Replace the vendored version of x/tools/go/loader with the standard
library's go/importer package. This reads the export data from
$GOPATH/pkg/pkgname.a instead of parsing and type checking the source
code. The "go install" subcommand is invoked just prior to reading the
export data to make sure the export data is up to date.
This has the advantage of relying entirely on the go tool for correctly
resolving and parsing dependencies of the package being bound. (For
example, a bound package can now depend on cgo.) It also removes a class
of bugs where the version of the loader we depend on can get out of sync
with the go tool. (For example, gobind now correctly handles vendor
dependencies.)
As a bonus, for packages with significant dependencies this approach
should also be noticeably faster as we do not need to parse and
typecheck all of the dependencies.

Turns out that go install -buildmode=c-shared std does nothing. The go
tool filters all non-main packages from c-shared builds, which for the
standard library is all packages.
This may be a bug in the go tool. I'm not sure yet. But either way, to
make the gomobile tool work with Go 1.5, work around it here.

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.
