On Xephyr, when fitst entering x11Window.loop(), syscall.Ppoll would
block forever while XPending() would still return a non zero value.
This commit refactors the loop so that XPending() gets called first,
then fallback to waiting in ppoll if there are no pending draw events.
This has the added benefit of reducing the number of calls to ppoll when
receiving a lot of events.

This driver still lacks fling support and dp/sp configuration.
By default, linux builds will try to use the Wayland driver then
fallback to X11 if it fails. Drivers can be disabled by using either the
nowayland or nox11 build tags.
