test case.
* doc/org/tut24.org: Adjust example.

This mixes the subset construction (for 1-state rejecting SCCs) and
the breakpoint construction (for larger rejecting SCCs).  The
algorithm should probably be rewritten in a cleaner and more efficient
way, but that should do for a first version.  It should be easy to
extend it to support Büchi acceptance (since the breakpoint
construction works for this) when we need it.

* spot/twaalgos/Makefile.am: Add them.
* python/spot/impl.i: Add bindings.

The only missing point is that the HOA parser cannot deal with multiple
universal initial states, as seen in parseaut.test.

* spot/graph/graph.hh (new_univ_dests): New function, extracted from...
(new_univ_edge): ... this one.
* spot/twa/twagraph.hh (set_univ_init_state): Implement using

are still not supported.

tests/python/alternating.py: Adjust tests and exercise this new feature.

Currently this only reads universal branches.  The parser (and the
automaton code) do not support universal initial states.

the no-univ-branch/!univ-branch change in HOA 1.1.
* tests/python/alternating.py: Read the output of print_hoa.
