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).

XCB_CURRENT_TIME really should be avoided as much as possible (see
ICCCM).
However, the screen, mousegrabber and keygrabber code have cases where
they really want up-to-date information / want to activate a grab *now*.
These cases are fine with XCB_CURRENT_TIME since they are not related to
some events.

This changes the xembed code so that the caller passes in a timestamp
that should be used instead of XCB_CURRENT_TIME.

This commit changes the systray widget, wibox.drawable and the C code to
fix the following bug: When the systray widget is removed from a
drawable without being moved somewhere else, the systray stayed visible.
This was because the systray is not drawn by awesome, but only placed.
When the widget is no longer "drawn", it stays wherever it was placed
last.
This change works by detecting the situation when the systray is
removed. Then, the C code is specifically told to remove the systray
window from the drawable.
Note that this is only a partial fix. This change works correctly when
the widget is removed completely, because it is no longer placed by its
parent widget. However, for example, when you do
wibox.widget.systray().visible = false, the effect is just that the
systray widget gets size 0x0. This is not really visible, but as far as
this change is concerned, the widget is still part of the drawable.

The XEmbed protocol defines a special property that defines if the embedded
window wants to be visible or not. Up to now, awesome always ignored this entry
and instead behaved as if the bit was set. This commit makes it properly respect
the bit.
Testing done: None. No idea how. Apparently nothing really uses this bit,
because we didn't get bug reports about it yet.

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 }.

The new widget layout code was created because we needed to support partial
redraws (only redraw the parts that were changed). Thanks to this, the code also
skips drawing widgets of size 0x0. Thus, when the systray becomes empty, it's
:draw() callback isn't invoked and thus our systray container window stays
visible.
Fix this by making the C code unconditionally hide the systray when it becomes
empty. There's nothing to display anyway.

The only exception is the window for _NET_SUPPORTING_WM_CHECK. That window
already had a _NET_WM_NAME property before and doesn't get a WM_NAME property in
this commit. I just decided for myself that it doesn't need one. :-)
Right after startup with the default config we now have the following situation:
$ xwininfo -root -tree
xwininfo: Window id: 0x2d7 (the root window) (has no name)
Root window id: 0x2d7 (the root window) (has no name)
Parent window id: 0x0 (none)
7 children:
0x200011 "Awesome drawin": ("awesome" "awesome") 1500x20+0+0 +0+0
0x200010 "Awesome drawin": ("awesome" "awesome") 1x1+0+0 +0+0
0x20000d "Awesome drawin": ("awesome" "awesome") 100x30+0+0 +0+0
0x20000a "Awesome no input window": ("awesome" "awesome") 1x1+-1+-1 +-1+-1

0x200007 "Awesome WM_Sn selection owner window": ("awesome" "awesome") 1x1+-1+-1 +-1+-1
One of those drawin is the awful.wibox. Another drawin is created by awful.menu.
I guess that the third one is created by awful.tooltip, but I'm not sure. Wow,
so many windows...

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 time the systray was updated, we reparented the systray window to its
drawin. However, when the systray was already reparented, this still caused it
to be unmapped and mapped again.
So, we only should reparent the systray when we have to, and not always just for
the lulz.

All windows which use globalconf.default_depth must also have a backpixel,
borderpixel and colormap set when they are created. Without this, all these
xcb_create_window() calls would fail when globalconf.default_depth is no longer

When an X11 client disconnects from the X server, all of its windows are
destroyed. This also means that all the sub-windows of those windows are
destroyed which is not necessary what one wants to happen.
To work around this, X11 has a "save-set". All the windows that are in the
save-set are reparented to their closest ancestor when they would normally be
destroyed. This is just what this code needs. :)
(The windows in the save-set are also mapped when they are saved, dunno if this
hurts here or not)
