libhardware_legacy: Add support for oneshot WiFi setup

 * For a certain device, we need to wait for the RIL to dump out
   the NV items which contain the WiFi MAC address. This is
   done by starting a service and waiting for it to set a property
   indicating completion. The existing module loader already works
   like this, so we can just use that.
 * Reorder the ifdefs so this works when the driver is not built
   as a module.

audio: Disable sonification on digital USB outputs

 * We don't want to hear touch sounds on our badass USB DACs. Just
   play the damn music, please :)

audio: fix offload enabling test parameter

passing NULL as the default to property_get doesn't return false,
it returns random memory junk that evaluates to true... Explicitly
default the state of this property to "false" as a default

audio: fix for multi-channel HDMI playback

- Overwrite playback flag to AUDIO_OUTPUT_FLAG_DIRECT
  for PCM_16_BIT multi-channel clips so that HDMI
  profile is used for playback.

AudioPolicyManagerBase : MUTE_TIME_MS reduced to 500ms

 - Some streams are muted while the audio path
   is switched for different device switch like
   BT, Headset, AOS and HDMI etc. Audio drop is
   observed for more than 3-4 secs. So tuning
   this macro for better results.
