[JENKINS-24141] Pull ChangeLogSet-related logic out of AbstractBuild

Update WinSW to 2.1.0 and Windows Agent Installer to 1.9

* [FIXED JENKINS-38005] Properly log failure due to empty archive in Pipeline

Since the job result is probably still null at the time that archiving
occurs, we weren't actually logging anything in Pipeline jobs in that
case. That was not ideal. So instead, let's log things, and also let's
update the error message to include a tip to use the allowEmptyArchive
option.

* Reverting to original message

* [JENKINS-42707] AccessDeniedException vulnerability in ReverseBuildTrigger.

* [JENKINS-42707] Added tests to expose the issue

* [JENKINS-42707] Log message according to permission (DISCOVER/READ)

* [JENKINS-42707] Use MockAuthorizationStrategy

* [JENKINS-42707] Remove internationalization for logger

[JENKINS-42959] Correctly compare key algorithms during key verification
[FIXED JENKINS-44046][FIXED JENKINS-43979] Use a larger default key size to fix issues when using SHA256 MACs during Diffe-Helman key exchange against older versions of OpenSSH

Fixes issues encountered following the recent move to the latest Trilead version. These fix 2 underlying issues:

    diffe-helman-sha256 Key Exchange needs at least 2048 bits of data to generate a key against OpenSSH 6.4 and below.
    Known hosts comparison incorrectly compares the hostname against the key value meaning key verification always fails when using known hosts files

Suppressing test flakiness

* [JENKINS-42728] Updating view with CLI using different view type should fail

- Additionally, updating a view using an XML that will be converted by XStream via an alias
  will succeed.

[FIXES JENKINS-42728]

* Remove TestView

* update test

Indicate the actual protocol being served by TcpSlaveAgentListener

[JENKINS-43929] Specific cache control header on ajax.jelly

[JENKINS-44010] NPE in setup wizard

See the changelog: https://github.com/jenkinsci/windows-slave-installer-module/blob/master/CHANGELOG.md

[FIXED JENKINS-44010] It is possible for Jenkins.crumbIssuer to be unset while the setup wizard is running.

Improved OldDataMonitorTest.unlocatableRun

This reverts commit 7fe3a4a3.

* Do not load detached plugins during tests.
Also warn about plugins which force us to create classes.jar.

* Porting POM fix from #2795: we must allow snapshots from repo.jenkins-ci.org so as to be able to test upstream component PRs.

* Fixed failures in tests which assumed detached plugins were being loaded.

* jenkins-test-harness 2.20

* Unreproducible test failure on CI, probably due to timing.
