kleines Filmröllchen 111fd1e5fe LibAudio: Optimize FlacLoader by avoiding allocations 
- Pre-allocate and reuse sample decompression buffers. In many FLAC
  files, the amount of samples per frame is either constant or the
  largest frame will be hit within the first couple of frames. Also,
  during audio output, we need to move and combine the samples from the
  decompression buffers into the final output buffers anyways. Avoiding
  the reallocation of these large buffers provides an improvement from
  16x to 18x decode speed on strongly compressed but otherwise usual
  input.
- Leave a FIXME for a similar improvement that can be made in the
  residual decoder.
- Pre-allocate audio chunks if frame size is known.
- Use reasonable inline capacities in several places where we know the
  maximum or usual capacity needed.
