Add a new NavigationThrottle for HTTP-error navigations with empty body

Previously, error page navigations initiated by the renderer will commit
synchronously and only notify the browser at DidCommit time, making it
have to create a NavigationRequest for the navigation at DidCommit time.
One of the cases that do that is main-frame navigations with error HTTP
status code and an empty response body.

This CL makes it so that we detect that case in the browser side instead
of the renderer side by adding a NavigationThrottle that will defer main
frame navigations with an error HTTP status code until we can determine
if its response body is empty or not, and commit an error page instead
of the original (empty) page if so.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
