* spot/graph/graph.hh: Use a temporary array to store the destination
vector if the passed range belong to the dests_ vector. Otherwise the
passed begin/end risk being invalidated when dests_ is reallocated.
* NEWS: Mention the bug.
* NEWS, README, doc/org/compile.org: Mention the option and
its effect on compilation requirements.
* configure.ac: Add the --enable-pthread option, and ENABLE_PTHREAD
macro.
* doc/org/g++wrap.in, spot/Makefile.am, spot/libspot.pc.in: Compile
with -pthread conditionally.
* spot/graph/graph.hh, spot/twa/twagraph.cc: Adjust the code to not
use thread-local variables, and let the pthread code be optional.
* .gitlab-ci.yml: Activate --enable-pthread in two configurations.
sort_edge_srcfirst_ will sort the edge with respect
to the src state, then sort each sub list with respect
to the given predicate, possibly in parallel.
* spot/graph/graph.hh: Here
Reported by Florian Renkin.
* spot/graph/graph.hh (sort_edges_of): Fix invalid read when sorting a
state without successor. Seen on core/tgbagraph.test.
The merging is (possibly) more expensive but also
merges more states when applied to all states.
* spot/graph/graph.hh: edge sorting
* spot/twa/twagraph.cc,
spot/twa/twagraph.hh: selective state merging
* tests/core/twagraph.cc: Adjusting tests
Reported by Michaël Cadilhac.
* spot/graph/graph.hh, spot/twa/twagraph.hh: Take the renaming vector
by reference, not rvalue reference. Document that
twa_graph::defrag_states may modify the vector. Keep a deprecated
version of the old prototype just in case. While there, also hide
this method from Swig.
* spot/twa/twagraph.cc: Simplify all calls to defrag_states().
* NEWS: Mention the change.
Based on report by Michaël Cadilhac.
* spot/graph/graph.hh, spot/twa/twagraph.hh (defrag_state): Clarify
that only unreachable states are meant to be removed.
* spot/twa/twagraph.hh (merge_edges): Typo in comment. Fixes#454.
* THANKS: Add Michaël.
Reported by Florian Renkin.
* spot/graph/graph.hh, spot/twa/twagraph.hh (merge_edge): Document
that it is expected that state i can only be renamed as j if j≤i.
* spot/graph/graph.hh, spot/twa/twagraph.hh, spot/twa/twagraph.cc:
Implement a dump_storage_as_dot() method.
* python/spot/__init__.py (twa_graph.show_storage): New method, above
dump_storage_as_dot().
* tests/python/twagraph-internals.ipynb: New file, with documentation
about the twa_graph internals, using show_storage() to illustrate
everything.
* tests/Makefile.am, doc/org/tut.org: Add it.
* python/spot/impl.i: Add bindings for out_iterasor, demonstrated in
the Python notebook.
* spot/twa/twa.hh: Add prop_reset(). Used in the notebook.
* NEWS: Mention the new notebook and function.
* doc/org/tut50.org: Link to the notebook.
* tests/python/ipnbdoctest.py: Adjust for twa_graph_ptr being
redefined in the spot namespace.
* spot/graph/graph.hh (internal::univ_dest_mapper): New helper class.
* spot/twa/twagraph.cc (merge_univ_dests): Simplify using
univ_dest_mapper.
(purge_unreachable_states, purge_dead_states): Add support for
alternation.
* tests/core/alternating.test: More tests.
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
new_univ_dests.
* spot/twaalgos/dot.cc, spot/twaalgos/hoa.cc, python/spot/impl.i:
Add support for universal initial states.
* spot/parseaut/parseaut.yy: Add preliminary support for
universal initial states. Multiple universal initial states
are still not supported.
* tests/core/alternating.test, tests/core/parseaut.test,
tests/python/alternating.py: Adjust tests and exercise this new feature.
* spot/graph/graph.hh: Use the sign bit of destination state X to
designate a universal edge. Store the destinations of such an edge in a
separate array, at index ~X.
* spot/graph/ngraph.hh, tests/core/graph.cc, tests/core/graph.test,
tests/core/ngraph.cc: Adjust test case to the new interface.
For #184.

assert() by SPOT_ASSERT(), or an exception, or nothing, depending
on the case.
* tests/sanity/style.test: Flag all asserts in headers.
* HACKING: Discuss assertions.
* spot/twa/twagraph.hh (edges): Do not hide from SWIG.
* spot/graph/graph.hh: Hide stuff that SWIG do not understand.
* python/spot/impl.i: Add some typemaps and fragment to
iterate over the result of twa_graph::edges().
* spot/twa/twagraph.hh (out): Do not hide from SWIG.
* spot/graph/graph.hh: Hide stuff that SWIG do not understand.
* wrap/python/spot_impl.i: Add some typemaps and fragment to
iterate over the result of twa_graph::out().
* 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.
