Ownership of the copyright is owned by whoever made the contribution,
and any competent version control system will give you the list of
contributions (and therefore contributors). If a contribution was made
in terms of the GPL, then permission would need to be sought from
everyone who has made a contribution before it could be released under
a different license.
