- CBC cryptors should accept IV of size 8 bytes - it will be zero
extended to 16 bytes.
- Fixed iv() not updated problem in AesPatternCryptor.
- Replace kChainAcrossCalls with ConstantIvFlag enum flags.

- Create AesCryptor class as the common base
- AesCryptor::Crypt function will serve as an Encrypt function for
encryptor and a Decrypt function for Decryptor.

- Optimize and clean up encryption and decryption code.
- Consolidate various CBC encryption/decryption schemes into a
common class.
- Make it a constructor argument whether cipher block chain is

- Part 1.
- Add packager command line argument "protection_scheme" to specify
protection scheme. Plumb through packager code to enable CBC
encryption/decryption.
- Add scheme type "cbc1" to sinf.
- Refactor AES encryptor and decryptor.
- Need more work in the subsample handling.
