Dropped the dependency on AthFile from the extract_items() function

The extract_items() function from PoolFile.py is used by the checkSG utility. The dependency on AthFile was replaced by the dependency on the FilePeekerTool. The change required copying of a few auxiliary functions from AthFile/impl.py into PoolFile.py. For the time being this results in code duplication. The duplication will be fixed when we drop AthFile from the Athena main
