NavigationThrottleRunner2: Introduce NavigationThrottleRegistryImpl

This patch factors out common logic in the NavigationThrottleRunner to
the newly introduced NavigationThrottleRegistryImpl so that the logic
can be shared with the new NavigationThrottleRunner2 in the near future.

This new class also helps to decouple the NavigationRequest and
NavigationThrottleRunner so that we can remove risky downcast and remove
the unnecessary Delegate interface. Now we can write
NavigationThrottleRunner tests easily and safely without such ad-hoc
patches.

NO_IFTTT=replace the enum declaration

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.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

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.

If you found a bug, please file it at https://crbug.com/new.
