ChangeLog, debug_cmds.ct, debugfs.8.in, debugfs.c, dump.c, ls.c:

  debugfs.8.in: Documented new behaviour.
  ls.c (ls_l_file): Fix Y2K bug -- was printing 22-May-100 for recent
  	files.  Switched to 4-digit years.
  dump.c, debug_cmds.ct (do_rdump): Add new debugfs command "rdump",
  	which recursively dumps a directory and its contents.
  	(fix_perms): New function.  Break permission-fixing code out of
  	dump_file() so it can be called by rdump code as well.
  	(dump_file): Call fix_perms().
  debugfs.c, debug_cmds.ct (do_lcd): Add new debugfs command "lcd",
  	which changes the cwd on the native filesystem.
  debugfs.c (open_filesystem): Extra args for superblock, blocksize, and
  	catastrophic mode.  Changed callers.
  	(do_open_filesys, main): Accept new -b, -s, -c options for
  	open_filesystem.
ChangeLog, mkdir.c:
  mkdir.c (ext2fs_mkdir): Read the parent directory's inode earlier, so
  	that if there's an error reading it, we can more cleanly back out of
  	the operation.
version.h:
  Update version file for WIP release.
