xcb: fix various bugs with _NET_WM_MOVERESIZE
1) After a37785ec7638e7485112b87dd7e767881fecc114 it become apparent that we don't get mouse release event from X server when system move/resize ends (because WM is grabbing the pointer). The old code (before a37785ec) would wrongly deduce mouse move as mouse release, which is why the issue was not seen before. The solution is to subscribe to slave device events. 2) This patch also amends 2488f34ecfd68702b5508c50cca3fb8e967ac8ea as that patch was solving the issue only for 1/3 of the supported DEs. It worked with KWin, but not with Unity and Gnome. Its worth noting that it also worked with two other WMs that I tested - openbox and awesomewm. The way forward is to detect when system move/resize was started as a result of touch event and let the QSizeGrip do the move/resize instead of WMs that are known to have bugs. With this patch we also need to adjust the event compression algorithm to not treat all XI_TouchUpdate events equally. For XI_Motion we don't care if the event that we process comes from a master or a slave device, so we can process them as equal.
