 *  Fix: Never throw converting an `HttpUrl` to a `java.net.URI`. This changes
    the `uri()` method to handle malformed percent-escapes and characters
    forbidden by `URI`.
 *  Fix: When a connect times out, attempt an alternate route. Previously route
    selection was less efficient when differentiating failures.
 *  New: `Response.peekBody()` lets you access the response body without
