v2.31

Full Changelog: v2.30.0...v2.31.0

API changes:

• gf_vect_mul_base() function now returns an integer, matching the return type
  of gf_vect_mul() function (not a breaking change).

Igzip compression improvements:

• Added compress/decompress with dictionary to perf test app.
• Zlib header can be now created on the fly when starting the compression.
• Added isal_zlib_hdr_init() function to initialize the zlib header to 0.

Zero-memory dectection improvements:

• Optimized AVX implementation.
• Added new AVX2 and AVX512 implementations.

Erasure coding improvements:

• Added new AVX512 and AVX2 implementations using GFNI instructions.
• Added new SVE implementation.

CRC improvements:

• Added new CRC64 Rocksoft algorithm.
• CRC x86 implementations optimized using ternary logic instructions and
  folding of bigger data on the last bytes.
• CRC16 T10dif aarch64 implementation improved.
• CRC aarch64 implementations optimized using XOR fusion feature.

Documentation:

• Added function overview documentation page.
• Added security file.

Performance apps:

• Changed performance tests to warm by default.

Example apps:

• Added CRC combine example crc_combine_example for multiple polynomials.

Resolved Issues

• Fixed various compilation issues/warnings for different platforms.
• Fixed documentation on xor/pq gen/check functions, with minimum
  number of vectors.
• Fixed potential out-of-bounds read on Adler32 Neon implementation.
• Fixed potential out-of-bounds read on gf_vect_mul Neon implementation.
• Fixed x86 load/store instructions in erasure coding functions (aligned moves
  that should be unaligned).
• Fixed memory leaks in unit tests.
