      reworking tags and transformations, stage 1: · 18a0e0b0
      Andrei Paskevich authored
      - introduce a new Theory.tdecl "Meta" to be used for tags
      - simplify cloning procedure, get rid of the th_clone field
      - when a goal proposition is discarded during cloning, 
        it's still keeped in the theory as a "skip proposition",
        this is needed to preserve/clone every local identifier.
        Skip propositions are eliminated during task formation.
      - get rid of a separate Task.tdecl type
      - reorganize the Task.task_hd record:
        * use/clone history is cached in a theory-keyed map;
        * meta-properties are cached in a tagname-keyed map.
        This is done to simplify the fine-grained configuration
        of transformations.

      Not only Theory, but also Task and Transformation 
      do not need to depend on environment. Moreover,
      we don't have to track the clone history in tasks.
      
      The only thing we need to do, is to provide three
      registration functions in Driver, namely:
      
        val register_transform : string -> (unit -> task_t) -> unit
        val register_transform_env : string -> (env -> task_t) -> unit
        val register_transform_clone : string -> (env -> clone -> task_t) -> unit
      
      and then another three for task_list_t.
      
      Then any particular transformation that is going to depend
      on environment or clone_history, must register itself via
      the appropriate registration function. It will be the
      responsibility of Driver to recreate the transformation
      for every new environment and/or clone history. It will
      be easy, given that both [env] and [clone] are physically
      comparable and provide a unique tag.
      
      Thus, the generic interface provided by Transform can be
      completely independent on [env] and [clone].
      
      This commit implements the proposed interface of Task
      and moves the environment stuff into a separate module.
