Back when we were being proactive about merging LMP changes to master in the Widevine repository, there were a few changes that got merged in a different form than what got checked into the Android repository. Mostly, this happened due to several large core changes that were brought over to the master branch in multiple parts so as not to break other teams using the Widevine repository. This patch brings the two trees in sync. Change-Id: I4e56a742686d73d1c6ace209684ce0e8542fd93f
