We have many places where we are sending an XCB request and expect an
answer where the protocol guarantees that no error can occur and we are
sure to get an answer. However, for example if the X11 server crashes,
these places can still fail. This commit tries to handle failures at all
these places.
I went through the code and tried to add missing error checking (well,
NULL-pointer-checking) to all affected places.
In most cases these errors are just silently ignored. The exception is
in screen querying during startup. If, for example, querying RandR info
fails, we will fall back to Xinerama or zaphod mode. This is serious
enough that it warrants a warning. In most cases, we should exit shortly
afterwards anyway, because, as explained above, these requests should
only fail when our connection to the X11 server breaks.

People who use a plain "make install" to install awesome will likely
also use the same approach to update their installation. However, this
does not actually work, because in awesome 3.5 there are beautiful.lua
and naughty.lua. These modules have since been split up into multiple
files and we now have beauitful/init.lua and naughty/init.lua instead.
The result is that the newer awesome will use some code from an older
version of awesome.
This commit has a work-around for this: We add "empty" beautiful.lua and
naughty.lua files whose only purpose is to load the real file. These
"empty" files will then overwrite files from an older installation and
everything works.
Sadly, this bad hack will have to be kept around forever and in the
future we will only have more instances of it. I would like to just say
people to fix their system, but apparently this should be worked around
instead.

Previously, the API to set the data that should be displayed was
:set_data(t) where t is a table. This table has the labels to use as its
keys and the numbers as its values. With this API, it was not possible
to influence the order in which the "pie pieces" were drawn.
This commit adds and uses a new API called :set_data_list(t). Here, t is
a table with integer keys and tables as values, thus one can iterate
over this with ipairs() and the order is well-defined. The tables used
as values contain the label as their first entry and the number as their
second entry.

It was currently done all at once. Therefore, the error message was:
CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:415 (message):
A required package was not found
With no further information besides the full dependency list.
With this change, it will print the missing package.
Closes https://github.com/awesomeWM/awesome/pull/1253.
This test has a list of "things" that should be present in the output. This
table is iterated over via pairs(), which means that the output is
non-deterministic and the order of the entries is basically random.
Fix this by using ipairs() to get a deterministic iteration order. This requires
some slight change to the table that is iterated over.

This printed a table. This will make Lua print the address of the table and
hence the output of this test was non-deterministic.

There we go again... When hitting a slow CI node, there is again
timeouts when doing the multi-screen tests. As no solution to
bug leading to this has been found, the only thing to do is
increase the timeout.
Hopefully this commit will be reverted soon.
Spawn callbacks were never invoked when no startup-notification-rules were
given. This commit fixes the code so that "startup done" callbacks are also
called when no rules were given.

This also helps to easier spot failures because of this when looking
at the build matrix.
- Add new check-qa target, to be run only once.
- Add explicit check-unit-coverage target, used with DO_COVERAGE.
This function was iterating over a table with pairs() to generate output (the
sample theme file). Since pairs() does not guarantee any iteration order, this
lead to a different order each time this file was generated. This is, for
example, visible in the diffs in the generate api documentation repository.
Fix this by using a self-made iteration function which behaves like pairs(), but
guarantees an iteration order sorted by keys.

Instead of using Xlib for parsing resource files, this now uses the
dedicated xcb-based library that is meant for exactly this task.

Via this, I can set HEADLESS=1 in my wrapper-GNUMakefile that I use and
"make check" will no longer open a new window that gets in my way.
