Revision 36876

  In TPacketizerFile:
  - Extend flexibility of the input map content by adding support for lists of TFileInfo, maps of
    TFileCollections and urls as key valus; this allows to run directly on the output of
    TFileCollection::GetFilesPerServer.
  - Add option to not process the files not assigned to any worker; this allows to write selectors
    to perform a given action only on files local to workers.
