Windows still has a relatively short max path length limitation
in some situation which the core tends to violate.
The patch introduces a test script activated in bamboo to test
the relative path length does not exceed an arbitrary number and
shortens some long path segments.
This allows a statement "If your source / unpack location path
prefix is not longer than x characters, you are fine".

Currenty 'fileinfo' is listed as required php extension in
SystemEnvironment/Check but it is currently not really required
and prevents from installing TYPO3 on Systems where it is not
present (e.g. Mircosoft Azure Cloud)

The class is currently only used once in the core in
"TYPO3\CMS\Core\Type\File\FileInfo" and only when it exists,
so it is not really a hard dependency.

Also grepping on an installation folder does not find any match
where \finfo is really required.
