be used from e.g. wibox, if needed. Feel free to move this elsewhere if
that's a bad idea (I'm not really convinced of it).

Instead of using a special _call field on gears.matrix instances which has to be
copied around suitably, this commit changes the code so that the magic is
restricted to a single function in gears.shape.transform. With some metatable
magic, suitable redirection to everything is added.
