This new syntax is inspired by the Awesome widget 3.2-3.4 API. It
allow cleaner widgets declaration. The produced code is usually much
shorted and easier to read than wibox.widget imperative syntax.
There is already a hack into `awful.widget.common`. This system aim
to make the hack obselete while preserving the useful part.
I think this is also necessary to properly support SVG (with DPI
and resize).
Finally, Qt handle this using the QBrush concept, where you can have
programmatic patterns. Cairo doesn't have this concept, so there is no
"clean" way to have programmatic brushes.
It's unused since commit 0aa4304bda. Before this was a stable sorting
algorithm since table.sort is allowed to be unstable. Apparently we don't need a
stable sorting algorithm anymore.

Any awful.titlebar.widget.button widget (e.g. floatingbutton or closebutton)
decides on the currently visible symbol based on several factors. One of them is
"is the client currently focused?" and thus the button has to be updated when
the client is focused/unfocused.
The way the code did this was to use client.connect_signal("focus", f) and
client.connect_signal("unfocus", f). However, these signals are never
disconnected and kept alive forever. The callback function had a strong
reference to the client (as an upvalue) and thus this also prevented the client
from being garbage collected.
Fix this by using c:connect_signal("focus/unfocis", f) instead. These kind of
signals are only kept alive by the client object and don't prevent it from being
garbage collected.
This fixes the new test that the previous commit added.

Until now, this layout was "append only". There was no official
APIs to remove, replace, insert and swap widgets. This is fine
for the usual wibox + sensors widget used by the majority of
users, but lack flexibility necessary to use the layout system
to place dynamic elements such as clients.
The methods introduced by this commit are also recursive. This
allow widgets to be decorated, wrapped and splitted without
having to add boilerplate code everywhere.
This remove duplicated code and will allow more "collection"
style layouts to be implemented without logic duplication.
This commit also do some small cleanup to remove duplicated
code now present in `awful.util`.

Go around a limitation of the lua language spec. The return value
of this method guaranteed `ipairs()` correctness.
Please note that both the official Lua and Luajit implementation
provide a sparse table compatible `ipairs()` and __len implementation
by default.
It is an internal API and is used by `gears.shape`, `gears.pattern`
and `gears.composition` only.
This commit also add `:rotate_at` and `:copy` methods.
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.
Before, it was the caller job to make sure the client wasn't floating.
This limitation is unecessary. awful.client.idx now return nil instead
of an error. awful.rules setting the master width factor are now
foolproof.
This code is imported from Elv13 config and make it very easy
to create shaped objects.
If accepted upstream, other shapes, such as arrow and powerline
will also be added. This commit introsuce the 2 most common
shapes, rounded rectangle and rounded bar.
This allow the most basic kind of stateful layouts to be created.
It is now possible to have layout instances instead of global
stateless layout arrange functions.
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.

Lua will remove objects as values from a weak table before these objects are
finalized, but as values only in the next garbage collection cycle after the
object was finalized. Up to now, gears.object uses a table with weak keys so
that :disconnect_signal() works. This means that a signal can still call methods
which were already considered garbage by the garbage collector and thus can use
userdata from the C side which was already finalized. Crashes and other bugs
result.
This commit changes the code so that the function is also a value in the weak
table. Thus, the GC will remove the entry before the object is finalized.
Special magic is needed for Lua 5.1, because there only userdata has the
behavior that we want while we have a function. We do some magic with function
environments to make this work...

When emitting layout_changed, the widget is relayouted. If this doesn't actually
change anything, nothing will be redrawn. Thus, this also emits redraw_needed to
force redraws.
This fixes a race condition with some weird tray icons. A new tray icon is
created and the systray is updated. Then this new icon is destroyed immediately
again and at the same time another icon is created. Then, the systray isn't
updated since the number of icons (=the layout) did not actually change.
However, it needs to be updated and so we ended up with broken/missing icons.

Usually users want a wallpaper on all their screens. With the current code, this
resulted in a loop of upload-wallpaper, {download-wallpaper, add-new-part,
upload-wallpaper}*.
Fix this by being more intelligent: Instead of setting the wallpaper
immediately, this now uses gears.timer.delayed_call() to set the wallpaper. All
following modifications which come in before the delayed call runs will still be
part of the current update. This should mean that during startup, there is just
a single upload of a wallpaper.
(The above is what happens if there is no wallpaper yet. If there is already
one, we use :create_similar() and thus should only upload the part of the
wallpaper that changed, but this doesn't really make a difference.)
As a side-effect, the new code no longer draws to the old wallpaper to modify
it, but always creates a copy of it. This means that:

If someone modifies a cairo surface and then sets the resulting object as the
image of an imagebox, the imagebox needs to redraw. Thus, since surfaces are
modifiable, we cannot assume that nothing changed when the same image is set
multiple times on an imagebox.
However, the dimensions of a surface cannot be changed and thus this does not
need to emit widget::layout_changed.

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))

Instead of connecting to the needed tag-update-signal again for every layoutbox,
this now just creates a single connection and updates all layoutboxes from here.
A new weak table is used to find the layoutboxes from these callbacks.
Additionally, layoutboxes are now per-screen unique. So even if you try to
create three layoutboxes for screen 1, the code will now always return the same
instance.
This kind-of fixes the leak test for layoutboxes. The problem is that the
default config also creates a layoutbox and adds it to a wibox. Since this is
now the same layoutbox, the test still fails. Just removing the layoutbox-part
from the default config makes this problem go away.

This fixes the textclock-specific part of the test that the previous commit

To fix this, gears.timer.weak_start_new() is used. This function creates a timer
that is automatically stopped when its callback function is garbage collected.
The callback function is saved as a member of the texbox widget that is the
"widget behind the textclock". Thus, the timer can only be stopped after the
widget is garbage-collected, but the timer does not keep the widget alive.

The way of icon path lookup for `menubar` is enhanced so that it is
based on a theme-oriented way as described in the specification:
Icon Theme Specification, Ver. 0.12
http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html
To accomplish this:
* Add the two new files `icon_theme.lua` and `index_theme.lua`.
The former implements an icon lookup algorithm suggested in the URL
above. The latter implements a helper object to parse the cache file
`index.theme` of which data is used by the former.
* Modify `menu_gen.lua` to use the new algorithm.
- The implementation of `lookup_category_icons` is changed
accordingly.
- The values of the field `all_categories.icon_name` are changed file
names to icon names, i.e., file extensions which are used to
indicate image file formats are removed.
* Add the new file `icon_theme_spec.lua` for a unit test for checking
if `icon_theme.lua` together with `index_theme.lua` works as
expected.
When a client is not visible, this would adjust its stacking order
still.
This also addresses https://github.com/awesomeWM/awesome/issues/472,
because it raises unminimized clients after they got focused.
This function updates a hierarchy if the layout of some widgets changed. It does
nothing on the parts that did not change. This should be more efficient than

create wibox: 0.083016 sec/iter ( 13 iters, 1.161 sec for benchmark)
update textclock: 0.00391091 sec/iter (271 iters, 3.219 sec for benchmark)
relayout textclock: 0.00273234 sec/iter (397 iters, 1.087 sec for benchmark)
redraw textclock: 0.0010191 sec/iter (989 iters, 1.745 sec for benchmark)
After:
create wibox: 0.083146 sec/iter ( 13 iters, 1.163 sec for benchmark)
update textclock: 0.00170519 sec/iter (647 iters, 2.201 sec for benchmark)
relayout textclock: 0.000581637 sec/iter (1880 iters, 1.094 sec for benchmark)
redraw textclock: 0.0010167 sec/iter (997 iters, 1.773 sec for benchmark)
So again no difference for creating wiboxes (100.16% compared to before). This
time we also have no real difference for creating wiboxes (99.76%). Update (44%)
