This update reorganizes how Odoo handles incoming requests, moving serving logic to a dedicated module. This change simplifies the system and makes it more efficient, ensuring requests are processed effectively. It’s an internal technical update that improves the underlying infrastructure.

Now that the http module has been split, it makes sense to move the
serving logic to the `router.py` module.

These functions do not need to be exposed from a `Request` instance.
