The spec says
9: Interlaced with bottom field displayed first and top field stored first
14: Interlaced with top field displayed first and bottom field stored first
And avcodec.h states
AV_FIELD_TB, //< Top coded first, bottom displayed first
AV_FIELD_BT, //< Bottom coded first, top displayed first

Should also go into libav 12. This feature is only a couple months old
so it's not affecting any other stable release.
A check for files created with old lavf versions in the matroska demuxer
to detect wrongly muxed files and workaround them would also be a good
idea.
Minor version is bumped for this purpose.
