avcodec/rv34: Simplify getting right VLC For both RealVideo 3.0 as well as RealVideo 4.0 the VLC table to use depends upon the slice's quantization parameter; these are coded on five bits in the bitstream and are therefore in the range of 0..31; yet the last element here is not valid and therefore the quantizer is clipped to the range 0..30 to get the index. But this is unnecessary: One can just add one element more to the relevant array to avoid the clipping.

For the latter case, one just needs to store the length of each symbol and create the codes according to the other rules; no explicit code or symbol array must be stored. The former case is also treated in much the same way by artificially assigning a length of zero to the symbol (...)

Each tree can contain at most 32 leafs; typically they contain exactly 32 with the 32 symbols forming a permutation of 0..31. Yet the standard does not impose either of these requirements. It explicitly allows less than 32 leafs and multiple codes with the same token. But our decoder used an algorithm that required the codes->token (...)
