Initial contribution from Sony Corporation.

  Add DRM Framework to support DRM content playback
  together with StageFright.

  - DRM Framework code is added
     - include/drm
     - drm
  - api/current.xml is updated to include DRM Framework Java APIs
  - cmds/servicemanager/service_manager.c is modified
    to add drmManager and drmIOService.
