Our use of
ltl2tgba=ltl2tgba
autfilt=autfilt
...
all over the test cases comes from the time where those tools were not
in PATH and we actually had something like
ltl2tgba=../../bin/ltl2tgba
autfilt=../../bin/autfilt
But today that is useless, and we prefer to write ltl2tgba rather than
$ltl2tgba, so let's remove this old cruft.

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/stutter-tgba.test: Adjust to expect smaller automata.
Fixes#164.
* spot/twaalgos/stutter.hh, spot/twaalgos/stutter.cc: Implement
the determinization, while keeping it optional.
* NEWS: Mention the change.
* tests/core/ltl2dstar.test, tests/core/stutter-tgba.test: Add
test cases.
