Bei Li 9ddf9276ce MPD signaling for Dolby Enhanced AC3 audio.
Parse channel layout value from dec3 box. Pass it through audio stream
info. MPD builder forms audio channel configuration to signal ec-3
codec.
Specs: 1) ETSI TS 102 366 V1.3.1 Digital Audio Compression (AC-3,
Enhanced AC-3) Standard E.1.3.1.8.
2) DASH-IF Interoperability Points v3.0 9.2.1.2.

Jacob Trimble cd74066bb4 Outputs default_KID for non-MP4 ContentProtection elements.
Now outputs cenc:default_KID attributes on all ContentProtection
elements for non-MP4 streams.  For MP4 streams, it will still output
the default ContentProtection element.

Closes #69

Rintaro Kuroiwa 5ad076d92c Fix schematron validation problem for live
- From DASH spec 2014, MPD@publishTime and Period@id are required for
  'dynamic' MPD.
- Period@id is always set to "0".
- MPD@publishTime is set to the time when the MPD is output.

  locks, removing locks from MpdBuilder.

Rintaro Kuroiwa 749571fc07 Do MpdBuilder test TODOs
- Added factory methods for creating Representation and AdaptationSet in
  tests.
- Since most tests only needed access to the constructors for
  Representation and AdaptationSet, instead of using
  FRIEND_TEST_ALL_PREFIXES() for each test case, added factory methods
  on the test class.
- Check the 'frameRate' attribute in
  CommonMpbBuilderTest.SetSampleDuration.

Rintaro Kuroiwa 76e5be3756 More fix for live
- Neither live with or without key rotation did not output the right
  result.
- No key rotation: did not produce any ContentProtection element.
- With key rotation: did not have DRM specific ContentProtection.
- To get key rotation working with shaka player, <cenc:pssh> elements
  are removed.

- MpdWriter uses MpdNotifier now, instead of directly using MpdBuiler.
- Add mock_mpd_notifier.{h,cc} to be shared by several tests.

  ContentProtectionElements. The logic is moved from MuxerListener.

  ContentProtectionElement.

language tag when there are multiple possibilities.
