* repositories (see {@link repository::has_moodle_files()}), references to
* internal files are updated immediately when source is modified.
*
* Referenced files may optionally keep their content in Moodle filepool (for

*
* Note that this function may be run for EACH file that needs to be synchronised at the
* moment. If anything is being downloaded or requested from external sources there
* should be a small timeout. The synchronisation is performed to update the size of
* the file and/or to update image and re-generated image preview. There is nothing
* fatal if syncronisation fails but it is fatal if syncronisation takes too long
* and hangs the script generating a page.
