cachefiles: Implement a function to get/create a directory in the cache
Implement a function to get/create structural directories in the cache.
This is used for setting up a cache and creating volume substructures. 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.
