spot/twa/twaproduct.cc, spot/twaalgos/couvreurnew.cc,
tests/python/bugdet.py: Here.

* spot/twaalgos/dot.cc: Implement.

* spot/gen/automata.cc, spot/gen/automata.hh, bin/genaut.cc: Rename
the enum, function, and command-line option.
* tests/core/genaut.test, tests/python/gen.ipynb, tests/python/gen.py:
Adjust test cases.
* doc/org/genaut.org: Adjust doc.

This addresses part of #35, and is just a generalization of the rules
from 646c5170 for #263 (hence, no new documentation).

* spot/tl/simplify.cc: Implement this.
* tests/core/reduccmp.test: Add test cases.
* tests/core/stutter-tgba.test: Adjust to expect smaller automata.

Fixes #108.

* spot/tl/simplify.cc: Implement the reduction.
* doc/tl/tl.tex, NEWS: Document it.
* tests/core/reduccmp.test: Test it.

Fixes #277.

* spot/twaalgos/ltl2tgba_fm.cc: Improve the translation of f U g
when f is universal.  Suggested by Maximilien Colange.
* tests/core/ltl2tgba.test: Test it.

As suggested in #263.

* spot/gen/formulas.cc, spot/gen/formulas.hh, bin/genltl.cc: Implement
these options.
* tests/core/genltl.test: Use them.
* NEWS: Mention them.

For #263, reported by Mikuláš Klokočka.

G(a & Xe1 & F(b & e2)) = G(a & e1 & Fb & e2)
F(a | Xu1 | G(b | u2)) = F(a | u1 | Gb | u2)

* spot/twaalgos/remfin.cc: Replace the complex enum
definition by a plain enum that is almost not used.

* spot/twaalgos/remfin.cc (remove_fin_impl): Apply the Rabin strategy
before the Streett one.

The generalization to Streett-like of 7b5b8f34 was incomplete for this
case.  Thanks to František Blahoudek for reporting the bug.
Fixes #279.

This way in 2.5 we can make 'a' the default, and tell people to use
SPOT_DOTDEFAULT=A if they want the old behavior in both 2.4 and 2.5.
