void InitializeGarbageCollection ( struct fs_traversal_context ctx)

This file is part of the CernVM File System. Initializes garbage collection by setting up the corresponding hash map in the fs_traversal_posix_context The initialization uses the data stored in the file at [data directory] + POSIX_GARBAGE_DIR + POSIX_GARBAGE_FLAGGED_FILE

This file contains a fixed length concatenation of inodes (type ino_t) which should be checked and deleted upon garbage collection
