init of the smartdoge

smartdoge will bring dogeos's packed Fifo to normal SmartOS, which will
be convinient for sys admins having boxes can not access outside world.

smartdoge provides a simple installer script to setup the local smartos env, e.g.,

```
bash # lofiadm -a /path/to/dogeos-iso
/dev/lofi/3
bash # mkdir /opt/dogeiso
bash # mount -F hsfs /dev/lofi/3 /opt/dogeiso
bash # cd /opt/dogeiso
bash # ./smartdoge-install.sh
```

after finishing, you will have `/dogeos` and `/opt/dogeos ready`
