Switching to randomly generated hostnames

[James Cameron]

Using the wireless device MAC address as the basis of the hostname seems
wrong to me.  It is an overload of meaning.  It also has an impact if
the wireless device is changed.

I'm also amused that the hostname needs to be unique, but that is
probably a different issue.

If the need for it to be unique can't be avoided, then at least set it
based on serial number.  That at least is available very soon after
boot, in /proc/device-tree/ or /ofw/, and we have utilities for
accessing it.

Like the wireless device MAC address, the serial number may also change,
so the code must be able to cope with this too.
