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.

Wallpapers are usually big images that use up a lot of memory. This commit makes
gears.wallpaper call :finish() on all involved surface to make them free their
memory.
This is a lot faster than waiting for the garbage collector to collect these
surfaces. Due to the large size of wallpapers, such a special case makes sense
for this code.

Loading a file normally has the same behaviour as before. First the cache is
checked and if nothing is found, the file is loaded and cached.
This commit changes the behaviour of loading a file uncached. This no longer
removes the file from the cache if it is cached (why should it?) and also does
not put it in the cache.
This means that users of load_uncached and load_uncached_silently can now freely
modify the resulting surface without interfering with other API users.

This library is a wrapper around pcall() / xpcall() that prints an error message
via gears.debug.print_error() in case of errors.

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.
