…ork on unsigned 8-bit values.

Description:

For example, DJB's C code for this hash function is:

uint32 cdb_hash(buf,len)
unsigned char *buf;
unsigned int len;
{
uint32 h;

h = 5381;
while (len) {
--len;
h += (h << 5);
h ^= (uint32) *buf++;
}
return h;
}

This code uses + in place of ^, but that I think is a choice and not just an oversight.
