Currently headers are exported at many places. For example you can access `Transfer-Encoding` header at `header`, `header::common` and `header::common::transfer_encoding`. Per discussion on IRC with @seanmonstar and @reem, all contents of headers will be exposed at `header` directly. Parsing utilities will be exposed at `header::parsing`. Header macros can now be used from other crates. This breaks much code using headers. It should use everything it needs directly from `header::`, encodings are exposed at `header::Encoding::`, connection options are exposed at `header::ConnectionOption`.
