FLAC in MKV doesn't play or crashes

Description

files in http://astrange.ithinksw.net/qt/

ef.mkv is remuxed from the original .flac.

ef-flacimport.mov is imported from the original via FLAC_Import and works.

ef-perian.mov is imported from the mkv and crashes XiphQT.

flac-nosound.mov plays a loud pop then no sound.

I don't think we should depend on XiphQT to be installed for this to play, but I don't know about adding a new audio codec right before release, especially one with 5.1 support.

The problem here is:

* the FLAC atom generation in the mkv demuxer was completely wrong, so I turned it off. * XiphQT doesn't try to recover from a missing atom, so it just assumes a bitrate and sample rate. This doesn't work if they're different from what's assumed.

The proper fix would be to generate the atom properly; I found the appropriate part of ffmpeg but forgot where it was...
