Add NetworkService support for CefURLRequest (see issue #2622).

Browse Source 
Requests created using CefURLRequest::Create are not associated with a
browser/frame. When originating from the render process these requests cannot be
intercepted and consequently only http(s) and blob requests are supported. To
work around this limitation a new CefFrame::CreateURLRequest method has been
added that allows the request to be associated with that browser/frame for
interception purposes.

This change also fixes an issue with the NetworkService implementation where
redirected requests could result in two parallel requests being sent to the
target server.

To test: URLRequestTest.* tests pass with NetworkService enabled.

// Create a new URL request. Only GET, POST, HEAD, DELETE and PUT request
// methods are supported. Multiple post data elements are not supported and
// elements of type PDE_TYPE_FILE are only supported for requests originating
// from the browser process. Requests originating from the render process will
// receive the same handling as requests originating from Web content -- if
// the response contains Content-Disposition or Mime-Type header values that
// would not normally be rendered then the response may receive special
// handling inside the browser (for example, via the file download code path
// instead of the URL request code path). The |request| object will be marked
// as read-only after calling this method. In the browser process if
// |request_context| is empty the global request context will be used. In the
// render process |request_context| must be empty and the context associated
// with the current renderer process' browser will be used.
// Create a new URL request that is not associated with a specific browser or
// frame. Use CefFrame::CreateURLRequest instead if you want the request to
// have this association, in which case it may be handled differently (see
// documentation on that method). Requests may originate from the both browser
// process and the render process.
//
// For requests originating from the browser process:
// - It may be intercepted by the client via CefResourceRequestHandler or
// CefSchemeHandlerFactory.
// - POST data may only contain only a single element of type PDE_TYPE_FILE
// or PDE_TYPE_BYTES.
// - If |request_context| is empty the global request context will be used.
// For requests originating from the render process:
// - It cannot be intercepted by the client so only http(s) and blob schemes
// are supported.
// - POST data may only contain a single element of type PDE_TYPE_BYTES.
// - The |request_context| parameter must be NULL.
//
// The |request| object will be marked as read-only after calling this method.
