This implementation of direct simulation was only working on
degeneralized automata, and produce automata that are inferiors to
those output by the new direct simulation implementation (in
tgba/simulation.hh) which can also work on TGBA.  The delayed
simulation has never been reliable.  It's time for some spring
cleaning.

There is no point in degeneralizing an automaton if it can be WDBA
minimized.  Doing so will only augment the number of states and
slow down the powerset construction used by the WDBA minimization.

* src/tgbatest/babiak.test: New file.  It includes 5 formulae
which Tomáš Babiak reported Spot 0.7.1 would take over one hour to
translate if degeneralization and WDBA minimization were both
requested.
* src/tgbatest/Makefile.am (TESTS): Add it.
* src/tgbatest/ltl2tgba.cc: Do WDBA minimization before
degeneralization.  The above formulae are now all translated in a
few seconds.

Spot 0.7.1 used to need 190 acceptance conditions to translate the
188 literature formulae.  With this patch we are down to 185.
That's not an impressive, but there are only ~20 formulae that
require more than 1 acceptance conditions; hence little room for
improvement.

* src/tgbaalgos/tgbatba.cc: When degeneralizing to SBA, remove the

Note: I swapped the name of safety and guarantee when I
implemented is_safety_automaton() on 2010-03-20.  Fortunately,
is_safety_automaton() was only used where is_guarantee_automaton()
would have been correct.

automaton.

This is actually the third time I fix random_graph().  On
2007-02-06 I changed the function not to generated dead states,
but in a way that made it non-deterministic.  On 2010-01-20 I made
the function deterministic again, but it started to generate dead
states as a side effect.  This time, I'm making sure that dead
states won't come again with a test-case that we should have had
from the beginning.

* src/tgbaalgos/randomgraph.cc (random_graph): Add an extra

states indices after a random selection without actually changing

src/tgbatest/tripprod.test: Adjust to run from a subdirectory.

	* src/tgba/tgbacomplement.hh, src/tgba/tgbacomplement.cc: New
	files. The complementation algorithm.
	* src/tgba/Makefile.am: Adjust.
	* src/tgbatest/complementation.test,
	src/tgbatest/complementation.cc: New files. Test suite for the
	complementation algorithm.
	* src/tgbatest/Makefile.am: Adjust.

	columns.

* src/tgbatest/Makefile.am: Adjust.
* src/tgbaalgos/scc.hh: More documentation.
* src/tgbaalgos/scc.cc (scc_recurse): Fix computation of
acc_paths and dead_paths.  Prevent recursions in states that
have already been visited.

for ELTL.  This is a new version of the work started in 2008 with
LTL and ELTL formulae now sharing the same class hierarchy.

* configure.ac: Adjust for src/eltlparse/ and src/eltltest/
directories, and call AX_BOOST_BASE.
* m4/boost.m4: New file defining AX_BOOST_BASE([MINIMUM-VERSION]).
* src/Makefile.am: Add eltlparse and eltltest.
* src/eltlparse/: New directory.  Contains the ELTL parser.
* src/eltltest/: New directory.  Contains tests related to
ELTL (parser and AST).
* src/ltlast/Makefile.am: Adjust for ELTL AST files.
* src/ltlast/automatop.cc, src/ltlast/automatop.hh: New files.
Represent automaton operators nodes used in ELTL ASTs.
* src/ltlast/nfa.cc, src/ltlast/nfa.hh: New files.  Represent
simple NFAs used internally by automatop nodes.
* src/ltlast/allnode.hh, src/ltlast/predecl.hh,
src/ltlast/visitor.hh: Adjust for automatop.

src/ltlvisit/reduce.cc, src/ltlvisit/syntimpl.cc,
src/ltlvisit/tostring.cc: Because LTL and ELTL formulae share the
same class hierarchy, LTL visitors need to handle automatop nodes
to compile.  When it's meaningful the visitor applies on automatop
nodes or simply assert(0) otherwise.
* src/tgba/tgbabddconcretefactory.cc (create_anonymous_state),
src/tgba/tgbabddconcretefactory.hh (create_anonymous_state): New
function used by the LaCIM translation algorithm for ELTL.
* src/tgbaalgos/Makefile.am: Adjust for eltl2tgba_lacim* files.
* src/tgbaalgos/eltl2tgba_lacim.cc,

the LaCIM translation algorithm for ELTL.
* src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_lacim.cc:
Handle automatop nodes in the translation by an assert(0).
* src/tgbatest/Makefile.am: Adjust for eltl2tgba.* files.
* src/src/tgbatest/eltl2tgba.cc, src/tgbatest/eltl2tgba.test: New
files
