This is a merge from the widevine repository of http://go/wvgerrit/13923 Switch openssl to use the EVP interface for aes-ctr-128 http://go/wvgerrit/13979 Add Test Certificate to OEMCrypto Mock http://go/wvgerrit/13978 Add Test Keybox to Level 3 OEMCrypto http://go/wvgerrit/13873 Enable OEMCrypto Unit Tests This CL adds a main program to oemcrypto_test.cpp, which filters out tests that are not supported on the specified platform. It also adds LoadTestKeybox to the mock. This allows oemcrypto unit tests to be run on devices that have production keybox. It also allows the same set of unit tests to work on Android and on non-Android platforms. b/18962381 Use test certificate (partial fix) b/19867990 Separate cast receiver tests Change-Id: If89c31530103ed85aa37d7379bd5b4dc2a927f38
