Refactored CnfStream to work with the bv theory Bitblaster:
* separated SatSolverInput interface class into two classes:
- TheoryProxy for the sat solver to communicate with the theories
- SatSolverInterface abstract class to communicate with the sat solver
* instead of using #ifdef typedef for SatClauses and SatLiterals, now there are CVC4 SatLiteral/SatClause types and mappings between them and the internal sat solver clause/literal representation
* added abstract classes for DPLLSatSolver and BVSatSolver different interfaces
Replaced TheoryBV with bitblasting implementation:
* all operators bitblasted
* only operator elimination rewrite rules so far
