applicable) and mark functions that are only called within huff_codes.c
as static.

These globals are only used within huff_codes.c, so they don't need to
be globally visible.

Due to bug in nasm on vinserti32x8 instruction, need nasm v2.13 or
better to build new AVX512 igzip files. Changed the configure test
and doc to reflect.

Currently can't test because yasm doesn't support avx512 but should
get the syntax correct for when it does.

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.

Moved the afl fuzz test and added llvm fuzz tests including inflate
and round trip compress and inflate. Currently only works with clang,
std makefile and libFuzzer installed. Need to add checking and
support later when libfuzzer is more tightly integrated into the
compiler.
