move qhead to attribute on the state instead of the simplifier,
...
- add sat.smt option to enable the new incremental core (it is not ready for mainstream consumption as cloning and other features are not implemented and it hasn't been tested in any detail yet).
- move "name" into attribute on simplifier so it can be reused for diagnostics by the seq-simplifier.

introduce sat-smt-solver
...
in an iteration of inc-sat-solver introduce sat-smt-solver to allow incremental pre-processing.
The aim is to allow incrementally handling formulas while at the same time retaining the main benefits of global in/pre-processing that change models. Previous incremental solving capabilities have been limited to use pre-processing that does not require model conversion.

port bit-blaster to simplifiers
...
inc_sat_solver uses bit-blaster, card2bv and max_bv_sharing.
By turning these into simplifiers it will be possible to remove
dependencies on tactics and goals in inc_sat_simplifier and instead use a modular and general incremental pre-processing infrastructure.
