[PATCH v3 2/4] hash: add dynamic polynomial calculation

Current polynomial table has the following limitations: 1. It has polynomials up to degree 16 2. For each degree there are only 4 polynomials The above results in less entropy when generating Toeplitz hash key subsequences. This patch replaces the current static table approach with dynamic polyn
