Xlib uses unsigned long for XIDs, but xcb always uses uint32_t. Thus,
this needs the format string for uint32_t now.

IANAL, but I think I am allowed to add missing copyright notices for
someone else. And I did my best job using git history to figure out who
wrote which functions. So I hope everything is fine.
Bugs:
* There seems to be a noticeable frame loss when window
is being opened/closed. But the same problem also exists
in master/next, so this is not a regression.
* Using --sw-opti and --benchmark at the same time causing
compton to draw more frequently than permitted by the
arguments. That is because the sleep interval calculation
is flawed. Not really a regression either.
Verified still working:
* Usual painting
* Fade
* Benchmark mode
* --sw-opti (with or without benchmark mode)
* DBus
* Unredir delay

Re-did the painting logic, and document it.
It is unclear to me what is the previous painting logic. But the current
one is basically this:
1. Go through all windows top to bottom, and put visible windows (not
unmapped, opacity > 0, etc) into a linked list, from bottom to top
2. Accumulate a region of ignore on each window, which is basically the
region of screen that is obscured by all the windows above current
one.
3. Paint all the visible windows from bottom to top. Subtract the region
of ignore from the painting region. If we need to paint shadow, we
subtract the body of the window from the shadow painting region too,
because we don't want shadow behind the window.
4. region of ignore is invalidated when window stack change, an
window on top moved or changed shape, when window changed between
opaque and transparent, etc.
Notes:
It is unclear whether all the different shapes of a window (extents,
noframe, border, bounding shape, etc) are calculated correctly or not.
It is unclear if window shape related events are handled correctly or
not. Need more testing.

Change `win *` to `win **`, because a window could be freed by the
callback, so we can set `*w` to NULL to communicate that.

Also remove some debug function calls (there are better tools for opengl
debugging now). Also remove copysubbuffermesa
