(This is a merge of http://go/wvgerrit/153550.) On CE CDM, storage is split between global and per-origin storage, and one type of storage cannot be used to access the other. (Though, until an upcoming commit lands, the tests will allow it.) On Android, both types of storage access the same filesystem. This means that code may run fine on Android but fail on CE CDM. The OEM Cert in Provisioning 4.0 is a global file that should only exist once, but it was being accessed through the per-origin storage, which would result in a separate OEM Cert being provisioned for each app & origin on CE CDM. This patch changes the Prov 4.0 code to access it through the global storage, using techniques similar to how the Usage Table Header code does this. Test: x86-64 w/ storage separated Test: build_and_run_all_unit_tests.sh Bug: 236400627 Change-Id: I301d250fc9543e62949a4d9fdcbdd109bd941384
