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.

Any signal on a screen instance is also emitted on the screen class, so the here
can just connect to the screen class.

There seem to be a little race condition (either in my layout code or
elsewhere) when playing with multiple screens. As most properties do
not depend on the tag, there is no point in returning early anyway.
Because all our Lua code can now work with screen objects, most of the uses of
s.index that the previous patches added for reaching this goal can be removed
again.

This commits makes a random selection of modules in awful support screen objects
and accept them as parameters everywhere where a screen index is accepted.

awful.layout.suit.corner does awful.tag.getmfpol(t), but doesn't actually have a
variable t in scope. I just copied the needed stuff from the tile layout.

It is necessary to have it beforehand when creating layout objects
for unselected layouts.
In the current layout system, there is no layout object, but to allow
tabs and dynamic tagging features like ion3, layouts cannot be stateless.
This allow layout "arrange" to be called less often and react on
the cause of the change itself rather than it's consequences
(usually, the "focus" signal).
Previously, the layout were re-arranged everytime the focus changed.
Now, with "raised" and "lowered", it require less "arrange".
"swapped" allow smarted layouts. Currently, swapped cause a full
re-arrange. It re-read the "index" list from scratch and create
a "new" layout. With "swapped", incremental layout changes are
possible.
