The goal is to catch cases where the return value exists, but is
forgotten. There was a large enough number of them to turn this
into a real check. Initially, I just wanted to implement it to fix
the problems, then delete the code. But since this is so common, I
think it is worth the annoyance.
This will allow the default client layout list to be manipulated by
modules without the risk of overwriting each other.
The commit also add a new `--{{{ Tag --}}}` section to `rc.lua`. It will
be expanded once the tag rules get merged.
This doesn't mean removing all screens is supported. It isn't and never
will be. The only reason this commit exist is to allow some
initialization and error handling code to be tested.
This way their name doesn't get mangle by the broken magic. It will also
eventually allow to `error()` in the template when the implicit
`@function` is used.
This commit also fixes a large number of issues found while
proof-reading everything.
Layouts work with the client's geometry in "space on screen that is
assigned to this client". This means that the geometry should include
decoration (titlebar and borders) and useless gaps.
Everything else (especially the C code) works with client's geometry in
"space that the client can draw on". This means that the titlebar,
borders and the useless gaps are not included into this size.
Thus, when applying size hints, the tile layout has to convert between
these two representations. Otherwise, size hints are applied incorrectly
and to a wrong geometry.

The magnifier layout handles the currently focused client specially.
However, if the currently floating client is floating, it should not be
handled by the layout at all. A bug caused the magnifier layout to
handle a focused and floating client anyway if it was the only tiled
client.
Fix this by removing the '#cls > 0'-case. If #cls == 0, then no client
is available to be managed. Thus, cls[1] will be nil, which is fine
since, well, no client is available to be managed. This only made a
difference in the specific bug that I described above. Thus, drop this
case.

When gap_single_client is set to 'false', no gap is used when only one
client is shown in a tag. Since the max layout only ever shows one
client at a time it makes sense to apply this setting for this layout
regardless of the actual number of clients in that tag.
Additionally, if the 'master_fill_policy' property is set to
'master_width_factor', then use a gap even if there is only one client
visible and 'gap_single_client' is false.
If an error occurs while a layout is being applied, arrange_lock could
get stuck at true, meaning that no more re-arranges will happen, thus
breaking the whole layout machinery.
Such errors could happen because the layout itself produces an error,
but also because a width is too large and c:geometry() throws an error.
Thus, this commit moves all of the actual "apply a layout"-code into a
protected context.

Just re-arranging on every focus change would cause useless/needless
re-arranges (which have no effect except to waste CPU time). Thus, this
adds a special (undocumented) flag on layouts that makes sure that a
rearrange occurs when the focus changes.

This commit doesn't add any useful documentation, but adds
previously hidden documentation variables. It can be the basis
of a better layout documentation.
Fix#1246
It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

The magnifier layout wants to ignore floating clients. Before 82342f0 this was
done by calling awful.client.floating.get(focus). If "focus" was nil, this might
have checked the floating status of a wrong client (if some other client was
focused, and the code in magnifier set focus=nil before). This issue can easily
be missed and might exist since forever. After 82342f, floating status is
checked via "focus.floating" and this now causes an "attempt to index nil value"
error instead. Much easier to notice.
Fix this by adding the missing nil check and while touching the code, merge this
with the previous "if" and correct another error (the wrong thing happened if we
had #cls=0).

Reported on IRC. I am not sure why swap() is not enough, but the
old code removed before the mouse refactor did this, so apparently
it is necessary.
The fix has been reported to work by spyroboy on IRC, thanks!
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.

to reproduce:
1) spawn an xterm
2) enter 'sleep 10 && killall xterm'
3) start moving the terminal
There will be an error
(found by a yet to be commited integration test)
If a screen is removed while a re-layout is pending, previously this code would
cause errors and problems. Since the screen is gone, there is nothing to arrange
anyway and we can just not do anything.
