This restricts the time spent in translating sub-formulas for
implication tests by limiting the associated automata to 64 states by
default. Doing so this does worsen any test case, and actually remove
all calls the BuDDy's GC in bdd.test.

Fixes#403.
* spot/twaalgos/cleanacc.cc (simplify_complementary_marks_here):
Assume that two colors are complementary in a broad sense, i.e., on is
present if (but not only if) the other is missing before applying
those rewritings. Technically, this is usually not necessary, because
the changes done in #418 will cause such "covering-the-full-automaton"
pair of colors to be disjoint so complementary in a strict sense. It
might make a difference (this is not tested) in presence of reused
colors which #418 cannot remove. In any case, it's simply less code
to implement the broad sense.

reduced to two states with recent optimizations.
This fixes issue #418.

Use ltldo:... instead of error:... and warning:... and also improve
the diagnostic displayed after a translation failure to mention the
tool and formula.
Incidentally, this fixes a spurious test case failure observed by
Philipp Schlehuber on CentOS7.7 where glibc 2.17 is installed. With
this system, when posix_spawn() starts a binary that does not exist,
it returns success and let the child die with exit code 127. On more
recent glibc, posix_spawn() manages to return execve()'s errno, as if
the child had not been created. We handle those two different ways to
fail, but before this patch one used to print "error:..." and the
other "ltldo:...".
* bin/ltldo.cc: Display the program_name in error message. Display
the command name and formula on translation failure.
* tests/core/ltldo.test: Adjust test case.

simplifying certain patterns, as noted in the first comment of
issue #405.

Juraj Major reported a case with 32 APs where ltlcross would take
forever to gather statistics. It turns out that for each edge,
twa_sub_statistics was enumerating all compatible assignments of 32
APs. This uses bdd_satcountset() instead, and also store the result
in a long long to avoid overflows.

On some architectures this test fails due to several
reasons:
- missing headers
- use of valueAt instead of count in ConCS. Indeed,
valueAt acts similarly to count but avoids some validity
check that are required when the hashmap is growing.
This patch also:
- removes inaccurate comments from bricks.test.
- test more features for hashset.

tests/core/bricks.cc,
tests/core/bricks.test: Here.
