rename size() to qtail() and introduce shortcuts

Nikolaj Bjorner 73a652cf4b some fixes to backtracking restore points in new solver 2022-11-29 16:42:42 +07:00
Nikolaj Bjorner dd1ca8f6bd 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.

Nikolaj Bjorner ac023935a3 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.
