* Pipe data into HTTP protocol handlers
* Remove unused parameters
* Remove "sending request of http protocol urls" test
Sending request to "http://" in "file://" violates CORS rules and always
fail, before NetworkService somehow Chromium still sent a request even
though the request failed with CORS error, so the test passes while the
test is not valid. With NetworkService no request is sent at all and the
test jsut fails.
So this is an ancient invalid test, as sending http requests have been
fully covered in other tests, I am removing this test.
