There are known issues (deadlocks) with CFNetworkHandler: #25634

CFNetworkHandler is obsolete, so we won't fix any such issues, so to avoid deadlocks, just avoid testing CFNetworkHandler.

Fixes #25634.

Pull request overview

This PR updates the monotouch-test HTTP-related test suites to stop running test cases that use System.Net.Http.CFNetworkHandler, due to known deadlocks in that handler (tracked in #25634). This keeps CI from hanging while preserving coverage for the supported handlers.

Changes:

  • Mark CFNetworkHandler TestCase instances as ignored in MessageHandlers.cs for DNS failure and redirect/auth header scenarios.
  • Mark the CFNetworkHandler TestCase as ignored in HttpClientTest.cs for the post-send modifiability test.
