clone for M.
* src/ltlvisit/contain.cc (reduce_tau03_visitor): Remove
the stronger rules for R and M. They were wrong.
* src/ltltest/reduccmp.test: Test a simpple counterexample.
* src/ltlvisit/reduce.cc (reduce_visitor): Add the following
implication rewriting rules:
a M (b M c) = a M c if a implies b.
a M (b R c) = a M c if a implies b.
a R (b R c) = a R c if a implies b.
a R (b M c) = b M c if b implies a.
a M (b M c) = b M c if b implies a.
The latter rule was fixed from an incorrectly copied&pasted
rule for a M (b R c) = b R c if b implies a (this is wrong).
* src/ltltest/reduccmp.test: Add more tests.
* src/ltlvisit/basicreduce.cc: Perform the following reductions:
(a R b) | Gb = a R b
(a M b) | Gb = a R b
(a U b) & Fb = a U b
(a W b) & Fb = a U b
* src/ltltest/reduccmp.test: Test them.
* src/ltlvisit/basicreduce.cc: Perform the following reductions:
(a U b) & (c W b) = (a & c) U b
(a W b) & (c W b) = (a & c) W b
(a R b) | (c M b) = (a | c) R b
(a M b) | (c M b) = (a | c) M b
* src/ltltest/reduccmp.test: Test them.
* src/ltlvisit/basicreduce.cc: Perform the following reductions.
a R (b & F(a)) = a M b
a M (b & F(a)) = a M b
a R Fa = Fa
a M Fa = Fa
a R b & Fa = a M b
a R b & a M c = a M (b & c)
a M b & a M c = a M (b & c)
* src/ltltest/reduccmp.test: More tests.
* src/ltlvisit/basicreduce.cc: Perform the following reductions.
a U (b | Ga) = a W b
a W (b | Ga) = a W b
a U b | Ga = a W b
a U b | a W c = a W (b | c)
a W b | a W c = a W (b | c)
a U Ga = Ga
a W Ga = Ga
* src/ltltest/reduccmp.test: More tests.
* src/ltlast/binop.cc, src/ltlast/binop.cc: Add support for
these new operators.

src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_lacim.cc:
Add support for W and M.
* src/tgbatest/ltl2neverclaim.test: Test never claim output
using LBTT, this is more thorough. Also we cannot use -N
any more in the spotlbtt.test.
* src/tgbatests/ltl2tgba.cc: Define M and W for ELTL.
* src/tgbatest/ltl2neverclaim.test: Test W and M, and use
-DS instead of -N, because lbtt-translate does not want
to translate these operators for tools that masquerade as Spin.
New function, performing LTL reduction a la tauriainen.03.a83.
* src/ltltest/equals.cc, src/ltltest/reduc.cc: Add support for
the new reduction.
* src/ltltest/reduc.test: Cut the test in half, and additionally
test the new reduction.
* src/ltltest/reduccmp.test: Run on the new reduction.

test for reduction of automata.
* src/tgbaalgos/reductgba_sim_del.cc, src/tgbaalgos/reductgba_sim.cc,
