(cherry picked from commit e9778d20a4)
VLC_MULTI_ELEM contains an uint8_t array that is supposed
to be treated as an array of uint16_t when the used symbols
have a size of two; otherwise it should be treated as just
an array of uint8_t, but it was not always treated that way:
vlc_multi_gen() initialized the first entry of the array
by writing the symbol via AV_WN16; on big endian systems,
the intended value was instead written into the second entry
of the array (where it would likely be overwritten lateron
during initialization).
read_vlc_multi() also treated this case incorrectly: In case
the code is so long that it needs a classical multi-stage lookup,
the symbol has been written to the destination as if via AV_WN16.
On little endian systems, this sets the correct first symbol and
clobbers (zeroes) the next one, but the next one will be overwritten
lateron anyway, so it won't be recognized. But on big-endian systems,
the first symbol will be set to zero and the actually read symbol
will be put into the slot for the next one (where it will be overwritten
lateron).
This commit fixes this; this fixes the magicyuv and utvideo FATE-tests
on big endian arches.

Fixes ffplay playback of unknown layouts, when SDL directly supports the audio
format, such as:
ffplay -f lavfi anullsrc=cl=2C,aformat=s16
Without the patch, "Channel layout change is not supported" errors are
generated because buffersrc (unknown 2 channel) and buffersink (stereo)
negotiated a stereo layout, but the stereo layout was never stored in the
BufferSourceContext.
This fixes a regression of 7251f90972, but this
is more of a regression of the avfilter channel layout conversion
(1f96db959c).
