The directional intra predictors either don't care about order (dc, h,
dc_left, tm), or they prefer inverted order (vr, dr, hd). This allows
more efficient SIMD implementations.

Use same function for segmentation map writing also.

The spec doesn't describe how it should be decoded so this is probably
the safest thing to do. Fixes valgrind errors on fuzzed11.ivf and fixes
valgrind errors on fuzzed10.ivf differently.

Fixes valgrind warnings on fuzzed10.ivf.

When request_channel_layout is 0,
all substreams should be decoded.

Thanks to Michael Niedermayer for spotting.

Also fix a mismatch between the parser and
decoder when request_channel_layout is a
subset of Stereo.

When request_channel_layout is 0,
all substreams should be decoded.

When mixing 3 front channels into 2, the center channel is mixed into left and right with the center mix level, not -3dB.

Don't decode further substreams if request_channel_layout
is a subset of the current substream's channel_layout.

Before, we would only discard further substreams if
request_channel_layout matched the substream's
channel_layout extactly, thus decoding additional
channels which the caller would probably end up downmixing.
