The underlying implementation was not enabling the sensors on a
particular sender even though the Enable signature accepts different
instances of Sender to enable.
Consider the following program:
type A struct{}
func (a A) Send(ev interface{}) {}
type B struct{}
func (b B) Send(ev interface{}) {}
sensor.Enable(A{}, sensor.Gyroscope, time.Millisecond)
sensor.Enable(B{}, sensor.Accelerometer, time.Millisecond)
is going to compile but only A will be notified when there are new
gyroscope and accelerometer events.
In order to improve the misleading APIs, this CL introduces a
Notify function that users can register a Sender implementation to
listen the changes. If set nil, the sensor package will keep
reading the events but will won't notify.
sensor.Notify(A{})
sensor.Enable(sensor.Gyroscope, time.Millisecond)
sensor.Enable(sensor.Accelerometer, time.Millisecond)

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 sensor package had a deadlock case if it started to poll the
events but all sensors have been disabled on the underlying ALooper.
Consider the following program:
app.Main(func(a app.App) {
sensor.Enable(a, sensor.Gyroscope, time.Millisecond)
go func() {
time.Sleep(5 * time.Second)
sensor.Disable(sensor.Gyroscope)
time.Sleep(2 * time.Second)
sensor.Enable(a, sensor.Gyroscope, time.Millisecond)
}()
for e := range a.Events() {
case sensor.Event:
//...
}
The initial Enable will enable the gyroscope and start polling events
from the ALooper. After 5 seconds, the gyroscope will be disabled.
ALooper_pollAll(-1, NULL, &events, NULL)
will block indefinately because there are no events will be
available until another sensor is enabled.
After 2 seconds, we will attempt to enable the gyroscope again. But,
the underlying thread will be blocked at pollAll and won't be able
to make the sensor enabling call on the same thread.
In order to overcome this deadlock case, this thread introduces a
hard timeout limit during polling. If timeout occurs, the looper
thread will be unblocked and select{} statement will be able to
handle {enable,disable,close}Signal cases.

It is an error to use a gl.Context concurrently. (Each Context
contains a state machine, so there is no way this can work.)
Up until now only the GL driver could report such a misuse, and
it generally does a poor job of it. Our command buffer adds some
small oppertunity for the race detector to help, but it makes it
harder to debug other kinds of driver crashes, so it is worth
disabling in debug mode.
To make it easy, compiling with -tags gldebug now inserts an
explicit check that there are no other active GL calls outstanding.
Adding something like:
go func() {
for {
glctx.GetInteger(gl.ALPHA_BITS)
}
}()
to x/mobile/example/basic now reliably crashes when compiled
with -tags gldebug, providing a stack trace that includes both
misbehaving goroutines.

All OpenGL functions are now methods on a Context interface. The
gl.Context matches the one loaded into thread-local storage in C.
For mobile apps, the context is owned by an app.App. For now, it is
provided through the events channel on a lifecycle event. Long-term,
it should probably be available by a method on app.App, but this is
inherently racey with our current use of a channel to deliver events.
Shiny-based programs will have a gl.Context associated with a each
shiny.Window. The expectation is each Window will have different
contexts, allowing them to draw separately.
