It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

This makes it possible to add something similar to a __index / __newindex
metamethod to all our C objects. Based on this, Lua can then easily implement
arbitrary properties on our capi objects.
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))

Every .c file has to include the corresponding .h file first to make sure the
headers are self-contained. Additionally, this moves some unneeded includes
around.

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.

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.

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.

This new property is used for fixing some missing redraws that the old code had.
Those could be seen via awful.menu. Open and close a submenu repeatedly and the
submenu will appear black.

A drawable is something that you can draw to, just like a drawin. However, a
drawable isn't necessarily its own windows. This will later on be used to
implement titlebars where the titlebars are drawables.
