d6c98f1290
(This is a merge of https://widevine-internal-review.googlesource.com/#/c/10141/ from the Widevine CDM repo.) Over the course of revising the CAST support, the need for the MediaDrm to call open and close session was removed. However, the methods to do that were not. This removes the unused code.
