Regression in v4.1. It causes the `rc.lua` (and the fallback) to
exit when the wallpaper is missing or something went wrong.
In <= 4.0, the wallpaper wasn't loaded, but Awesome didn't "crash".
There should be no asserts in the code called during the first
event loop iteration.
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.

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

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.
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.

gears.surface now returns a fallback image surface that is good enough for what
this code tries to do here.

Usually users want a wallpaper on all their screens. With the current code, this
resulted in a loop of upload-wallpaper, {download-wallpaper, add-new-part,
upload-wallpaper}*.
Fix this by being more intelligent: Instead of setting the wallpaper
immediately, this now uses gears.timer.delayed_call() to set the wallpaper. All
following modifications which come in before the delayed call runs will still be
part of the current update. This should mean that during startup, there is just
a single upload of a wallpaper.
(The above is what happens if there is no wallpaper yet. If there is already
one, we use :create_similar() and thus should only upload the part of the
wallpaper that changed, but this doesn't really make a difference.)
As a side-effect, the new code no longer draws to the old wallpaper to modify
it, but always creates a copy of it. This means that:
