To further isolate problems during remote trouble-shooting of remoting, define a switch to bypass NIO and use classic blocking I/O transport. Ample warning to prevent accidental dependencies from other Java code.

Should be @Restricted or final
This is too draconian to my taste and @deprecated is sufficient as a warning, but whatever.

The change introduces one serious bugfix (JENKINS-39596) and a bunch of various diagnostics improvements. Bugfixes: * [JENKINS-39596](https://issues.jenkins-ci.org/browse/JENKINS-39596) - Jenkins URL in `hudson.remoting.Engine` was always `null` since `3.0`. It was causing connection failures of Jenkins JNLP agents when using Java Web Start. ([PR jenkinsci#131](jenkinsci/remoting#131)) * [JENKINS-39617](https://issues.jenkins-ci.org/browse/JENKINS-39617) - `hudson.remoting.Engine` was failing to establish connection if one of the URLs parameter in parameters was malformed. ([PR jenkinsci#131](jenkinsci/remoting#131)) Improvements: * [JENKINS-39150](https://issues.jenkins-ci.org/browse/JENKINS-39150) - Add logic for dumping diagnostics across all the channels. ([PR jenkinsci#122](jenkinsci/remoting#122), [PR jenkinsci#125](jenkinsci/remoting#125)) * [JENKINS-39543](https://issues.jenkins-ci.org/browse/JENKINS-39543) - Improve the caller/callee correlation diagnostics in thread dumps. ([PR jenkinsci#119](jenkinsci/remoting#119)) * [JENKINS-39290](https://issues.jenkins-ci.org/browse/JENKINS-39290) - Add the `org.jenkinsci.remoting.nio.NioChannelHub.disabled` flag for disabling NIO (mostly for debugging purposes). ([PR jenkinsci#123](jenkinsci/remoting#123)) * [JENKINS-38692](https://issues.jenkins-ci.org/browse/JENKINS-38692) - Add extra logging to help diagnosing `IOHub` Thread spikes. ([PR #116](jenkinsci/remoting#116)) * [JENKINS-39289](https://issues.jenkins-ci.org/browse/JENKINS-39289) - When a proxy fails, report what caused the channel to go down. ([PR jenkinsci#128](jenkinsci/remoting#128))
