The tag history kept a strong reference to a screen even after that
screen was removed. This prevented the garbage collector from cleaning
up.
Fix this by getting rid of the tag history on screen removal.

Right now, there is still a memory leak *only* when there is active
`box` notification when the screen is removed. I failed to identify
where *this* leak is comming from. The previous few commits fix
~5 other leaks.
The API level concept is something used by other projects such as
Android and iOS to allow deprecated features to be removed and the
bahavior to be altered without breaking compability with existing
code.
The same will apply to AwesomeWM. The current API level is "4" and
as long as config use this, no deprecation or bahavior change will
be exposed. If the user sets it to an higher value or we release
the next major version and new users start to use the, then current,
default config, they will use the new API level.
The the far future, if ever, we could fork the entire Lua libraries
to support legacy APIs. This would only require to keep the core
API support for those legacy calls. In the meantime, `gears.debug`
will use this to manage the deprecation and some conditional code
will be added as a last resort attempt to preserve behavior
compatibility while moving forward with breaking changes.
The next commit will add modeline support. By default, modelines have
the final work on which options to set. However, mostly for testing,
this isn't flexible enough.
From now on, all core object will have their own rules. `awful.rules`
hardcodes some client specific code. All `rules` module have some form
of class specific code. This code will now be part of a new module
called `ruled`. Since a year or so, a lot of work has been done to
refactor the rules on top of the shared `gears.matcher` class. This way
there wont be as much duplication.
The default `rc.lua` was using the focus/unfocus signals to set
the border color along with `awful.rules`. This logic block was
no longer aligned with the rest of `rc.lua` since it was
the only place where `beautiful` variables where only used by
`rc.lua`.
On top of this, the new request handler also has extra contexts
for the urgent and floating/maximixed use cases. So it can be used
by themes to implement much smarter borders than just focus based
ones. They were previously limited by the fact most of the
(un-monkey-patchable) logic was in `rc.lua`.
Note that this commit also shuffle the awful.rules order between
the titlebar and the border and changes the tests accordignly.
After some consideration, I came to the conclusion the previous
behavior was bogus and the fact that the placement tests required
to know about the titlebar height is simply a proof of that. The
change was required in this commit because since the border is no
longer in the default rules, a new buggy edge case surfaced.
They currently fit the general concept of a `request::` in the sense
that they are not property related and have "request handlers".
The commit also add deprecation for signals.
The reason for this fits within the larger standardization project.
Non-namespaced signals will eventually be renamed. This has started
a long time ago.
What is old is new again. Once upon a time, there was a `startup`
parameter to the `manage` signal. It is now back in the form of
a context.
Finally, this commit removes the `manage` section of `rc.lua`. It no
longer did anything worthy of being in the config. Each of its
important parts have been moved out over the years and the last
remaining bit is always required anyway. The code has been moved
to `client.lua`.
* Add a better descrition for the `imagebox` role in the wiboxes system ;
* Improve image + code render and integration into the descrition ;
* Add a second code exemple to show both coding style (imperative and declarative).
I think the user can now have a better overview of what's a `wibox.widget.imagebox` and how to use it.
Change how wibox are drawn to build a more flexible function reusable in the context of clients.
Add `clients` option to the template. This new option needs an associative table `{ ['label'] = client }` to work. Where label will be a text rendered on the middle of the client area.
Add a new example: `texts/examples/screen/tiled_clients.lua`.
Rulers insertion order impact the result of the bubble sort algorithm.
By inverting the order, we can make the output image looking more natural.
Awesome's screen properties can be seen like this:
* The screen has a geometry (its size) ;
* Inside there is the workarea ;
* Inside there is the tiling_area.
It seems better to draw rulers in this order.
