Fix for Remove random_compat, no longer needed #3262

use SVG icons for media file links

The dokuwiki template should probably be adjusted a bit. Old png files
are not yet removed as they may be used elsewhere still.

readded $jump mechanism, removed unused functions

fix use of $rev parameter

fix entity definition

reenable the option to display a relative namespace for media files

This is used when searching for media files

simplified the media_searchlist tests

make use of the new media file classes

This just crudely replaces the calls to the old functions with usage of
the new classes. This however already works and makes (manual) testing
of these classes

This just crudely replaces the calls to the old functions with usage of
the new classes. This however already works and makes (manual) testing
of these classes easier.

Next steps: remove the old media_printfile and media_printfile_thumbs
methods and fix/drop/replace the tests depending on them. search_media
might be obsolete, too already.

For search results the display classes need to show full namespaces.
This needs to be fixed again. No idea about the jump mechanism, yet.

first go a refactoring the media manager

For now this only adds code. This takes care of encapsulating media file
information and has some UI classes to display those files in the
fullscreen media manager and the popup.

The code is untested and not integrated to run, yet. Next step is to
replace the parts in the media manager to call this new code (and fix
any bugs).

I tried not to change much HTML yet. This can be done later. For now the
goal is to just make it run again.

The attempt in 7bbf38eeb4aaf5ac1c3b4a2cea4cc0b371890f4a to not run
checks twice for our own internal pull requests seem not to have worked,
because checks in external PRs were no longer executed.

This is another approach to achieve the same based on code found at
https://github.com/Dart-Code/Dart-Code/blob/764f121f9abe5f4496528d35277946d4130af93d/.github/workflows/build-and-test.yml#L10-L12

do not repeat successful security checks. fixes #3363

This avoids creating lots of 403 errors for properly secured data
directories. Only one successful check per browser session will be
executed.

lazy load images

This adds the loading="lazy" attribute to embedded images and the
thumbnails in the media manager. This instructs modern broswers to load
images on demand when they come into view.
