* crypto: add support for parsing SSE-C/SSE-S3 metadata This commit adds support for detecting and parsing SSE-C/SSE-S3 object metadata. With the `IsEncrypted` functions it is possible to determine whether an object seems to be encrypted. With the `ParseMetadata` functions it is possible to validate such metadata and extract the SSE-C/SSE-S3 related values. It also fixes some naming issues. * crypto: add functions for creating SSE object metadata This commit adds functions for creating SSE-S3 and SSE-C metadata. It also adds a `CreateMultipartMetadata` for creating multipart metadata. For all functions unit tests are included.
