	src/share/examples/puffs/dtfs: dtfs.c dtfs.h dtfs_vfsops.c

Log Message:
Adapt to changes with mounting file systems.

Introduce a parameter -r to control the root node type.  For example
"dtfs -r 'lnk /etc' /puffs" mounts dtfs with the root node as a
symbolic link to /etc:

jojonaru# ./dtfs -r 'lnk /etc' /puffs
jojonaru# ls -l /puffs
lrw-rw-rw-  1 root  wheel  4 May 17 14:06 /puffs -> /etc
jojonaru# cd /puffs
jojonaru# pwd
/etc
jojonaru#

Extra credit for figuring out how to unmount this file system with
umount(8).

Likewise, "dtfs -r 'chr 2 12' /puffs" makes /puffs (i386) /dev/zero etcetc.
