*
* OEMCrypto v16 Core Message Serialization library counterpart (a.k.a. KDO)
*
* For Widevine Modular DRM, there are six message types between a server and
* a client device: license request and response, provisioning request and
* response, and renewal request and response.
*
* In OEMCrypto v15 and earlier, messages from the server were parsed by the
* CDM layer above OEMCrypto; the CDM in turn gave OEMCrypto a collection of
* pointers to protected data within the message. However, the pointers
* themselves were not signed by the server.
*
* Starting from OEMCrypto v16, all fields used by OEMCrypto in each of these
* messages have been identified in the document "Widevine Core Message
* Serialization". These fields are called the core of the message. Core
* message fields are (de)serialized using the ODK, a C library provided by
* Widevine. OEMCrypto will parse and verify the core of the message with
* help from the ODK.
*
* The KDO library is the counterpart of ODK used in the CDM & Widevine
* servers. For each message type generated by the ODK, KDO provides a
* corresponding parser. For each message type to be parsed by the ODK,
* KDO provides a corresponding writer.
*
* Table: ODK vs KDO (s: serialize; d: deserialize)
