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.

This makes awful.tooltip create its tooltip lazily when it is first needed
instead of immediately when the tooltip is created.

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 is used by `tooltip.place` then to tie the tooltip to the screen of
the mouse. Without this, a tooltip from the tasklist might get moved to
the screen above the tasklist, if it gets considered to be on that
screen given its coordinates.
Closes https://github.com/awesomeWM/awesome/pull/437.
The tooltip might be partly outside of the screen, and especially the
workarea, e.g. for tooltips on the tasklist.
Calling `awful.placement.no_offscreen` makes sure that it is fully
inside, and will even restrict it to the workarea, not only to the screen.
Closes https://github.com/awesomeWM/awesome/pull/409.
Because of `placement.under_mouse` (and without
`placement.no_offscreen` fixing it), this will cause the tooltip to hide
immediately again.
There is no need for hooking into this signal, but this adds a click
handler to close the tooltip when clicking into it.
This splits the logic for `delay_show` out of `show`/`hide`, and handles
an already stopped timer. The timer gets also stopped after the tooltip
has been displayed.
