We are going to infer all RequestContext types from the corresponding
nsContentPolicyType. It no longer makes sense to store both of these on
InternalRequest. This has the extra benefit that we don't need to worry
about keeping them in sync any more.
As the documentation in InternalRequest.h in this patch shows, the
mapping between nsContentPolicyType and RequestContext is not complete
yet. Because the InternalRequest object needs to know the actual
nsContentPolicyType in order for FetchDriver to be able to use that
information, we can't just store the RequestContext. Therefore, this
patch adds both of these to InternalRequest. Once we get to a stage
where we have a complete mapping of these values, we can store only one
of them and compute the other from it. That requires addressing all of
the TODO comments in the InternalRequest.h documentation.
Use nsCrossSiteListenerProxy.h helpers to implement CORS support.
Several CORS fixes and lots of CORS tests.
Fixes:
Use empty string stream if response has no stream.
Parse Access-Control-Expose-Headers correctly.
Copy over remaining InternalRequest constructor attributes and set unsafe request flag.
Call FailWithNetworkError() in more cases.
Add non-simple Request headers to unsafeHeaders list for CORS check.
Do not AsyncOpen channel directly when CORS preflight is required.
Fix check for simple request method (was checking the opposite condition).
Add various [SameObject]/[NewObject] annotations.
Adds RequestCache enum.
Ensures that cors-with-forced-preflight is translated to cors in getter.
Reject cors-with-forced-preflight as a valid mode value in Request constructor.

This patch has the following big pieces:
HTTP support in FetchDriver, which requires the principal of the caller to be passed.
Managing worker lifetime when a fetch() call is in progress.
Managing worker lifetime when a Response body is being read.
Using nsIPipe to link network streams to Request/Response body streams.
Using nsIInputStreamPump to convert Request/Response body streams into respective types.
Folded:
Bug 1039846 - Fetch API: Use a pipe to immediately start writing HTTP body data to InternalResponse.
Bug 1039846 - Assert bodystream can be set only once
Bug 1039846 - Add feature when handling fetch responses on workers
Bug 1039846 - Try to retarget http fetch delivery off main thread.
Bug 1039846 - Safely consume body using nsIInputStreamPump on workers and main thread.
Bug 1039846 - Retarget body reading to stream transport service.
