+ - switch to a multiplicative hash (developed with Steinar Gunderson),
+ which is faster on modern cpus and compresses a bit better. The old
+ hash function which uses only shifts is still available.
+ - allow user configurable hash table slots, which makes it possible
+ to use e.g. 16 bit offsets for a smaller hashtable (if your data is
+ always < 64kb).
