Vlad Zahorodnii a433fb08a3 x11: Make removal of X11 event filters safe 
If an X11 event filter has been activated and it unregisters another X11
event filter, then the window manager may crash because the foreach macro
in Workspace::workspaceEvent() makes a copy of m_genericEventFilters or
m_eventFilters and we can call the event() method for an already defunct
filter.

With this change, X11 event filters can be safely removed and installed
at any particular moment.

* @code
* xcb_window_t w; // our test window
* X11Client *client = findClient([w](const X11Client *c) -> bool {

* @code
* xcb_window_t w; // our test window
* X11Client *client = findClient(Predicate::WindowMatch, w);
