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.

KongQun Yang 0218d9c690 Move fourccs.h and rcheck.h to media/base
- FOURCC is not a mp4 only concept. It is also used elsewhere.
- RCHECK has been used outside formats/mp4.

Also updated the FOURCC enum names to match the actual fourcc code, e.g.
FOURCC_mdat for "mdat".
