Duplicate files

There are files that exists on multiple file servers. A harmless case is where a file was copied from one to another server duplicating it. There are also
files for which a file exists on two (or more) servers but their contents is different.

From the file listing the file names that exists on more than one server are extracted. For each of these file names we check if the size of the different instances are equal or differ.

The file summary_duplicates shows for the different FGST sub-directories how many of these files exists.
The duplicates sub-directory in the file-listing output shows the detail for all these files (dup_<path> files). It also contains the files named notequal_dup_<path> that only shows those file names for which the file sizes differ.
