f88a5dd514 [bugfix/minor] Ensure generativity of solver_types
This ensures that the same solver_types module is not reused
for two different solvers, which would be problematic.
Marked minor because of the low use of multiple instances of a solver.

9a5c23d9c5 [bugfix] termination check after full slice was wrong
When the solver finds a SAT result, it sends the whole
model to the theory, because maybe it can do something
interesting/costly to expand the proof search. After
that there must be a check to see if the theory has effectively done
something, in which case we should resume proof search, or if nothing
has been done, in which case the solver should return that the problem
is satisfiable. That check was incorrect before (checking number of
assumptions, and if the queue is all caught up), because new learnt
clauses (i.e tautologies, which are *not* assumptions) can be added that
do not immediately causes propagation, so that the number of assumptions
and the element queue is constant, but we should still resume the
search.

b6effe691c Added dummy arguments to some functors
Some functors lacked a dummy argument, and thus
could introduce some problems if duplicated (because
they would share the same internal state).

e58cfe1c8f Added function to print unsat core in dimacs format
Thgis is meant to be used for debugging and/or benchmarking purposes.
For instance, when using msat in an application, all unsat cores can
be output this way to different files so that the results can be checked
and easily reproduced in case of errors.

a21807c624 Fix for semantic conflict and decision levels
When faced with a semantic conflict, a new decision
must be made to solve the conflict, however, because
we just backtracked, it is not ensured that the solver
is in a correct state to add a new level, so the decision
is now delayed until propagation has been done.

This specialisation was there to have better performances,
but it doesn't seem to have any impact anymore.
