According to a proposed Norwegian standard for alphabetization of which
I've obtained a draft, <u:> is indeed equivalent to u (to my surprise),
and <th> sorts immediately after z.

The correct ordering is algorithmic (based on the EOR) and can not be
accurately represented as a table.

Add collation sequence for no_NO. The same sequence applies to nb_NO
and nn_NO, which are symlinked to no_NO.

The patch in the PR contained a number of errors apparently based on
(sometimes incorrect) pronunciation; for instance, v and w are
distinct letters and should be collated in that order, even if they
are pronounced the same, while <u:> should be collated with u, even
though it is often mispronounced as y. For lack of a solid reference,
I have taken sv_SE and simply changed the last three letters of the
alphabet.
