This library is a wrapper around pcall() / xpcall() that prints an error message
via gears.debug.print_error() in case of errors.

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.

Oh hey, Pango exports an API that allows to query for named colors based on the
famous rgb.txt! Let's use that!

This adds support to gears.color.parse_color to parse things like "#fff" (one
character per color component, without alpha) and "#ffff0000ffff0000" (four
characters per component, with alpha).
This makes sense on its own, but should also help with
https://github.com/awesomeWM/awesome/issues/585.

This adds a cyclic dependency between the function used for the weak signal and
an object with a __gc metamethod. The problem occurs since the GC will first
finalize the object (call its __gc metamethod) and only in the next generation
will it actually collect the garbage and remove the functions from weak-tables
using it as a key.
And yes this needs special code for Lua 5.1 because there __gc doesn't work on
tables. :-(

Since weak signals specifically exist to do magic with the garbage collector, do
a couple of garbage collection cycles and verify that this does not disconnect
the callback function prematurely (the function is kept alive since it is a
local variable).
(I actually did a mistake that makes this enhanced test fail and fixed it before
committing)

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.
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
recomputing the whole hierarchy whenever something changes.
Once again, this has some positive results on the "benchmark test":
Before:
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%)
and relayout (21%) are improved a lot.

This has some positive results on the "benchmark test". Each single number is
the best one out of three runs.
Before:
create wibox: 0.0826502 sec/iter ( 13 iters, 1.157 sec for benchmark)
update textclock: 0.0186952 sec/iter ( 57 iters, 2.473 sec for benchmark)
relayout textclock: 0.0158112 sec/iter ( 64 iters, 1.028 sec for benchmark)
redraw textclock: 0.0015197 sec/iter (662 iters, 1.861 sec for benchmark)
After:
create wibox: 0.0825672 sec/iter ( 13 iters, 1.154 sec for benchmark)
update textclock: 0.00378412 sec/iter (277 iters, 4.216 sec for benchmark)
relayout textclock: 0.00259056 sec/iter (420 iters, 1.09 sec for benchmark)
redraw textclock: 0.00105128 sec/iter (958 iters, 1.79 sec for benchmark)
We see no significant change in the creation of wiboxes (99.9% compared to
before). Update (20% of the previous run time), relayout (16%) and redraw (69%)
are all sped up by this change.

Instead of going through LGI to call cairo, this now implements the various
matrix operations directly in Lua. The plan is to avoid the overhead that we hit
due to LGI.

Before this, dependencies between widgets where implicitly discovered by
recursive calls to base.fit_widget() and base.layout_widget(). However, it is
too easy to get this wrong (just call one of these functions from outside of a
widget's :fit() / :layout() function) and the resulting mess would be hard to
debug.
Thus, this commit changes the API so that callers have to identify themselves
and we can explicitly record the dependency between the widgets involved.
This also fixes a bug where no dependencies were tracked for widgets after
:set_visible(false). Whoops...
Sorry for breaking the API for adding this.

These caches, well, cache the result of the :layout and :fit callbacks on
widgets.
Clearing caches is done by recording dependencies between a widget. When a call
to base.fit_widget() or base.layout_widget() recursively causes another call to
such a function, this means that the earlier widget depends on the later widget.
This dependency is recorded and when the later widget emits
widget::layout_changed, the caches of all the widgets involved are cleared.

This makes the tests for wibox.hierarchy use test_utils.widget_stub() instead of
having its own implementation of "fake widgets".

A widget hierarchy describes the position of widgets. The hierarchy is a
recursive tree of widget hierarchy instances. This functionality depends on a
:layout function that is not yet implemented on widgets, but will be added
later.

After this change, fit_widget() enforces that a widget cannot ask for more space
than was offered to it. This also fixes a rounding issue in the flex layout
where its fit function would return too small numbers.
Thanks to this, lots of "XXX" comments in spec/ disappear.

With version 2.0rc5, Busted started cleaning up between tests more thoroughly.
The result was that it managed to unload and reload lgi. However, the C part of
lgi is not safe to be reloaded. This caused sporadic errors in the test suite
runs.
Work around this via a helper script that is run before Busted starts running
tests. When we load lgi in this helper script, it is loaded before Busted starts
saving and restoring everything and thus lgi won't ever be unloaded.

Connecting to a signal weakly has the same effect as connecting to it strongly,
but it allows the garbage collector to disconnect the signal in case nothing
else references this function.

Busted now only provides the magic modules `assert`, `spy` etc for
the busted context. The helper module `spec/wibox/test_utils.lua`
therefore needs to explicitly require them.

This gets rid of awful.util.unittest and instead creates an automatic test for
it under spec/awful/util_spec.lua. In the process, it also fixes the test to
actually test the right thing and I took the liberty to add some more tests.

This uses busted (http://olivinelabs.com/busted/) to implement unit testing.
This is wired up to "make check" and/or "make test".
This commit also adds tests for the more complicated parts of the gears and
wibox.layout libraries.
