void InitializeGarbageCollection

(

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

Method which runs the garbage collection. Will start posix_ctx->num_threads in parallel for the task. For posix_ctx->num_threads <= 1 there is a fallback to a sequential version.
