David Howells 32759f7d7a cachefiles: Implement a function to get/create a directory in the cache ... Implement a function to get/create structural directories in the cache.

The directory in memory are marked with the S_KERNEL_FILE inode flag whilst they're in use to tell rmdir to reject attempts to remove them. Changes ======= ver #3: - Return an indication as to whether the directory was freshly created.
