[dmd-internals] DMD copyright assignment

[Daniel Murphy via dmd-internals]

You don't need to deal with it in the future, because boost allows you
to change to a more restrictive license if necessary.  eg We could
change it to BSD or GPL _without_ needing copyright assignment.  This
is only a problem if we want to remove restrictions, and there doesn't
seem to be any point to doing that.

Also, AIUI we will not be able to change the license of phobos and
druntime anyway, since there is no copyright assignment for those.
We're 'stuck' with boost either way.
