    vulkan_ffv1: optimize symbol reader

This was the fastest variant tested.

    avcodec/ffv1: Store slices*planes with the minimum bits needed after remap

This also means that if a plane*slice has only 1 color nothing
is stored after the remap table

This also corrects the RCT offset to the exact value after remap
not a fixed 65536

    avcodec/ffv1: Only allocate fltmap* and bitmap when needed

This reduces memory requirements

    tests/fate/vcodec: Test "default" Huffman tables, too

Since 45eeb1f785d6c726181568db341bbf80b43e32c0
optimal Huffman tables are the default (without slice-threading).
This made the fate-vsynth*-mjpeg-{trell-,}-huffman tests
identical to their corresponding tests without "-huffman".

This is of course wasteful, so switch the two tests with
"-huffman" counterparts back to the default tables.
Also use one of these tests to test slice threaded encoding.
It has so far been untested.
