    dictionaries (map of BDD variables to LTL formulae).  This was
    cumbersome, because to multiply two automata we had to build a
    common dictionary (the union of the two LTL formula spaces), and
    install wrappers to translate each automaton's BDD answers into
    the common dictionary.  This translation, that had to be repeated
    when several products were nested, was time consuming and was a
    hindrance for some optimizations.
    In the new scheme, all automata involved in a product must
    share the same dictionary.  An empty dictionary should be
    constructed by the user and passed to the automaton' constructors
    as necessary.
    This huge change removes most code than it adds.
    * src/Makefile.am (libspot_la_LIBADD): Add misc/libmisc.la.
    * src/misc/bddalloc.hh, src/misc/bddalloc.cc: New files.  These
    partly replace src/tgba/bddfactory.hh and src/tgba/bddfactory.cc.
    * src/misc/Makefile.am: Adjust to build bddalloc.hh and bddalloc.cc.
    * src/tgba/bddfactory.hh, src/tgba/bddfactory.cc,
    src/tgba/dictunion.hh, src/tgba/dictunion.cc,
    src/tgba/tgbabdddict.hh, src/tgba/tgbabdddict.cc,
    src/tgba/tgbatranslateproxy.hh, src/tgba/tgbatranslateproxy.cc:
    * src/tgba/bdddict.hh, src/tgba/bdddict.cc: New files.  These
    replaces tgbabdddict.hh and tgbabdddict.cc, and also part of
    bddfactory.hh and bddfactory.cc.
    * src/tgba/bddprint.cc, src/tgba/bddprint.hh: Adjust to
    use bdd_dict* instead of tgba_bdd_dict&.
    * src/tgba/succiterconcrete.cc (succ_iter_concrete::next()):
    Get next_to_now from the dictionary.
    * src/tgba/tgba.hh (tgba::get_dict): Return a bdd_dict*,
    not a const tgba_bdd_dict*.
    * src/tgba/tgbabddconcrete.cc, src/tgba/tgbabddconcrete.hh:
    Adjust to use the new dictionary, stored in data_.
    * src/tgba/tgbabddconcretefactory.cc,
    src/tgba/tgbabddconcretefactory.hh: Likewise.  Plus
    now_to_next_ is now also stored in the dictionary.
    * src/tgba/tgbabddconcreteproduct.cc: Likewise.  Now
    that both operand share the same product, there is not
    point in using tgba_bdd_translate_factory.
    * src/tgba/tgbabddcoredata.cc, src/tgba/tgbabddcoredata.hh:
    Store a bdd_dict (taken as constructor argument).
    (tgba_bdd_core_data::~tgba_bdd_core_data): Remove.
    (tgba_bdd_core_data::translate): Remove.
    (tgba_bdd_core_data::next_to_now): Remove (now in dict).
    (tgba_bdd_core_data::dict): New pointer.
    * src/tgba/tgbabddfactory.hh: (tgba_bdd_factory::get_dict): Remove.
    * src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh:
    Adjust to use the new dictionary.
    * src/tgba/tgbaproduct.cc, src/tgba/tgbaproduct.hh: Likewise.  Do
    not use tgba_bdd_dict_union and tgba_bdd_translate_proxy anymore.
    * src/tgbaalgos/lbtt.cc, src/tgbaalgos/save.cc: Adjust to
    use bdd_dict* instead of tgba_bdd_dict&.
    * src/tgbaalgos/ltl2tgba.cc, src/tgbaalgos/ltl2tgba.cc: Likewise.
    (ltl_to_tgba): Take a dict argument.
    * src/tgbaparse/public.hh (tgba_parse): Take a dict argument.
    * src/tgbaparse/tgbaparse.yy (tgba_parse): Take a dict argument.
    * src/tgbatest/explicit.cc, src/tgbatest/explprod.cc,
    src/tgbatest/ltlprod.cc, src/tgbatest/mixprod.cc,
    src/tgbatest/readsave.cc, src/tgbatest/spotlbtt.cc,
    src/tgbatest/tgbaread.cc, src/tgbatest/tripprod.cc: Instantiate
    a dictionary, and pass it to the automata' constructors.
    * src/tgbatest/ltl2tgba.cc: Likewise, and remove the -o (defrag)
    * iface/gspn/gspn.hh (tgba_gspn::tgba_gspn): Take a bdd_dict argument.
    (tgba_gspn::get_dict): Adjust return type.
    * iface/gspn/gspn.cc: Do not use bdd_factory, adjust to
    use the new dictionary instead.
