KongQun Yang 2ac57bf9b9 Use FOURCC as protection scheme parameter
- Remove EncryptionMode enums
- Remove AesEncryptor::InitializeWithRandomIv, replaced with
  a static function AesCryptor::GenerateRandomIv, which should
  be called to generate the iv if the iv is empty.

This change is to prepare support for CBCS and CENS pattern-based
protection schemes.

Bei Li e39c3572af Add support for "AES 128-bit Cipher Block Chaining (CBC-128) Encryption"
- 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.

Jacob Trimble d1d75f477c Add encryption support to WebM.
This does not support key-rotation and will give an error.  This is
because WebM does not have a way to indicate a change in key ID using
media segments.

Jacob Trimble 7b52f0a3ed Added unit tests for WebM Segmenters.
* Changed Segmenters to accept StreamInfo rather than MediaStream
  to help in testing.
* Changed MemoryFile behavior to mirror local file:
  * Read non-existent file is an error.
  * Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.
