(This is a merge of go/wvgerrit/23182) This patch adds the framework for Stable Per-Origin Identifiers to the CDM. Calculating SPOIDs will be done on the client-side, and they are sent as part of the provisioning request. SPOIDs are also available to the app as the Device Unique ID, replacing the previous method of returning the actual Device Unique ID from the keybox / OEM certificate. Different SPOIDs must use separate storage, just as different origins already do. Support for this has been added to the Android adapter to the CDM Core. However, the code in the Android glue layer that would drive this behavior will be checked in in a separate change. As such, all Android devices will continue using the legacy behavior even after this patch goes in, until the glue layer code can be updated.
