Apps and system_server are gralloc HAL clients

Test: Play video in YouTube app and in Google Chrome YouTube web page
Test: Using Google Camera app, take an HDR+ photo, a conventional
      photo, record a video with sound and a slow motion video with
      sound, then check that photos look good and videos play back
      fine, including sound.
