Make the easyx library in the extras distribution compile again.

Rename the event/0 type to x_event/0 in order to avoid conflicting
with the event keyword used in event goals.

Fixed a latency bug in the easyx interface. One has to tell the
Xlib XSync function to discard any pending events in the input queue
in order to avoid noticable event processing lag in applications with a high
refresh rate.
easyx.m:
Moved the import of xlib to the implementation section (xlib is
not used in the interface.)
Added easyx.sync/3.
xlib.m:
Changed xlib.sync/1 to discard any events waiting in the input queue.
samples/bounce.m:
Now uses easyx.sync/3 rather than easyx.flush/3, which dramatically
improves responsiveness.
