At the beginning of every main loop iteration, we check for new events
from the X11 server. However, it's theoretically possible that during a
main loop iteration new events arrive and are read by libxcb into its
internal buffer. This would mean that the fd connected to the X11 server
is not readable and thus we do not wake up to handle these events.
Handle this by checking for pending events before calling poll(). If a
new events appears, we set the timeout for poll() to zero and will then
handle the new event in the following iteration of the main loop.

Daniel sees a short flicker of his wallpaper when he closes a client.
This happens because the window is destroyed immediately, but other
clients are re-arranged only shortly later. In the mean time, the X
server updates the display and repaints the root window (= wallpaper
becomes visible).
Work around this by delaying the destruction of frame windows to the end
of the current main loop iteration. This means that we first update the
position of all other windows and later destroy the window that was
actually closed.

There are some situations where we do things that can make the mouse pointer
enter another window. We do not want to react to these "self inflicted" mouse
enter and leave events, because they aren't "real" (= generated by the user).
Before this commit, this is done by going through all windows and toggling the
"please send us enter and leave events"-bit on them. This becomes slower when
many windows are visible and floods the server with requests.
This commit changes this to a constant-time logic. Each event contains the
sequence number of the last request that the X11 server handled. Thus, we just
remember the right sequence numbers and ignore any events that comes in whose
sequence number falls into the ignored range.
In detail, we keep a list of "begin" and "end" sequence numbers and ignore any
enter and leave events that fall in this range. If we get any event with a
sequence number higher than "end", we remove this pair from the list, since it
is no longer needed.
To generate these pairs, we use a GrabServer request in
client_ignore_enterleave_events(). This gives us a sequence number and makes
sure that nothing else besides us can cause events. The server is ours! In
client_restore_enterleave_events(), we first do a NoOperation request to
generate the sequence number for the end of the pair and then do UngrabServer.
Any event that is generated after UngrabServer will have at least the sequence
number of the UngrabServer request and thus no longer fails between begin and
end.

This commit adds a "removed" signal to screens. Together with the "added" signal
that we have since a while, this allows the C code to update the list of
available screens dynamically without needing to restart.
So far, this code received only minimal testing. So far, I don't have a nice
idea on how to easily test this...

This function needs the event numbers for events from some extensions. These are
assigned dynamically by the server. Right now, this is done by having a bunch of
static variables that are initialized when needed.
Refactor this to have a function event_init() instead that sets variable in
globalconf (where all of our state should be saved). Also, a preprocessor macro
is introduced to handle event dispatch which also looks a bit nicer.

_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.

Whenever client.focus == nil, we set the input focus to the root window to
express "nothing has the input focus". However, thanks to the way X11 input
works, this means that whatever is under the mouse cursor gets keyboard input
events. This can easily be reproduced with urxvt and some small addition to the
config to unfocus things.
This commit changes things. Instead of focusing the root window, we create a
special "no focus" window that gets focused if we want nothing to have the
focus.

This adds a global variable that tracks the drawable that is currently under the
mouse cursor. This new variable is then used so that we get consistent behavior
for enter/leave signals. Such signals are now also generated when a MotionNotify
event tells us that the pointer is now in a different titlebar.
Before this, it was possible that we did not generate a leave event on a
titlebar since the LeaveNotify contains the cursor position after the leave and
we did not manage to figure out which titlebar was left.

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.

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.

A drawin's and a client's bounding and clip shape can now be queried and is
returned as a cairo surface. Also, a client window's shape (e.g. xeyes setting
its own shape) can be queried via c.shape_client_bounding and
c.shape_client_clip. All of these properties now emit signals when changed.
(This also silently fixes a bug in luaA_drawin_set_shape_bounding() which forgot
to include the drawin's border in its size calculation)

Thanks to Michael Stapelberg, there is now a xcb-only port of libXcursor which
does everything we need. This patch switches awesome over to that new library.
Since the only reason for using XOpenDisplay() instead of xcb_connect() was so
that we can use libXcursor, we can get back to that older state again. This
means that this effectively reverts the following commits:
531f8b415c "Added initial support for Xlib cursor themes"
77243cd09a "Add x11-xcb to the pkg-config checks"
779d43fc46 "Don't let Xlib own the event queue"

This reverts commit bd8158495e.
The idea was to track the current list of pressed and depressed mouse buttons,
because we get button events for more than 5 buttons, but can only query the
state of the first 5 buttons.
However, there are cases where we see button presses, but won't see the
corresponding release event. This is quite 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
