git send-email --cover-letter apparently didn't let me edit one, so here goes.

This patchset requires my previous one improving the cached bitstream
reader, and serves as its justification. It, basically, moves to using
VLC wherever possible, and in particular when codewords are
sufficiently short/there's some kind of well-behaved laplacian
distribution for codewords that make VLCs efficient.

Total speedup is around 40% here.
