Replaced remaining literal constants to symbolic ones in the DWord smoking algorithm
DWord smoker modified to support even STEP==FILTER==1 values
Also compute maximum block entropy
Multiple files processing support
Dynamic memory allocation in the DWordSmoker
WordSmoker: computes entropy of 16-bit words (1 GB/s)
Order1Smoker: computes order-1 entropy of 8-bit bytes (0.7-1.5 GB/s)
