bpo-38216: Allow bypassing input validation
bpo-36274: Also allow the URL encoding to be overridden.
bpo-38216, bpo-36274: Add tests demonstrating a hook for overriding validation, test demonstrating override encoding, and a test to capture expectation of the interface for the URL.
Call with skip_host to avoid tripping on the host checking in the URL.
Remove obsolete comment.
Make _prepare_path_encoding its own attr.
This makes overriding just that simpler.
Also, don't use the := operator to make backporting easier.
Add a news entry.
_prepare_path_encoding -> _encode_prepared_path()
Once again separate the path validation and request encoding, drastically simplifying the behavior. Drop the guarantee that all processing happens in _prepare_path.
