This removes reliance on MediaKeys.isTypeSupported and instead uses the supportedConfigurations parameter of requestMediaKeySystemAccess. A lot of refactoring went into this effort, particularly around StreamVideoSource, StreamSetInfo, and StreamInfoProcessor. Closes #2, b/19354928. Change-Id: Ibf81da909b8207b5babaec5ef0422dd1293d130d
