/// This file contains wrappes / helpers to import libcurl into Swift.
/// It is used to implement the NSURLSession API.
///
/// In most cases each `curl_…` API is mapped 1-to-1 to a corresponding
/// `CFURLSession_…` API.
///
/// This approach lets us keep most of the logic inside Swift code as opposed
