Implements the optional setMediaDrmSession() method. To enble this, support was added to the core to report if a session ID is valid. As a consequence of this, in the tests for the CryptoPlugin, construction of the plugin must be deferred until all gMock expectations are set, as construction now calls into the CDM core. This is a merge of two changes from the Widevine CDM repo: http://go/wvgerrit/14083 Allow Setting of Session ID http://go/wvgerrit/14085 Check If Session ID Is Valid When Changing CryptoPlugin IDs Bug: 19570317 Change-Id: I7dbd777ce6efebd71fdb5e602663a0e35a48a9c4
