As observed in #188, the smaller.hoa automaton is made only of
1-state/1-self-loop SCCs, for which calling remove_fin is a complete
waste of time.  This patch alone (i.e., without the other changes
suggested by #188) improves the run time of

% autofilt -q --is-unambiguous smaller.hoa

from 38s to 0.05s.

* spot/twaalgos/sccinfo.cc: If a single-state SCC has undeterminate SCC
and only one self-loop, then it is necessarily rejecting.
* NEWS: Mention the change.

Rename tgba_digraph as twa_graph.

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.

node_ vector.   Tidy the scc_node structure that that its member

This involves reimplementing some algorithms using tgba_digraph, and
implementing an explicit product that takes two tgba_digraphs and
produces a tgba_digraph.

This is a huge patch, that took over a month to complete.  The bit sets
are currently restricted to what 'unsigned can store', but it should be
easy to extend it to 'uint64_t' should we need it.

* NEWS: Update.
* src/tgba/acc.hh: New file.

* src/tgba/tgbakvcomplement.cc, src/tgba/tgbakvcomplement.hh,
src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete.  The KV
complementation is too slow to be used in practice, and I somehow broke
it during the conversion to bitsets.  The tgba->sgba conversion was only
used for the KV complementation, and should be better redone on
tgba_digraph_ptr should it be needed again.

This gets rid of many state*/int conversions.  We now use scc_info
instead of scc_map.  Finally the loops are now all 0-based.

A type such as 'const tgba_digraph*' and 'tgba_digraph*' are replaced
by 'const_tgba_digraph_ptr' and 'tgba_digraph_ptr'.  Additionally 'new
tgba_digraph(...)' is replaced by 'make_tgba_digraph(...)'.

This convention is followed by all automata types. Those smart
pointers should normally be passed by const reference as input of
function to avoid the atomic increments/decrements, but I probably
missed a few, as this huge patch took me nearly 12h.

This is a huge patch.  tgba_digraph are equiped with some boolean
properties that can be used to indicate whether they represent SBA
(and will carry more informations later).  All algorithms that produce
or use sba_explicit_* automata are changed to use tgba_digraph.
postproc has been rewritten using only tgba_digraph, and this required
changing the return types of many algorithms from tgba* to
tgba_digraph*.
