rclone / gofakes3

A simple fake AWS S3 object storage

This is a fork of johannesboyne/gofakes3 mainly for use implementing the rclone serves3 command in rclone/rclone.

Notable differences:

• Use modified xml library to handle more control chars
• Func getVersioningConfiguration will return empty when unversioned
• New func in backend interface: CopyObject
• Support authentication with AWS Signature V4
• Interfaces changed to take context
