Could we use a scoped object from src/base/mac/ here (scoped_nsobject?), so that
release doesn't need to be called manually?

[jlebel, 2016/02/10 21:20:08]

I can't include "base/mac/scoped_nsobject.h" because "bluetooth_test_mac.h" is
included by device/bluetooth/bluetooth_gatt_service_unittest.cc:14.
That's why I used "void *" as the type.

Use #if defined(OS_MACOSX) to guard the include as necessary. 

[jlebel, 2016/03/01 21:44:44]

The issue is not OS X vs other platform. The issue is that this file is included
inside c++ files (like bluetooth_gatt_service_unittest.cc), even on OS X.
