56b836bda3
Merge from Widevine repo of http://go/wvgerrit/96783 This CL updates the reference code, unit tests, and adapter to use the new v16 function OEMCrypto_LoadDRMPrivateKey. This is just an API change to allow ECC support in the future. The reference code does not yet support ECC certificates, and the CDM code assumes that all certificates have an RSA key. Bug: 152558018 Test: unit tests on taimen and w/v16 mod mock. Change-Id: I0793b416513b81b3d74849f0b58dbdc91f075ac6
