avcodec/vorbisenc: Combine codebooks, avoid relocations
The Vorbis encoder has an array of a structure containing all the ingredients for a codebook; this includes a pointer to the actual codebook and some even have a pointer to an array containing quant values. Each of these real codebooks is an array of its own. These pointers lead to relocations and therefore the array will be placed in .data.rel.ro and not in .rodata. This commit avoids the pointers altogether by combining all the actual codebooks into one big array; the actual codebooks are now accessed consecutively by incrementing the pointer used to access them by the length of the actual codebook that has just been dealt with (said length is contained in the structure describing the codebook). There is no downside to this given that these codebooks are already only used once during init. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
