It is currently possible that such changes leak through from the decoder as
well as a filter could generate such changes itself.
This commit blocks such changed packets unless the encoder declares support.

The QuickTime specification does not contain any hint that the atom
must not be written in some cases and both the QuickTime and the
AVID decoders do not fail if the atom is present.
This change allows to signal (visually) interlaced streams with
a codec different from uncompressed video.
As a side-effect, this fixes ticket #2202

Matroska specification lists support for BlockAdditional element
which is not supported by ffmpeg's matroska parser. This patch
adds grammar definitions for parsing that element (and few other
related elements) and then puts the data in AVPacket.side_data
with new AVPacketSideDataType AV_PKT_DATA_MATROSKA_BLOCKADDITIONAL.

Init code in that if statement goes down from 26716 cycles to 26047
cycles, i.e. the removal of the clear_blocks and smaller memcpy()
together save around 670 cycles.
