Drrip set dueling - with tests (#689)

Extension of PR from @Quangmire with the following improvements:
1. set sampling duel counter type (dscounter) added, which implements
the set sampling duel counter feature utilized by many replacement
policies and prefetchers
2. categorizer type, which implements the sampling utilized by 1 as a
categorizer, evenly splitting a given value into a sampled number of
categories (where 0 and 1 are used as indicators by the dscounter of
those sets to be sampled). How input values are translated to integers
to be sampled relies on a user-defined projection object.
3. static inlines of get_num_samples() and get_sample_rate() which when
provided a population? provides the recommended number of samples and
the corresponding sample rate.
4. The addition of a new msl/stat_methods.h header which includes 1, 2,
and 3 (and in the future could include other structures like this)
5. Tests for features introduced in 1, 2, and 3
