Ehsan Akhgari cd8bb1e29a Bug 1147699 - Part 1: Move Request::mContext to InternalRequest, and determine the mapping to nsContentPolicyType; r=nsm
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.
