…also makes use of an optimized algorithm for x86_64 CPUs without the BMI.
v2: use "defined()" macro
igzip: s/__bsfq/__builtin_ctzll
Per discussion at https://github.com/01org/isa-l/pull/38 __bsfq isn't
defined on clang, but __builtin_ctzll should work same way.
Also, refactor the code a bit.

Remove declarations from huff_codes.h (preserving doc comments where
applicable) and mark functions that are only called within huff_codes.c
as static.

Move current level 2 compression to be level 3 and create a level 2
compression which is the same algorithm as level 1 but with a larger
hashtable.
