Merge from Widevine repo of http://go/wvgerrit/24728 We use compiler options to set different properties in the oemcrypto mock. With this CL, we define a base class that has default properties. All other variants need only define the properties that they change. b/35141278 b/37353534 Change-Id: Id38ec5bf35dcd83cea9a066ebe201e6da7c1a2b0
