    Pinning failure better error (AFNetworking#3425)

    * Error code on pinning failure must be meaningful

    `NSURLErrorServerCertificateUntrusted` instead of `NSURLErrorCancelled`

    * Remove unneeded __block qualifier

    * Add warnings about implementing an authentication challenge block

    * Simpler session-level authentication request handling

    Handle session-level authentication requests exclusively through user-provided `sessionDidReceiveAuthenticationChallenge` block. When `sessionDidReceiveAuthenticationChallenge` is not set, go through the `URLSession:task:didReceiveChallenge:completionHandler:` delegate method instead.

    * Precise error when the server trust is invalid

    Fixes #3165

    * Better server trust error with userInfo dictionary

    * Simplify code flow

    * Better setSessionDidReceiveAuthenticationChallengeBlock: documentation

    * Do not completely bypass the security policy

    Let the possibility to the `taskDidReceiveAuthenticationChallenge` block to fallback to security policy evaluation by returning `NSURLSessionAuthChallengePerformDefaultHandling`.

    * Better expectation descriptions for invalid server trust tests

    * Rename ServerTrustErrorKey into AuthenticationChallengeErrorKey

    * New authentication challenge hander block

    Deprecate `setTaskDidReceiveAuthenticationChallengeBlock:` in favor of the new `setAuthenticationChallengeHandler:` method.

    The new challenge handler allows
    * The user to handle the completion handler themself (fixes #2520)
    * The security policy to be evaluated
    * Aborting the connection with a proper error (see also #3165)

    * Fix nullability annotation

    * Throw if the authentication challenge handler returns an invalid value

    * Document -[AFURLSessionManager setAuthenticationChallengeHandler:]

commit 2da270b
Author: Cédric Luthi <cedric.luthi@gmail.com>
Date:   Sun Jan 5 01:26:41 2020 +0100

    Search for default pinned certificates in the main bundle (AFNetworking#3752)

    Using `[NSBundle bundleForClass:[self class]]` is dangerous because the code will behave differently depending on how AFNetworking is integrated.

    * If it is integrated as a static library (for example using CocoaPods), certificates will be searched in the main bundle.

    * If it is integrated as a framework (for example using Carthage), certificates will be searched in the AFNetworking framework.

    Even though this behavior is documented, this is dangerous. Using the main bundle makes the behavior deterministic.

    Fixes #3575
