rcorder(8)-ed startup script

Browse Source 
With

```sh
bastille_enable="YES"
bastille_rcorder="YES"
```

in `/etc/rc.conf`, the script will the script will start all jails, except jails
with "KEYWORD: nostart" in jail.conf.

Example of `jail.conf` with `KEYWORD: nostart`:

```
jailname {
...
}
```

`PROVIDE:` is optional. Actually all `rcorder(8)` labels are optional, but we
can use it to build jail dependencies. For instance, if we have jail `db` and
jails `alfa` and `zeta`, we can configure it so both jails require jail `db`:

`alfa/jail.conf`:
```
alfa {
...
}
```

`zeta/jail.conf`:
```
zeta {
...
}
```

`db/jail.conf`:
```
db {
...
}
```

With this configuration jail `db` will start first and stop last.
