[AWARE] VTS baseline

Modified Wi-Fi test setup/tear-down to shutdown and start the
Android framework. The framework competes with the VTS to control
the HAL and so must be disabled for the duration of the test.

Added framework to support VTS testing with the Wi-Fi Aware (NAN)
interface.

Added all callback types (notifications, events) with ability to
wait for such callbacks.
