Referer policy strict-origin and strict-origin-when-cross-origin changes have been implemented. Relevant unit test cases have been added. Enum for RefererPolicy has been added to hyper codebase and v 0.9.11 of hyper contains these changes.
This commit also contains changes related to upgrade of hyper from v0.9.10 to v0.9.11. Other dependencies changed are rayon, utils, num_cpus.
This commit adds new files related to implementing the [Request
API](https://fetch.spec.whatwg.org/#request-class). This commit also
changes the expected web platform tests results. It also modifies the
following files:
components/net_traits/request.rs
HeapSizeOf is implemented in net_traits/request so that dom::request can
be used as a wrapper around net_traits::request::Request.
components/script/dom/headers.rs
Several methods are added to Headers so that request can access and
modify some of the headers fields.
