marks while preserving state-based acceptance.  Add a new argument
to specify if all useless mark have to be removed, like for scc_filter.
* src/twaalgos/simulation.cc: Use the new parameter.
* src/twaalgos/postproc.cc: Likewise.  Also call do_scc_filter even

The previous code was sometime doing the work of remove_fin() in
addition to complementing the acceptance conditions.  This separate
the two operations clearly.  Also the specialized code for
complementing weak automata is now a specialized code for remove_fin()
on weak automata.

* src/twaalgos/dtgbacomp.hh, src/twaalgos/dtgbacomp.cc: Rename as ...
* src/twaalgos/complement.hh, src/twaalgos/complement.cc: ... these.
* src/twaalgos/Makefile.am: Adjust.
* src/twaalgos/complement.hh (dtgba_complement): Rename as ...
(dtwa_complement): ... this, and restrict the purpose to completion
and accetance complementation.  Further acceptance simplification
can be done with remove_fin() and to_generalized_buchi().
* src/twaalgos/remfin.cc (remove_fin): Specialize handling of weak
automata using the code that was originally in dtgba_complement().
Also mark the output as state-based when the input has to Inf.
* src/twaalgos/postproc.cc, src/twaalgos/postproc.hh: Make sure
scc_filter is always called after to_generalized_buchi().

it.

* wrap/python/spot.py: Python 3.5 reports some unexpected SystemError
messages when the stack of iterator(...(iterator(generator))) we build
for random LTL generation raises a StopIteration.  The messages are
attached either to delete_formula or delete_randltlgenerator, claiming
that these functions exit with an error; but I have checked that they
do not.  I've been unable to understand the cause of the issue.
Replacing the generator by an iterator at least fixes the problem in a
way that is transparent for our API.
* wrap/python/tests/randltl.ipynb: Adjust expected formulas.

* wrap/python/spot_impl.i: Map null formulas to None.
* wrap/python/tests/randgen.py: New file.
* wrap/python/tests/Makefile.am: Add it.

src/twa/bdddict.hh (unregister_all_typed_variables, oneacc_to_formula,
register_acceptance_variables): Remove these unused methods.
