Support the -D command line option for running benchmarks. The benchmark code was slightly restructured to factor out the calls that need to be different for each benchmark scenario. Since there are now 4 scenarios (all combinations of fast/HC and with/without dictionary), the logic was getting somewhat convoluted otherwise. This was done by extending the compressionParameters struct that previously contained just a single function pointer. It now contains 4 function pointers for init/reset/compress/cleanup, with the related state. The functions get a pointer to the structure as their first argument (inspired by C++), so that they can access the state values in the struct.
