This CL changes the WVDrmPlugin so that an application can segregate its secure stops from those of other applications by setting an application ID. This CL is a merge of the following Widevine CLs: https://widevine-internal-review.googlesource.com/#/c/11565/ Add getSecureStop by ssid https://widevine-internal-review.googlesource.com/#/c/11572 Add getSecureStop by SSID and releaseAllSecureStops by app id. https://widevine-internal-review.googlesource.com/#/c/11564/ Store Usage Info by App Id (device_file stubs) https://widevine-internal-review.googlesource.com/#/c/11563/ Add application id to StoreUsageInfo. https://widevine-internal-review.googlesource.com/#/c/11561/ Added Application ID to PropertySet for secure stop. bug: 18053197 bug: 18076411 Change-Id: I5444baf67ba1b960dee2dc958bced8de82ab70a3
