--dbe does not seem to have an effect on tearing, as noted in the old
manpage, and confirmed by my own testing.
So remove it, since it complicates the logic of painting.

This way we don't need to update the bounding region after window moves.
Also add some comments about the coordinate systems in compton.
Also change a few function that takes a `bool global` parameter to
always return region in local coordinates.
win_rounded_corners is called by win_updated_bounding_shape, so there is
no need for the former to call the later.

With libX11, the library calls an I/O error handler if the connection to
the server breaks. The default I/O error handler prints an error message
and calls exit(). This can be seen when running a "pre-xcb" compton
against Xephyr and then closing the Xephyr window:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":1"
after 241 requests (241 known processed) with 0 events remaining.
The current compton would just continue running. After this commit, it
instead exits with this message:
handle_queued_x_events(): X11 server connection broke (error 1)

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
