matroskaenc: Bump DocTypeVersion to 4

The muxer has been creating files with v4 elements for some time now,
and especially now that we can mux non-experimental Opus files, reporting
the DocTypeVersion as 2 is not correct.

pcm-dvd: Minor leftovers

pcm-dvd: Support channel configuration changes

The sample buffering logic does not take into account that the blocksize
could change. Reset the buffer if the channel configuration changes,
since if there are leftover samples, it is most likely a broken or
misconcatenated stream. This could lead to negative numbers for
missing_samples during decoding.

Thanks to Michael Niedermeyer for pointing these out.
