So, for the record, it seems that the additional code in matroskamux was needed
in the past because matroskademux has always been (a bit) buggy in this regard
in that it could send newsegment event (nowadays gap event) (and thereby
kickstarting a muxer's header writing) before actually sending the clut event
(with data needed for this header writing).

Following commit arranges for sending additional "meta-data-events" before
stream synchronization in matroskademux:

    matroskademux: early sending pending codec-data for all streams

    ... at least before syncing across all streams might cause some gap
    activity on any of those streams, notably sparse streams.
