added "wt_hash" which shows only 60 collisions in 575k values, which
sets it between hashword() and djbx33(). It's also between both in
terms of performance, but the most important part is that its variable
length rotation mechanism should make it really harder to predict and
attack than the other ones.
Aleksandar Lazic has collected many hashing algorithms and put them
in one file to ease benchmarking. Some algos look promising, some
of them have been checked further with uri_hash. Some results on
various systems/hardware are stored in hash_results.txt.
