CHL - C hashing library. Collection of hash functions

Non-Cryptographic functions:

• djb2
• pjw-(32/64)
• fnv1[a]-(32/64)
• crc32(b/c)
• jenkins
• md5
• sha1

Cryptographic functions:

• siphash-2-4
• sha2-(224/256/384/512)
• sha2-512/(224/256)
• ripemd-(160/320)
• hmac-*

chl_xxx_ret_t - hash function type result
chl_xxx_key_t - key type for hash function (maybe not exist)
chl_xxx_calc_span - find hash value of memory span (ptr + length)
chl_xxx_calc_file - find hash value of file (use rb mode)
where xxx - name of hash function.

CHL_DEFAULT - name of hash function by default, if not defined then equal djb2
use for macros: chl_ret_t, chl_key_t, chl_calc_span, chl_calc_file.
