* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite wihtout assuming
that the product of two accepting SCCs is accepting, Also use
the result of is_accepting_scc()/is_rejectng_scc() when available.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/sccinfo.hh: Make it
possible to check the acceptance of a unique SCC.
* tests/core/unambig.test: Add more test cases.
spot::acc_cond::mark_t is implemented as a bit vector using a single
unsigned, and implicit conversions between mark_t and unsigned may be
confusing. We try to use the proper interface.

is_useful_scc() in states_on_acc_cycle_of().
* spot/twaalgos/sccinfo.hh, spot/twaalgos/sccinfo.cc: Add an optional
argument to abort on accepting SCC, to not keep track of SCC states,
and some one_accepting_scc() method.

scc_info::used_acc() and spot::info::used_acc_of() have been renamed to
scc_info::marks() and scc_info::marks_of().
scc_info::acc() has been renamed to (the already existing and redundant)
scc_info::acc_sets_of().
Old names have been deprecated.

(determine_unknown_acceptance): Do not complain about
not supporting alternating automata if there is not
indeterminate acceptance.
* spot/twaalgos/stats.cc: Fix a bug were %[iw]c was
read as %[iww]c.
* tests/core/alternating.test: Test is_inherently_weak_scc() and
is_weak_scc().
* python/spot/impl.i: Add missing python bindings
for isweakscc.hh.
* spot/twaalgos/sccinfo.hh, spot/twaalgos/sccinfo.cc: Take
a filter function as optional argument.

* NEWS: Mention the new feature.
This is motivated by some upcoming patch by Heňo.
* spot/twaalgos/sccinfo.hh (edges_of, inner_edges_of): New methods.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/strength.cc: Use them.
* spot/twa/twagraph.hh (edge_number): Add an overload.
* python/spot/impl.i: Bind the new methods.
* tests/python/sccinfo.py: Add tests.
* NEWS: Mention the changes.
* bin/autfilt.cc, spot/twaalgos/isweakscc.cc, spot/twaalgos/remfin.cc,
spot/twaalgos/sccinfo.cc: Use mask_keep_accessible_states instead of
mask_keep_states.
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.
* NEWS: Mention the change.
* src/: Rename as ...
* spot/: ... this, adjust all headers to include <spot/...> instead of
"...", and adjust all Makefile.am to search headers from the top-level
directory.
* HACKING: Add conventions about #include.
* spot/sanity/style.test: Add a few more grep to catch cases
that do not follow these conventions.
