  pcm-dvd: Support channel configuration changes
Merged-by: Michael Niedermayer <michaelni@gmx.at>

Drop a pointless branch in uninit and use the compact copyright.

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.

Its the width in bytes and not the linesize or stride.
This makes the naming more consistent with the rest of the codebase

This reverts commit 51dab60c.

this fixed nothing, and was just the result of assuming that the
variable named linesize was the linesize. Its not, its the width
in bytes which was already correct.

  Set bits_per_raw_sample when reading j2k frames.
  libopenjpegdec.c: Correctly scale gray16 output if precision < 16
  Use rc_max_rate if no video bit_rate was specified when muxing mxf_d10.
  Store the video bit_rate in the context when muxing mxf.
