Speed up client_ignore_enterleave_events() There are some situations where we do things that can make the mouse pointer enter another window. We do not want to react to these "self inflicted" mouse enter and leave events, because they aren't "real" (= generated by the user). Before this commit, this is done by going through all windows and toggling the "please send us enter and leave events"-bit on them. This becomes slower when many windows are visible and floods the server with requests. This commit changes this to a constant-time logic. Each event contains the sequence number of the last request that the X11 server handled. Thus, we just remember the right sequence numbers and ignore any events that comes in whose sequence number falls into the ignored range. In detail, we keep a list of "begin" and "end" sequence numbers and ignore any enter and leave events that fall in this range. If we get any event with a sequence number higher than "end", we remove this pair from the list, since it is no longer needed. To generate these pairs, we use a GrabServer request in client_ignore_enterleave_events(). This gives us a sequence number and makes sure that nothing else besides us can cause events. The server is ours! In client_restore_enterleave_events(), we first do a NoOperation request to generate the sequence number for the end of the pair and then do UngrabServer. Any event that is generated after UngrabServer will have at least the sequence number of the UngrabServer request and thus no longer fails between begin and end.
