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.

Uli Schlachter 3ed73b1f8e Replace last definitions from Xcomposite.h with xcb
Note that this adds an include for Xfixes.h, because that header is
still needed and was previously included through Xcomposite.h.

Uli Schlachter 7719dc7325 RENDER: Fix check for convolution filter
The X11 server's answer is not \0-terminated, so xcb_str_name() also
does not provide a \0-terminated pointer.

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.

Yuxuan Shui 72231098d1 Refactoring
* Move code around
* Remove unneeded forward declaration
* Rename win->damaged to win->ever_damaged, to be less confusing
* Expose debug functions even when DEBUG is not enabled. Compiler
  would remove the dead code for us anyway.
* Some code cleanup
