This just pushed the drawin onto the stack L, but then tries to access it via
globalconf.L. This just calls for problems...

A stack index without the corresponding lua_State pointer is useless, because it
could reference another coroutine than the main thread and thus just assuming
globalconf.L is wrong. Fix this by also passing around the corresponding
lua_State pointer.
This improves the result for the following test:
coroutine.resume(coroutine.create(function()
drawin({}).visible = true
end))

This fixes the following code:
local d = drawin({})
d.visible = true
The drawin now has a cairo surface assigned
d.visible = false
d.width = 1234
d.visible = true
The width change while the drawin was not visible would not get propagated to
the drawable because of the code that this patch removes. The expectation was
that drawin_map() would update the drawable later.
However, because the drawin was already visible, its drawable also already has
a surface assigned. Thus, drawin_map() wouldn't update the drawable either.
Fix this by just removing this optimizations.

The code in drawin_moveresize() tries to be clever and only updates the drawing
state of the drawable when it is resized, not when it is moved around. This used
to be necessary because once upon a time, drawin_update_drawing() threw away all
of the drawing state and thus forcing a repaint. These days it just calls
drawable_set_geometry() as well and that function special-cases moves.
So this old code in drawin_moveresize() is no longer necessary and actually
caused problems.
These problems occurred because drawin_update_drawing() is being clever and
doesn't do anything for .visible = false drawins, because their drawing state
will be updated once they become visible. However, not skipping
drawable_set_geometry() means that this broke, because drawin_map() thought that
the drawing state was up to date while in reality it wasn't.

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.

The X11 server tells us about things that need to be redrawn via expose events.
When we get such an expose event before lua drew the drawable, we just fill the
exposed area with old data (which is black for newly-created drawables).
Fix this by tracking if we have any usable data in a drawable's double buffering
pixmap. This flag is unset whenever we throw away the old content (e.g. due to a
resize) and is set when lua gave us some new content to display.
Signed-off-by: Uli Schlachter <psychon@znc.in>
Previously, ownership of the pixmaps that we are using for double buffering was
a little weird. The pixmap belonged to the drawin/titlebar, but the
corresponding cairo surface was owned by the drawable. Clean this up by moving
the pixmap to the drawable.
This cleans up lots of ugly code and also fixes a crash: When a drawable was
garbage collected before its drawin, drawin_wipe() would crash accessing the
drawable. This was needed to make it forget about the cairo surface we gave to
it for the pixmap that is being destroyed.
By moving the pixmap to the drawable, this whole issues goes away.

Before this commit, we always threw away the drawin's cairo surface whenever it
was made visible and thus forced a redraw.
This commit changes this so that we only force a redraw if the drawin was
resized why it wasn't visible. To remember when this happens, we free the
drawin's cairo surface without allocating a new one when the drawin is resized
while not being visible. Thus, we then only have to allocate a new surface if
the drawin doesn't have one when it is being made visible.

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"

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.

We only need to update a drawin's drawing related resources when its size
changes. Thus, when a drawin is just moved, drawin_update_drawing() is not
called. However, this function was used for telling the drawin's drawable about
its geometry. This means that the drawable had an outdated idea about what its
geometry was.
Fix this by making sure to always call drawable_set_geometry().

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.

We were only creating an X11 window for a new drawin after we handled all the
options that were passed in. However, this means that drawin({ height = 4 })
would try to resize the window before we created a window, which caused an X11

Fix this by moving our initialization before of the handling of construction

Open some windows, select a layout which does something (=not floating) and
restart awesome. It's likely that it will crash during the shutdown.
The reason is that awesome cleans up various state before going down. This is
mostly all the lua state. However, drawin_wipe, which is called for cleaning up
after a drawin, dared to emit a sigal which then let various lua code run which
had access to objects which were already destroyed.
Various bad things can happen this way, in this situation it was a crash when an
already-destroyed client was resized.
The fix is to move the signal out of drawin_wipe. It doesn't belong there
anyway. Instead, property::workarea should be emitted when the drawin's visible
property changes as this is when the workarea changes, too (screen_area_get()
only looks at visible drawins).

This fixes a crash when the opacity of a not-visible drawin is changed. This
happened because we got a PropertyNotify for our own change of _NET_WM_OPACITY
and then tried to set the drawin's opacity to this new value.
However, the drawin was only reachable through globalconf.drawins and wasn't
ref'd in lua. This means that the luaA_object_push() call in
property_handle_net_wm_opacity() didn't find the drawin and instead pushed a
nil. This then later caused an unprotected lua error in window_set_opacity().

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.

Instead of creating/destroying a window whenever the drawin is attached/detached
from some screen, a window is now created when the drawin is created and it

this should make it possible to simplify some stuff.
