When tone portamento is used on an instrument with an NNA and the old note and the new note have different samples, the tone portamento should cancel the NNA and duplicate check for that note but should not actually be played. libxmp was canceling the NNA correctly before, but it was clearing the entire mixer voice instead of just the current NNA state. libxmp was NOT canceling the duplicate check before in this situation, which allowed the portamento note to incorrectly cancel past notes. test/test.c change is due to an extra anticlick decay being generated due to not clearing its state anymore.
