[ Merge of http://go/wvgerrit/22980 ] System Renewability Messages (SRM) contains a list of Key Selection Vectors, which are HDCP Identifiers that have been revoked. During HDCP negotiations a transmitter may authenticate a receiver and verify that its unique identier is not present in the SRM. This CL enables reporting of the current SRM version and whether SRM updates are supported. It also loads SRM updates in the license and specifies SRM version requirements when keys are loaded. Test: All unittests other than some oemcrypto, request_license_test passed. Those tests failed with or without this CL. b/28955520 Change-Id: Id840078ea2deb01d9619c1cd8d367b50452f76cc
