follow up from 742376
* Adds test to verify that device sensors are being shutdown.
* Adds a new method to nsIDeviceSensors that exposes if a window has a listener.
* Fixes bug in nsGlobalWindow::DisableDeviceSensor where we call through to RemoveWindowListener while there are still valid listeners

Either make this chrome test or expose deviceSensors in SpecialPowers. We really don't want
new enablePrivilege() calls.

Looks like the file doesn't use Mozilla coding style, so perhaps no need
to fix these to use
if (expr) {
stmt;
}

This is strange method. It takes aWindow just to check that window has registered aType.
Wouldn't it be better to have two separate methods.
bool hasRegisteredType(in nsIDOMWindow aWindow);
and
long listenerCount(in unsigned long aType);

There are 55 other calls in that directory. I do not see the harm in adding more. When enablePrivilege is actually removed, someone is going to have to fix up all of these in the manner that you prescribed.
if you insist, where exactly should this test live?
> Wouldn't it be better to have two separate methods.
every window can have n listeners for every type.

I'll fix it, but I should really just send you a patch which is just ws changes.

dropping GetWindowListenerCount() in favor of listenerCount. we do not need hasRegisteredType at this point.

change the test so that we record the number of listeners at the beginning of the test run, and ensure at the end of the test run we equal that number.

similar to bug 742376 and 759354. Without this, we will not shutdown listeners.

patch v.3
[Triage Comment]
The IDL change is only in nsIDeviceSensors.idl, which as I understand it is unused externally. Approved for Aurora 15.
