We no longer have to turn the client's content into an image buffer "by hand".
Instead, we can just use cairo for the job.
Even more exciting, we don't need to turn this into an image buffer at all. We
can just directly return a cairo xcb surface for the client window. Depending on
how lua will use this surface, this could make it possible to avoid having to
create the image buffer at all!

The size saved in c->geometry also includes the titlebars. Thus, for getting the
window content, we have to subtract this from the size.
Before this, the call to xcb_image_get() was failing with a BadMatch error,
because we were asking for an area that is outside of the actual client's
window's geometry.

I noticed high CPU usage while using asunder. The reason was that asunder
re-sets its window name every 0.1 seconds (and awesome's drawing code is way too
slow).
A semi-fix for this is to ignore string property changes if the old and new
value for the property are equal.

When property::surface is emitted, the drawable didn't know its geometry yet,
which had weird side effects. Fix this by changing the C API a little. The
function drawable_set_surface() now no longer allows a NULL surface as its
argument.
The required changes for the titlebar code also means that we no longer throw
away the double-buffering surface when a client is moved.

The code assumed that a window gets resized when it enters/leaves the fullscreen
mode. This was needed because the code for resizing a window hides and shows the
titlebars.
However, it is possible for a window to enter/leave fullscreen mode without
getting resized, because it already has the correct geometry. In this case,
titlebars were not handled correctly.
This commit fixes that by forcing a resize to the current geometry when the
fullscreen flag is toggled.

Fullscreen clients shouldn't be decorated, thus hide titlebars on those.

The code was sending out ConfigureNotify events which contained the size of the

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.

When something gives the input focus to the client which already has the input
focus, bad things can happen. Normally, you'd expect nothing to happen in this
case, but X11 is not that simple.
When updating the input focus and the focused client has the nofocus hint set,
we are actually taking away the focus from this client.
Hopefully this fixes FS#973.

Previously, when we received a FocusIn event, we would update the input focus,
because client_focus_update set globalconf.focus.need_update to true.
However, this is wrong for clients following the globally active focus model,
because in this case its the client which controls which window has the input
focus. It could happen that we thus took away the focus from the client which
just gave itself the focus.

Lua code can give the input focus to unfocusable clients. That means they have

This moves the loading of the rc.lua and managing of pre-existing clients to
after we ungrab the server during startup. To make sure we have no races with
clients which start up parallel to awesome, we do the QueryTree for all the
clients that we have to manage before the ungrab, but start managing the clients
only after the ungrab.
This means that we have already selected our event mask on the root window in
scan() and thus received an UnmapNotify event when we reparent windows into a
frame window. This has the effect that we immediately unmanage the client again,
whoops.
To fix this, we grab the server again and remove our event mask on the root
window again while we reparent.
This should hopefully fix all cases where we deadlock during startup because
pulseaudio wants to talk to the X server, but is being ignored because we have
the server grabbed while at the same time we are waiting for pulseaudio.

When a client sets WM_NAME (client->alt_name) but doesn't set _NET_WM_NAME

In commit 3dbf89c I removed a client_unban() in the code path for focusing

However, minimized clients obviously don't get unbanned, So we have to call
client_unban() here to make sure the client is unminimized.

Previously, if a client had nofocus == true, it wasn't unminimized if sth tried

When one sets a client to fullscreen, this is what currently happens:
- lua code: c.fullscreen = true
- The C code emits request::fullscreen without having touched the client's
fullscreen property yet (c.fullscreen is still false)
- awful.ewmh changes the client's geometry to fullscreen via c:geometry()
- This causes property::geometry to be emitted
- awful.layout reacts on this and causes the screen to be re-arranged, undoing
the fullscreen geometry set in awful.ewmh
- The C code for c.fullscreen = true continues and actually changes the client's
fullscreen flag
The result of this is that we get a client which thinks it is fullscreen'd
without actually being that.
Fix this by first changing the client's fullscreen property and then emitting
request::fullscreen. Same thing for maximized_{vertical,horizontal}.
