When a function is disconnected from a signal ("disconnect_signal") that is not
actually connected to the function, two things happened:
1. The attempt to remove the function from the signal array didn't do anything
2. Unreferencing the function noticed that the function wasn't referenced
The second step printed a big, fat scary warning.
Actually, this has the possibility of causing errors. For example, in the
following code, awesome would wrongly unreference the function at the
disconnect_signal() call and might later still try to call it when the
"refresh" signal is emitted:
do
local function f() end
awesome.connect_signal("refresh", f)
awesome.disconnect_signal("debug::error", f)
end
Fix this by making signal_disconnect() return a boolean value indicating if it
actually did something. All callers are fixed to use this value and only update
the reference counts if something was actually disconnected.

kill is a wrapper around the POSIX kill() function and unix_signal is a table
that maps signal numbers to their names and signal names to their numeric value.

In various conditions, luaA_loadrc() left luaA_dofunction_on_error and an error
message on the Lua stack. Also, it used LUA_MULTRET without looking at the
return values. Fix all of this and reorder the code a bit to make it easier to
follow.

_NET_WM_ICON contains a list of icons and until now, the first one was
picked without regard to it's size. This adds a global option to set
the preferred icon size. When getting the client icon, the best size
match is picked. The size can be set via
awesome.set_preferred_icon_size() and the default is 0, which will pick
the smallest non-zero size icon available.

This patch provides functions to get/set current keyboard layout.
Current implementation doesn't support any configuration of layout,
it's a merely a layout indicator and switcher, however layout
configuration can be set by tools like setxkbmap or by any third-party
tools.
Everything that needs the lua_State should create a local variable like this:
lua_State *L = globalconf_get_lua_State();
This ensures that the compiler warns if there are two variables with name "L" in
scope. The idea here is that it should become harder to accidentally use the
global lua state instead of the state of the current state.
While writing this commit, I found another place that gets its wrong: Reading
client.focus from a coroutine was broken, since it was returning the result on
the main thread instead of the current one.

Every .c file has to include the corresponding .h file first to make sure the

This makes the screen objects use our existing infrastructure for implementing
classes and objects with lua instead of hand-rolling an own version.
This results in some small API change: Screen objects no longer have an
add_signal() function and instead this function exists on the parent screen
class.

Most of these are unused since the drawing code was moved to lua. For example,
the old wibox code needed the metatable entries __next, __ipairs and __pairs so
that w.widgets worked correctly and could pretend to be a regular lua table.

This commits adds awesome.register_xproperty(). This allows lua code to register
arbitrary X11 properties with awesome which will then watch these properties.
Whenever such a property is changed on a client or drawin, we will emit the
xproperty::name signal.
This also adds window:get_xproperty(name) and window:set_xproperty(name, value)
which allows to mess with properties.

We do some special magic so that we can have tracebacks on errors messages.
However, the code for parsing the rc.lua called it without this magic and thus
errors didn't have tracebacks.
This is bad, because if something goes wrong in e.g. wibox.widget.textbox, you
don't really have any clue where this error is coming from.
Fix this by adding our "print traceback on error"-magic here, too.

This commit ports awesome from libev to the glib main loop. This means that
awesome has fewer dependencies, because we were already depending on glib before
and now no longer need glib.
However, the main reason for this change is that, thanks to lgi, we have glib
bindings for lua. This means that lua code can add all kinds of event sources to
the main loop (timeouts, fd watchers, SIGCHLD watchers, ....). Yay

A drawable is something that you can draw to, just like a drawin. However, a
drawable isn't necessarily its own windows. This will later on be used to
implement titlebars where the titlebars are drawables.

The original struct name is luaL_Reg, but Lua v5.1 had a
`typedef luaL_reg luaL_Reg`, which in v5.2 was removed
and as a result breaking the build in Awesome which uses luaL_reg

Now that the C code uses lightuserdata for passing around cairo surfaces, they
are no longer automatically garbage collected. To avoid memleaks, this commit
compares the C code to use cairo_surface_t pointers instead of the lua stack.
This also fixes a memleak were a client's icon was leaked.

If loading of any config file fails, awesome will now remember the error message
and make it available to lua. The default config is modified to open a naughty
popup on errors.
This should help all those people who modify their config and then wonder why
there change is ignored, not noticing awesome's error message on stderr.
