* wrap/python/spot.i: Rename to...
* wrap/python/spot_impl.i: ...this, and import spot_impl from spot.py so
that it is not needed to recompile everything when modifying python
code.
* wrap/python/spot.py: Adding python functions to mirror the
functionalities found in src/bin.
* src/bin/common_r.cc: Move simplification level...
* src/ltlvisit/simplify.hh: ... here as a constructor of
ltl_simplifier_options, to make it available in wrap/python.
* src/bin/ltlfilt.cc: Set simplification level using the new
ltl_simplifier_options constructor.
* src/bin/randltl.cc: Move most of the code...
* src/ltlvisit/randomltl.cc, src/ltlvisit/randomltl.hh: ... here, as a
class named randltlgenerator.
* wrap/python/tests/bddnqueen.py, wrap/python/tests/minato.py: Avoid
calling bdd_init twice by moving 'import spot' after bdd initialization.

A Fin() terms with multiple sets should not appear under an And.
* src/tgba/acc.cc (is_dnf): Fix it.
* src/tgbatest/acc.cc, src/tgbatest/acc.test: Augment test case.
This way we have for instance
(Inf(1) | Fin(2)) & (Fin(1) | Inf(3)) & Inf(0)
converted into just
(Fin(1) & Fin(2) & Inf(0)) | (Inf(0)&Inf(1)&Inf(3))
while previously we would produce 4 terms:
(Fin(2) & Fin(1) & Inf(0)) | (Fin(2) & (Inf(0)&Inf(3)))
| (Fin(1) & (Inf(0)&Inf(1))) | (Inf(0)&Inf(1)&Inf(3))
* src/tgba/acc.cc (to_dnf): Recode it.
* src/tgbatest/acc2.test: Adjust.
Because scc_info does not perform a full emptiness check, it is not
always able to tell whether an SCC is accepting if the acceptance
condition use Fin primitives. This introduce is_rejecting_scc() in
addition to to is_accepting_scc(). Only one of them may be true, but
they can both be false if scc_info has no idea whether the SCC is
accepting.

is_rejecting_scc().

tests.
* src/tgbatest/sccdot.test: New test case.
* src/tgbatest/Makefile.am: Add it.
* src/tgbaalgos/simulation.cc (direct_simulation): Do not store the
original_ automaton as a reference. Otherwise with LTO (+ probably NRVO)
we get a situation where the result automaton (that will be stored in
original_) copies the properties of itself.
Fixes#59.

src/tgbaalgos/sccfilter.cc, src/tgbaalgos/simulation.cc: Throw an
exception if an unsupported type of acceptance is received.
* src/tgba/acc.cc, src/tgba/acc.hh: Move the strip() routine from
acc_cond into acc_cond::mark_t, and the strip() routine from
cleanacc.cc into acc_cond::acc_code. Introduce helper functions
to create inf()/fin()/t()/f() at the acc_code level.

from acc_code.

* src/tgbaalgos/sccfilter.cc, src/tgbatest/acc.cc: Adjust the
use mark_t::strip().

to work with generic acceptance.
Instead of adding one set per term in the DNF, reuse the
removed Fin(x) sets as Inf(x) sets.
* src/tgbaalgos/remfin.cc: Here.
* src/tgbatest/remfin.test: Additional test.
* src/tgba/acc.cc, src/tgba/acc.hh (complement): New method.

have the same acceptance condition.

Make sure the constructors with perfect forwarding for states and
transitions do not take the place of copy constructors. Thanks to Akim
Demaille for its help. This should fix a bug observed by Joachim Klein
and David Muller.
* src/graph/graph.hh: Disable forwarding constructors for states and
transitions if the first argument is a subclass of the current class.
