Framework: Ensure Intent.ACTION_USER_PRESENT Is Sent

If the user set a keyguard delay (AOSP-Secure-Delay)
	and the screen turned off, many processes will
	thus assume the user is no longer present (true).
	If the screen is turned on before the keyguard
	enables itself, the USER_PRESENT broadcast is never
	sent and the app/process will not know the user has
	returned to using their device.

AudioService: fix safe volume enforced even when disabled

On onConfigureSafeVolume, the proper API was not used, leading
to the setting not being respected. Sometimes after boot, the
heaadset volume will be set back to the safe volume.
