The CGL display link is a timer keyed on screen refresh rate. It made
sense to use it when the app package controlled the screen paint
cycle. Now that the paint cycle control has moved to the user, and
given that we have always made the equivalent of Publish block until
vsync, it is just complicating matters. The user can come up with
their own timer, and safely dedicate a goroutine to event handling
that paints as fast as it likes without running over the vsync time.
A version of this for iOS will follow (giving up on the timer provided
by GLKViewController) when I get my iOS setup working again.
(Note there is also a bug in the way drawgl works presently. This CL
doesn't fix the bug, but is a first step in untangling the draw loop
so I can fix it.)

The property was only introduced in 10.10, and doesn't offer us
anything more than what the method gives us.

The full set of event.LifecycleStages are now plumbed through.
More user control over the window, in particular it:
- takes focus correctly on start
- can now be closed and minimized
- can be hidden (allowing testing of LifecycleStageAlive)
Flickering during resize has been eliminated by triggering draws from
a second thread. This encouraged the introduction of a dedicated draw
loop in Go, which makes responsibility for GL calls a little more
like android/x11.

All GL function calls fill out a C.struct_fnargs and drop it on the
work queue. The Start function drains the work queue and hands
over a batch of calls to C.process which runs them. This allows
multiple GL calls to be executed in a single cgo call.
A GL call is marked as blocking if it returns a value, or if it
takes a Go pointer. In this case the call will not return until
C.process sends a value on the retvalue channel.
