Merge from Widevine repo of http://go/wvgerrit/122223
This adds the ODK unit tests to the CE CDM tests so that they run as
part of the presubmit tests.
The test helper had some pointer problems converting a bool to a
uint32, so it has been updated to handle this correctly.
Some other tests failed comparing signed to unsigned, to these have
also been fixed.
test: ran odk_test
