SPOID

Browse Source 
(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.

Bug: 27101531
Test: CE CDM Unit Tests
Test: Linux Jenkins Unit Tests
Test: Android Unit Tests (with and without SPOIDs forced on)
Test: Android GTS Tests
