Basic Splitting à la Avatar

We don't implement all the stuff from Avatar, in particular all clauses are active whether or not their trail is satisfied in the current model. Trails are only used to make splits easier currently.

Future work may include locking clauses whose trails are unsatisfied.

Depends optionally on the "meta" extension.

module UnionFind : sig ... end

type 'a printer = Format.formatter -> 'a -> unit

Avatar: splitting+sat

val flag_cut_introduced : Libzipperposition.SClause.flag

module type S = sig ... end

module Make
  (E : Libzipperposition.Env.S)
  (Sat : Libzipperposition.Sat_solver.S) : 
  S with module E = E and module Solver = Sat

val k_avatar : (module S) Logtk.Flex_state.key

val k_simplify_trail : bool Logtk.Flex_state.key

val k_avatar_enabled : bool Logtk.Flex_state.key

val get_env : (module Libzipperposition.Env.S) -> (module S)

val extension : Libzipperposition.Extensions.t

Extension that enables Avatar splitting and create a new SAT-solver.
