    google: Added "GVFS_GOOGLE_DEBUG" env var to log all the entries in cache
    
    To better check the state of cache before and after a copy operation is
    performed, we have added a function which checks for "DEBUG_CACHE"
    environment variable (any value) and logs all the entries to console.
