add flag to control non-linear substitutions: smt.solve_eqs.linear is by default false, setting it to true restricts solutions to substitutions to only use linear terms. This can have an effect on cross-multiplication of nested substitutions

- 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.

also, bug fixes to elim_unconstrained (elim_uncnstr2) which is to replace legacy tactic for eliminating unconstrained constants.

wip - adding context equation solver
...
the solve_eqs_tactic is to be replaced by a re-implementation that uses solve_eqs in the simplifiers directory.
The re-implementation should address efficiency issues with the previous code.
At this point it punts on low level proofs. The plan is to use coarser
dependency tracking instead of low level proofs for pre-processing. Dependencies can be converted into a proof hint representation that can be checked using a stronger checker.
