Up to now, we always asked the X11 server for color allocation ("which
pixel value corresponds to (r,g,b)?", an AllocCollor request).
This commit adds direct support for TrueColor and DirectColor visuals.
In such a visual, the X11 server gives tells us where the red, green,
and blue color components are in a pixel value and we can then just
directly compute the pixel value.
Additionally, this commit adds code that assumes that in a depth=32
visual, the remaining values (after handling red, green, blue) is the
alpha channel for colors. Thus, this adds support for transparent client
borders.
This commit also touches code for the systray. However, the systray must
always use the X11 server's default visual and that one always(?) has
depth=24, i.e. does not support an alpha channel. Thus, the systray
background still cannot be transparent.
Also, in theory this commit should support visuals where some color
component does not have 8 bits, for example RGB565. However, this is
just theoretic and I have no idea how to actually test this (without
jumping through too many hoops).

I failed to see the obvious. Thanks to mlen from IRC to make
me look into i3's source code so that I can figure out the obvious.
First, what is the problem? We want to be informed about mouse clicks on
client windows, e.g. for client-to-focus. For this we have to grab mouse
buttons on the client window, since only a single client at a time can
ask for information about all mouse clicks (I think...) and that right
is reserved for the actual application and not the WM.
We also want to be informed about mouse clicks on the titlebar, so that
clicking there actually does something (and also e.g. click-to-focus).
Obviously, we can just grab mouse buttons on the titlebar as well.
However, this causes lots of problems. The X11 window containing the
titlebar is not just the size of the titlebar, but also includes all of
the actual client window. This means that clicking into the client also
activates our button grab on the titlebar. This, in turn, causes the
input focus to briefly shift to the window for the titlebar. This shift
of focus can be detected by clients and caused various issues.
This fix is so obvious that I missed it. We don't have to grab buttons
on the titlebar window. We can just use the "normal" event propagation
without grabs there, i.e. we just include the event masks for button
press and button release and get informed about all mouse events. In
fact, we already have this event mask in place, so the whole use of
grabs is redundant.
That's what this commit does. It also partially reverts commit
394ff06589 which is where this unnecessary grabbing was introduced.

Commit 7dad0b3b87 made awesome only ask for mouse events on the actual
client window. Obviously, this means that we no longer get reports for clicks on
the titlebar. Whoops.
Fix this by asking for mouse events on *both* the actual client window and the
frame window. The passive grab on the actual client window is actually unneeded,
but we keep it so that the fix that was done by the above commit is still
present (xev will no longer report leave/enter events just for a mouse click).
Since we now get mouse events inside of a client reported twice, the event
handling code in event.c has to be fixed to handle both cases. E.g. x/y are
relative to the top-left corner of the window and thus needs to be fixed for
titlebar size; the second click has to be ignored.

Since commit 102063dbbd, awesome is a reparenting WM. That means that we put our
own frame windows around child windows. This means that we have the option of
grabbing input events on the frame window or the child window. This commit chose
the frame window for this.
For keyboard events, this decision was already reverted in 532ec0cd90. This
commit does the same thing for mouse events.
This fixes the spurious leave/enter events that were visible on mouse clicks.
They occurred because the click activated a passive grab (all mouse events now
"belonged" to awesome). This passive grab caused the X server to inform clients
that they "lost" the mouse pointer (with the detail field set to "a grab
activated").

Instead of computing the workarea whenever some Lua code asks for it, it is now
remembered explicitly as a property on a screen. This allows us to only emit
property::workarea if the workarea actually changed.

In the case where one want to put the cursor at the middle of the
workarea, it is logic to do:
x=screen.workarea.x+screen.workasrea.width/2
However, this can cause floating points. This commit move the
burden back to the C-API so the Lua placement code doesn't have
to add a large number of rounding methods. Given 1 type of rounding
cover a vast majority of use cases for each types of coordinates,
the C-API can take care of it in peace. For the other corner cases,
it is still possible for the Lua code to do the rounding there, but
no longer necessary. The convenstions are:
'x' and 'y': use round (move to the closest point)
'width' and 'height': use ceil (to avoid involontary truncating)
This change catches things like c:geometry { width = -42 }.

luaA_warn() prints a Lua backtrace and thus generates more useful output. warn()
should only be used in awesome-internal places (e.g. receiving an error from the
X11 server).

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.

This commit makes it possible to add titlebars to a client. These titlebars are
drawables.
The drawin's input handling is moved to the drawable. This allows it to use the
same code for drawin and titlebar input handling, although there are lots of
differences between the two on the C side.
On the lua side, a new wibox.drawable module is created which handles all the
drawable-specific magic and which can also be used for titlebars.

There isn't much point in the screen property of a drawin because the geometry
already defines on which screen the drawin is.
The biggest chunk of changes from this is due to removing the functions
drawin_detach and drawin_attach which where called when the screen property was
set/unset.
The code from drawin_detach is moved into drawin_set_visible and drawin_wipe.
drawin_attach is moved into drawin_init.

Each window is now reparented under a window created by awesome. This window is
NOT visible, this commit should not cause any visible differences. Instead, this
is done to work around problems with X11.
The only alternative would be to ban windows by moving them offscreen which is
ugly in itself and breaks pagers. Doing it like this seems to be the better
solution.
