*  Fix: Undo a performance regression introduced in OkHttp 4.0 caused by differences in behavior
    between Kotlin's `assert()` and Java's `assert()`. (Kotlin always evaluates the argument; Java
    only does when assertions are enabled.)

 *  Fix: Honor `RequestBody.isOneShot()` in `HttpLoggingInterceptor`.
