- especially with the TLDs

* JENKINS-50412 - Fingerprints logs should be less verbose

Eliminate the logging line that says
possibly trimming /var/jenkins_home/fingerprints/[...]
This line fills up the fingerprints log file with repetitive, useless information.
The operation it calls provides its own logging that can be turned on if detailed
logging is actually needed instead of running this one repeatedly.

Also, while in the area, convert a couple of FileFilter inner classes to lambdas
and inline them. This reduces unnecessary boilerplate and improves clarity.

In order to make this change testable, I elected to remove the final restriction on the
class and annotate the class as restricted. This allows me to create unit tests for
this change and also verify existing capability at the appropriate level.

* Watch out for varying line endings.

Use a reliable check.

* Correct a few minor issues caught in review.

* Change to correct access modifier.

* Better separation between content and display
- also put the version for the RootUrlNotSetMonitor and the HttpResponses new method

* Add blank line

Cleanup since Javadoc tags

The special old module for doxia seems not needed.
I suspect that it is because since 2012 when it was released, the Markdown
support got done in standard.

IIUC this was pulling in some very old doxia versions, which was
incompatible with maven-fluido-skin which I needed to bump from current
1.3.0 to 1.7 for https://github.com/jenkins-infra/core-taglibs-report-generator
to work again.
