[ Merge from Widevine CDM repo of https://widevine-internal-review.googlesource.com/#/c/10171/ and https://widevine-internal-review.googlesource.com/#/c/10172/ ] Updated license_protocol.proto from constituent protos in google3 These changes make use of OEMCrypto v9 changes to support usage reporting. Usage reporting may be enabled for streaming (by means of secure stops) and offline playback by a provider session token specified in the license. Changes include periodically updating usage information for relevant sessions and reporting and releasing usage information as needed. The CDM has removed all references to Secure Stops. This change updates the Android API implementation to comply. b/11987015 Change-Id: Ibb6f2ced4ef20ee349ca1ae6412ce686b2b5d085
