The documentation for awesome.register_xproperty, awesome.get_xproperty
and awesome.set_xproperty were lost in commit 26f15a13f3. This

Up to now we assumed that the default config is in a path where
xdgConfigFind() finds it. However, evidently this is not always the
case, so make this explicitly try the default configuration file.

Before this, there was a function which attempted to load different
configuration files in the right order. There was a boolean argument
that decided if we are actually loading it or just checking for syntax
error (for the --check argument of awesome). This lead to some
not-so-nice code since we do not want to fall-back to another config
when checking for syntax errors.
Refactor this so that there is now a function which calls a callback
function with the different paths that should be tried. This function
returns as soon as the callback function returns true.
Since just checking if the config syntax is ok does not depend on any
Lua state, an empty Lua state is now used for this.

It makes more sense to append the xdg config dirs to our list of
searchpath in awesome.c than in luaa.c. Plus, it simplifies some of the
following work.

* Refactor modification of package.path
Awesome adds various entries to package.path during startup. This commit
moves that into a helper function. No functional changes intended. The
only change I did to the code was changing a call to lua_type(L, 2) into
lua_type(L, -1);.

This function should only be necessary for the test suite. It makes sure
that the X11 server received and handled all previous requests that
awesome sent. This will be needed, for example, in tests that use
root.fake_input().
After a call to awesome.sync(), we are sure that "faking input" has been
done and the next main loop iteration will handle the input event.
Without the sync, it could happen that the X11 server did not yet fake
the input in the next iteration.

Add a single "do" to the beginning of the config. This causes a parsing
error ("'end' expected") and then another warning saying "something was
left on the Lua stack.
Fix this by popping the error message where we need to do so.

The same effect could be achieved by modifying $LUA_PATH or with symlinks, but
having a special option to do this seems easier.

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.

In various conditions, luaA_loadrc() left luaA_dofunction_on_error and an error

_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.

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.
