Calculate hashtable size to fit into a page instead of a hardcoded 256 buckets hash table. Results in a 1024 buckets hashtable on most systems. Replace old naive extract-8-lsb-bits algorithm with a better algorithm xor'ing 3 or 4 bit fields at the size of the hashtable array index in order to improve distribution if the majority of the lower bits are unused while keeping zero collision behaviour for the most common use case. Thanks to Wang Jian <lark@linux.net.cn> for bringing this issue to attention and to Eran Mann <emann@mrv.com> for the initial idea for this new algorithm.
