sink as successor.
* spot/twaalgos/strength.hh, spot/twaalgos/strength.cc
(is_terminal_automaton): Add an option to ignore trivial SCC as we did
before, since it matters for deciding membership to the guarantee
class.

ignoring trivial SCCs.

* tests/core/hierarchy.test: New file.
* tests/Makefile.am: Add it.
* NEWS: Mention the new options.
Algorithms that remove transitions can turn a non-deterministic
automaton into a deterministic one, so we need to be able to specify
that determinism can be improved (as opposed to preserved).
* spot/twa/twa.hh (twa::prop_set::improve_det): New attribute.
(twa::prop_keep, twa::prop_copy): Honor it.

spot/twaalgos/strength.cc, spot/twaalgos/stutter.cc,
spot/twaalgos/totgba.cc: Adjust calls to prop_keep() and
prop_copy().

and output for it.
* spot/twaalgos/strength.cc,

on an alternating automaton.

output.
* NEWS, doc/org/hoa.org, doc/org/concepts.org: Document it.
* python/spot/__init__.py (automata): Do not create a session for
every command, this is only needed if automata() is run with a timeout
parameter.
* python/ajax/spotcgi.in: Adjust exclude the main process from
the process group, so that only children are killed on SIGALRM.
* NEWS: Mention the bug.

* NEWS: Mention the bug.
This version has optimization for explicit twa, and also for weak and
terminal (depending on whether an accepting run is requested) automata.
* spot/twaalgos/couvreurnew.hh, spot/twaalgos/couvreurnew.cc,
spot/twaalgos/Makefile.am: New files for the new algorithm.

Compilation of each header file alone, as a safety check, was removed
when introducing "#pragma once" because we did not have to check for
possible double inclusion. However we still need to compile each
header to make sure they are self-contained.
* tests/sanity/includes.test: Compile each header.
* tests/run.in: Export various compiler and directory flags.
* spot/twaalgos/emptiness_stats.hh, spot/misc/mspool.hh,
spot/misc/fixpool.hh: Include <spot/misc/common.hh>.
* spot/misc/common.hh: Include <cassert>.
* NEWS: Mention the fixed headers.
