[ Merge of http://go/wvgerrit/102109 ]
The CDM was using unique CDM error codes for the various cases
where OEMCrypto would return INSUFFICIENT_RESOURCE. However, these
error codes were being incorrectly mapped at the Android level,
resulting in incorrect errors in the MediaDRM layer.
At no point does the CDM handle different INSUFFICIENT_RESOURCE_x
within the same case, as such the use of unique codes are limited.
This CL removes the unique codes, and unifies them under the same
CDM error code.
This CL also extends SelectKey to handle error codes returned by
LoadEntitledContentKeys.
