This CL updates documentation, reference code, and unit tests to match the OEMCrypto v15.1 API. 1. The design for the Full Decrypt Path Testing application has changed. Instead of reading hashes from an external file, it will use a single key frame and modify it to match the desired size. The test application will then compute the hash and encrypt the frame. For OEMCrypto, this means that there will not be a call to OEMCrypto_InitializeDecryptHash before the frame and OEMCrypto_SetDecryptHash after the frame. Instead, there will be a single call to OEMCrypto_SetDecryptHash before the frame. The function OEMCrypto_InitializeDecryptHash will not be used. 2. The "Shared License" feature is not used by any production server. This functionality is no longer required and OEMCrypto may reject licenses with a nonzero bit 23 in the key control block.
