requests coming from untrusted code (eg. Native Client in Chrome). Use
the same code as XMLHttpRequest to reduce code duplication and have
behavior identical to XHR in Javascript. Add an 'untrustedHTTP' option
to WebURLLoaderOptions, which AssociatedURLLoader can use to determine
if it should check the request method and headers.
