We are getting a lot of noise from Android bug-filers who are
concerned about several non-critical errors that show up when using
Widevine CDM on some devices or in some use cases. To mitigate this,
we are downgrading these errors to warnings.
Some of these errors pertained to our legacy support. To make sure
an error IS logged if problems with legacy support become critical,
a new error has been added to that code path.
