This ensures that any processing between the MDCT and exponent extraction will
be using clipped coefficients.

period_size is in frames, while the demuxer assumed it was in bytes,
resulting in short reads.

For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes
the stream position without resetting current_id.  The next
matroska_parse_cluster  fails due to calculation of incorrect pos.  So clear
current_id when avio_seek happens in matroska_read_seek.

This is required after the OPT_FUNC2 removal.

Also generalize it, making it accept ints rather than pixel formats.
Allow factorization.
