* split sat2goal out of goal2sat These two classes need different things out of the sat::solver class, and separating them makes it easier to fiddle with their dependencies independently. I also fiddled with some headers to make it possible to include sat_solver_core.h instead of sat_solver.h. * limit solver_core methods to those needed by goal2sat And switch sat2goal and sat_tactic over to relying on the derived sat::solver class instead. There were no other uses of solver_core. I'm hoping this makes it feasible to reuse goal2sat's CNF conversion from places like the tseitin-cnf tactic, so they can be unified into a single implementation.
