wip: feat(LIA): LIA solver, will rely on LRA solver 
we want to reuse the simplex, but do branch and bound + cutting planes

clause-less steps in proofs 
these steps are checked only once, to accelerate checking, but the
result isn't known.

feat: proper proof production for theory merges in CC 
this involves resolution steps between the lemma (typically a kind of
horn clause with the merge as conclusion) and a bunch of literals
responsible for some equational hypotheses of this horn clause, being true

these occur in datatypes proofs.

feat(proof): do not emit trivial clause_rw steps 
if there is no rewriting going on, we can skip the step.

quip: include all term definitions in proof 
dependency analysis will not catch these, so we include them
unconditionally

also, use names for function application terms, so as to preserve
sharing.

refactor: eager proofs; stronger preprocessing 
proofs are now directly emitted (almost) everywhere, which simplifies
a lot of things. preprocessing is more recursive (a bit too much
really).
