update license terms
As of now, everything except the code imported
from FreeBSD is proprietary.  Of course, it won't
be like this for long, only until we have decided
which license we like to use.  The rationale is
that releasing everything under a copyleft license
later is always easier than doing so immediately
and then changing it afterwards.
Naturally, any changes made before this commit are
still subject to the terms of the CNPL.
