Introducing the new game interface
to ltlsynt.
ltlsynt now also uses direct strategy deduction
and formula decomposition.

Introduce a new, uniform way to create and solve
games.
Games can now be created directly from specification
using creat_game, uniformly solved using
solve_game and transformed into a strategy
using create_strategy.
Strategy are mealy machines, which can be minimized.

spot/twaalgos/postproc.hh: Introduce options Buchi and
GeneralizedBuchi. The latter is similar to TGBA but the former differs
from BA in that it does not imply state-based acceptance, since that
can be specified separately. Also all other acceptance types are not
abbreviated, so those new names make more sense.
* NEWS: Mention that.
* spot/twaalgos/postproc.cc, spot/twaalgos/translate.cc: Adjust
to support Buchi and GeneralizedBuchi without breaking BA and TGBA.

* spot/twaalgos/split.cc, spot/twaalgos/split.hh: No longer contains
the splits necessary for for synthesis, moved to
spot/twaalgos/synthesis.cc, spot/twaalgos/split.hh Split is now faster
and reduces the number of intermediate states, reducing the overall
size of the arena
* spot/misc/game.cc, spot/misc/game.hh: Renaming propagate_players to
alternate_players.

properties.

of gates as well as different encoding types have been added.
* bin/ltlsynt.cc: Make the new options for print-aiger available.
* tests/core/ltlsynt.test: Adjust tests.
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.

This class was a simple wrapper on top of twa_graph_ptr, but it's
easier to simply use a twa_graph_ptr with a "state-player" property
instead, this way we will be able to modify the automata I/O routines
to support games directly.
* spot/misc/game.cc, spot/misc/game.hh: Rewrite the solver and
pg_printer interface.
* bin/ltlsynt.cc: Adjust.

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.
* NEWS: Mention the fix.
Fixes#15.
* spot/twaalgos/minimize.hh, spot/twaalgos/minimize.cc
