Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * NOTE! This filesystem is probably most useful
- * not as a real filesystem, but as an example of
- * how virtual filesystems can be written.
- *
- * It doesn't get much simpler than this. Consider
- * that this file implements the full semantics of
- * a POSIX-compliant read-write filesystem.
- *
- * Note in particular how the filesystem does not
- * need to implement any data structures of its own
- * to keep track of the virtual data: using the VFS
- * caches is sufficient.
