[ Cherry-pick of v19 http://go/wvgerrit/219310 ] [ Merge of http://go/wvgerrit/219453 ] To enable the CDM to determine between OEM vs DRM responses, a state variable was needed in CertificateProvisioning. Previously, the presence/absence of the OEM certificate in the file system was used; however, if two apps (or single app with multiple origins) attempts provisioning simultaneously, the later response would trigger unexpected failures. The main functional changes this provides is that a more informative error will be returned to the app if they provide a provisioning response without ever creating a provisioning request; and that if multiple clients attempted first-stage provisioning simultaneously, fewer errors will occur.
