Detailed Description

Implementation of FNV-1a with autodetect of sizeof(size_t). This function should work on unsigned char, otherwise it does not correctly implement the FNV-1a algorithm. The existing behaviour is retained for backwards compatibility.

The default value for the seed is optimal for general cases at a certain hash size.
