[x11] Send app focus loss/gain events

Browse source 
Other subsystems, especially low-level input drivers, need to know when
the app has input focus. eg, as the evdev driver uses the raw stream
from the kernel, which has no idea about X application focus (in fact,
it seems the events are shared across multiple apps without any issue),
the evdev driver sees all the events thus needs to know when to drop
them.
