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.

Apparently some versions of dbus kill the process with a failed assertion if
invalid UTF8 should be send out. Mine doesn't. Also, our behaviour of replacing
non-strings silently with strings is weird.
This commit thus makes converting from Lua to dbus fail if a non-string should
be sent as a string or if a string contains malformed UTF8.

The only remaining calls are for a window's opacity and in the DBus type
handling. Everything else wants integers, not something with a comma.

The code doesn't check the type of any of the values that it converts. However,
string elements are silently skipped if they cannot be converted.
The proper fix would be to make this code check types. For now, it will be ok to
"convert" non-strings to an empty string.

The desktop notification specification says that a notification can have
different actions. These actions allow the user to interact with the client
application and should be displayed by the notification server.
* Add function to emit a DBus signal
* Notifications : emit NotificationClosed signal when closing notification
* Notifications: use constant for notification closed reasons
* notifications: Implement notifications actions
This is just a basic implementation to display the actions send with the
notifications. The actions should be displayed differently
* Notifications: add support for default action
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
headers are self-contained. Additionally, this moves some unneeded includes
around.

The port to glib failed to actually watch the file descriptor for events and
thus awesome silently ignored all dbus messages. My bad.

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

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
version exclusively.

This option is no longer valid in modelines, so it has been removed from
all modelines using the following shellscript:
#!/bin/ksh
git ls-tree -r HEAD | cut -f2 | while read f; do
egrep -e '^(//|--) vim: .*encoding=' $f >/dev/null || continue
sed -E -e '/^(\/\/|--) vim:/s/:encoding=utf-8//' $f > /tmp/foo
mv /tmp/foo $f
done

This commit makes it an error if an unknown signal is connected, disconnected or
emitted. All signals have to be added before they can be used.

Before this, awesome_refresh() could be called multiple times per mainloop and
one had to make sure to add awesome_refresh() calls in the right places.
Now, the prepare handler is invoked just before libev puts the process to sleep
(e.g. by calling select()) and awesome_refresh() does its thing.
All redundant calls to awesome_refresh() are removed, but the one in
selection.c has to stay because this function blocks in xcb_wait_for_event()
without using libev.
