The default config had tables like mywibox and mywibox[s] was the wibox
that is visible on screen s. When a screen is removed, nothing cleans up
these tables and so the screen and the wibox could not be garbage
collected. The same applies to the layoutbox, taglist etc.
This commit removes the global mywibox table and instead saves it as a
property on the screen. This way, the screen is not explicitly
referenced and when it is removed, the screen, its wibox and all of its
widgets become unreachable and can be garbage collected.
This commit also updates the docs and the tests that referenced things
(mostly the wibox) via mywibox[s] to now use s.mywibox.

Apparently, there is such thing as not leaking enough...
Also try to clear the widgets from mywibox. This seem to help.
Time will tell.
Fixes#914, unfixes #808
This commit makes all C code that previously returned a screen index now return
a screen object, continuing the deprecation of screen indicies. Note that this
is an API break and will likely cause all kinds of problems for users.
The change also breaks some tests which are suitably fixed in this commit.

When e.g. test-leaks.lua fails, it will cause a Lua error before starting the
test runner. This means that the test will just hang, because nothing causes
awesome to quit.
Handle this by starting a timer when the test runner is loaded and quitting
awesome in there if no test run was started yet. This only works if all tests
load the runner before doing anything that could fail, so the require("_runner")
is moved to the beginning in every test.

I have no idea why this needs collectgarbage() to be called twice.
On the other hand, I can explain the change in tooltip.lua. Lua 5.2 introduced
"ephermeron tables". This means that in the following sitation, lua 5.2 can
collect the entry from the table, while 5.1 keeps the entry alive, because the
table has a strong reference to the value and that in turn has a strong
reference to the key:
t = setmetatable({}, { __mode = "k"})
do
local k = {}
t[k] = function() print(k) end
end
collectgarbage("collect")
print(next(t, nil))
To handle this incompatibility, this commit just removes the whole indirection
through the module-level variable "data".

This commit does two things: It gets rid of the reference to the layoutbox that
the default config created and it changes the widget dependency cache to not
keep widgets alive unnecessarily.

Again, instead of directly connecting to various signals for updating a
tasklist, this commit changes the code so that there is just a single, global
connections and based on this a weak table with all tasklist instances is used
do the updates.

Similar to what the previous commit does for layoutboxes, this changes the code
for the taglist so that there is only a single, global connection to the various
signals and these update all taglists via weak tables.
