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.

Yuxuan Shui 2a4fed50f4 Use libev for inputs and timeouts
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

Yuxuan Shui 28a2cc62fa Convert XfixesRegion to pixman region
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.

Uli Schlachter 00ae9718ee Handle asyncronous X11 errors
Errors for requests sent via Xlib that expect a reply are handled via
XSetErrorHandler(), which sets up a callback function that Xlib calls.
Errors for requests that do not expect a reply or for errors caused via
unchecked XCB requests show up as events of type 0 in the event handling
function.

Before this commit, errors were ignored here. This commit changes the
code so that the errors are printed instead.

Yuxuan Shui 7af815a0aa Proper fix for screen freeze
If an X event is received at a very specific point in time, it can trigger
a race condition in Xlib. Said event will be read, but Xlib will
nonetheless be completely unaware of the event.

This cause compton to sometimes block on select() while there are events
ready to be processed. If the event is a damage report, screen freeze
will happen until some other event is received.

The proper fix is to switch to xcb for event handling, thus avoid this
problem entirely.

Yuxuan Shui 967d9f32ea Workaround for what seems to be a race in Xserver
There seems to be a race between DamageAdd (what the client uses
to report damage to Xserver) and DamageSubtract (what compton uses
to clear the reported damage, so it can receive new ones). I am not
sure how to confirm this. But this (terrible) workaround seems to
solve this problem.

Uli Schlachter f8ea3e8668 Don't steal the _NET_WM_CM_Sn selection (#301)
Before becoming the selection owner for _NET_WM_CM_Sn, compton will now check if
that selection is already owned (which means that another composite manager is
already running). If this check fails, startup will be refused. This behaviour
is required by EWMH / ICCCM.

Because this should catch all composite managers, the error message that was
used before when another manager is already running is reworded to mention that
the other manager does not follow EWMH.

Yuxuan Shui cfdb946992 Avoid using window id as identifier in finish_destroy_win
Under extreme race conditions (window A close at the same time as window
B create), there can be multiple windows with same id in compton's window
list. If at this point window B closes itself as well, finish_destroy_win
might destroy a different window as what's passed to destroy_callback.

This can be a problem because someone can still hold a reference to that
window (e.g. 't' in paint_preprocess), and there's no way to clear that
reference. If finish_destroy_win always destroy the same window passed
to destroy_callback, this will not be a problem.

Bug fix: Select the larger of the X window border width and
_NET_FRAME_EXTENTS, instead of adding them together, when determining
the frame extents. (Supposedly) more EWMH compliant, as EWMH
_NET_FRAME_EXTENTS should include the X window border width already. We
did not choose to completely rely on _NET_FRAME_EXTENTS to remove the
need to keep track of whether there is a _NET_FRAME_EXTENTS, and
(hopefully) take care of some cases when it is wrong. The commit should
fix awesomeWM/awesome#425. Thanks to psychon for the information. (#302)

The commit fixes the bug in win_get_region_noframe() that the X window
border width is not considered when determining the width/height of the
window without frame, as well.
