* src/tgbaalgos/simulation.cc: Buid a tgba_digraph as the result of the
simulation.
* src/tgba/tgbagraph.hh (create_namer): New function.
* src/tgbatest/basimul.test: Add an additional test case that caused a
bug fixed in a previous patch.
* src/tgbatest/sim.test: Adjust.

* src/graph/ngraph.hh (alias_state): New method.
* src/graphtest/ngraph.cc: Use it.

* src/graph/graph.hh: Add some framework to erase transitions, and
defrag the resulting transitions_ vector on demand.  Also remove
the nb_states() and nb_transitions() because num_states() and
num_transitions() already exist.
* src/graphtest/graph.cc, src/graphtest/ngraph.cc: Adjust to
use num_states().
* src/tgba/tgbagraph.hh (merge_transitions): New method.
* src/misc/hash.hh: Add a pair_hash class, needed by
merge_transitions().
* src/graphtest/tgbagraph.cc, src/graphtest/tgbagraph.test: Add states
for transitions removal and merge_transitions().

* src/tgbaalgos/sccfilter.cc,
src/tgbaalgos/sccfilter.hh (scc_filter_states): New overload taking
a tgba_digraph and some scc_info.

* src/graph/graph.hh (trans_iterator): Add operator->() and operator
bool().
* src/tgbaalgos/sccinfo.cc, src/tgbaalgos/sccinfo.hh: New files.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgbatest/ltl2tgba.cc: Use the new dump_scc_info_dot() function.

* src/tgbaalgos/dupexp.cc, src/tgbaalgos/dupexp.hh: Return the
association between new states and old states in a vector instead of a
map.
* src/tgbaalgos/simulation.cc: Adjust.

* src/graph/graph.hh (new_states): New.
* src/tgba/tgbagraph.hh (graph_t): Make it public.
* src/tgbaalgos/simulation.cc: Get read of the acc_compl_automaton
class and replace it by a loop over all states of a tgba_digraph.
Remove some useless data structures.

* src/tgbaalgos/dupexp.cc, src/tgbaalgos/dupexp.hh: Produce
a tgba_digraph instead of a tgba_explicit_number.
* src/tgbaalgos/simulation.cc: First pass to adjust to the use of
tgba_digraph as a return of tgba_dupexp_dfs() and tgba_dupexp_bfs().
Some maps have been replaced by vectors because states are indexed,
but more simplifications could be done.

* src/tgba/tgbagraph.hh: New file.
* src/tgba/Makefile.am: Add it.
* src/graph/graph.hh: Add methods needed by tgbagraph.hh.
* src/graphtest/tgbagraph.cc, src/graphtest/tgbagraph.test: New files.
* src/graphtest/Makefile.am: Add them.

* src/graph/graph.hh, src/graph/ngraph.hh: Here.

* src/graph/graph.hh (boxed_label): If State_Data==void, inherit from
std::tuple<> and implement a data() method.
(digraph::state_data): Return by reference.
* src/graphtest/ngraph.cc, src/graphtest/ngraph.test: Test the
case where State_Data implements the spot::state interface.

* src/graph/ngraph.hh: New file.
* src/graph/Makefile.am: Add it.
* src/graphtest/ngraph.cc, src/graphtest/ngraph.test: New files.
* src/graphtest/Makefile.am: Add them

* src/graph/graph.hh, src/graph/Makefile.am, src/graphtest/graph.cc,
src/graphtest/graph.test, src/graphtest/defs.in,
src/graphtest/Makefile.am: New files.
* src/Makefile.am, configure.ac: Add graph/ and graphtest/.
* README: Mention these directories.

star_normal_form() used to be called under bounded
repetitions like [*0..4], but some of these rewritings
are only correct for [*0..].  For instance
     (a*|1)[*]      can be rewritten to    1[*]
but  (a*|1)[*0..1]  cannot be rewritten to 1[*0..1]
it would be correct to rewrite the latter as (a[+]|1)[*0..1],
canceling the empty word in a*.

Also (a*;b*)[*]     can be rewritten to    (a|b)[*]
but  (a*;b*)[*0..1]  cannot be rewritten to (a|b)[*0..1]
and it cannot either be rewritten to (a[+]|b[+])[*0..1].

This patch introduces a new function to implement
rewritings under bounded repetition.

* src/ltlvisit/snf.hh, src/ltlvisit/snf.cc (star_normal_form_unbounded):
New function.
* src/ltlvisit/simplify.cc: Use it.
* src/ltltest/reduccmp.test: Add tests.
* doc/tl/tl.tex: Document the rewritings implemented.
