This change adds server-side-encryption support for HEAD, GET and PUT operations. This PR only addresses single-part PUTs and GETs without HTTP ranges. Further this change adds the concept of reserved object metadata which is required to make encrypted objects tamper-proof and provide API compatibility to AWS S3. This PR adds the following reserved metadata entries: - X-Minio-Internal-Server-Side-Encryption-Iv ('guarantees' tamper-proof property) - X-Minio-Internal-Server-Side-Encryption-Kdf (makes Key-MAC computation negotiable in future) - X-Minio-Internal-Server-Side-Encryption-Key-Mac (provides AWS S3 API compatibility) The prefix `X-Minio_Internal` specifies an internal metadata entry which must not send to clients. All client requests containing a metadata key starting with `X-Minio-Internal` must also rejected. This is implemented by a generic-handler. This PR implements SSE-C separated from client-side-encryption (CSE). This cannot decrypt server-side-encrypted objects on the client-side. However, clients can encrypted the same object with CSE and SSE-C. This PR does not address: - SSE-C Copy and Copy part - SSE-C GET with HTTP ranges - SSE-C multipart PUT - SSE-C Gateway Each point must be addressed in a separate PR. Added to vendor dir: - x/crypto/chacha20poly1305 - x/crypto/poly1305 - github.com/minio/sio
