If a user passes an invalid size for window bits it could have triggered an
undefined shift by larger than variable size.

This patch introduces the base, avx and sse optimized zero detect memory function.
The zero detect memory function tests if a memory region is all zeroes. If all the
bytes in the memory region are zero, the function return a zero. Otherwise, if the
memory region has non zero bytes, the zero detect function returns a 1.

have been removed.

These can be replaced with the <stdint.h> types.
Additionally, the existing definitions weren't correct on some platforms
(e.g. IA-32, where 'long', used for INT64/UINT64, is only 32 bits).

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.

Merge crc32_gzip_refl function definitions, base code, multi-binary
code into crc32.h, crc32_base,c and crc_multibinary.asm in order to
keep consistency. Add crc32_gzip_refl files into crc/Makefile.am
Original crc32_gzip_refl removed NOT operation, re-add it.

Add a program calculating some of the exact conditions where gf_gen_rs_matrix
works, add comments stating these bounds to gf_gen_rs_matrix, and fix erasure
code test that violates the bounds.

1. Add normal and reflected bits order functions for ISO format and
Jones coefficients format.
2. Add a multi-binary macro for crc64 functions.
3. In order to decrease number of repeated test.c and perf.c files,
using crc64_funcs_test.c and cr crc64_funcs_perf.c.
4. Add crc64_example.c to take the demonstration role.

crc64_ecma_norm is used for the normal format.
crc64_ecma_refl is used for the refleced format.

Create a flag signifying the existence of buffer history so a literal does not
have to be encoded on every call of isal_deflate_body and isal_deflate_finish.
