this patchset is about the Matroska muxer. It consists partially of
patches from my earlier patchset [1] that is currently blocked by the
webm_chunk muxer [2].

One focus of this patchset is about improving writing Cues; in
particular, an assert that is triggered if the reserved space for
writing Cues in front exceeds the needed space by one byte is fixed.

Furthermore, the checks involved in writing SeekHeads were fixed. This
goes beyond what was done in the earlier patchset.
