This patchset is sort-of a revival of the part of a patchset I sent
earlier [1], but which couldn't be applied fully because the way the
webm_chunk muxer bypassed the API [2]. Now that this has been fixed [3],
I have taken the opportunity to resend this patchset in an updated form.

It does not yet completely eliminate the limit on the number of tracks
as requested in [4], but no longer counting attachments among the number
of tracks is beneficial even if said limit will be removed.
