e45ed15594 avcodec/libaomdec: auto insert dump_extra bitstream filter 
Some containers, like Matroska, may propagate key frames with no Sequence
Header OBU since it's provided in extradata instead.
With this change, the Sequence Header will be appended to the packet data
before calling aom_codec_decode().

ec517ad9f9 fate: add tests for audio channel up-/downmixing with pan filter 
Add tests for upmixing and downmixing with audio channel counts that
have a corresponding default layout and also tests where there is no
default layout.

Update the existing "stereo4" test so it actually outputs stereo like
the other stereo tests. Rename the previous "stereo4" test into
"upmix1".

8b710ea5e7 swresample: Use channel count in rematrix initialization 
Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails.

This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout.
