state-based.

This is a huge patch, that took over a month to complete. The bit sets
are currently restricted to what 'unsigned can store', but it should be
easy to extend it to 'uint64_t' should we need it.

complementation is too slow to be used in practice, and I somehow broke
it during the conversion to bitsets. The tgba->sgba conversion was only
used for the KV complementation, and should be better redone on
tgba_digraph_ptr should it be needed again.

Again instead of calling ltl2tgba dozen of times with different options
for various formulas, this implements a single executable that reads
formulas from a file, translate them using the different setups, and
dump statistics for comparison. Valgrind now only has to be started
once.

ltl2tgba.test using to take more than 15min. We are now down to
25sec.
* src/tgbatest/checkpsl.cc: New file.
* src/tgbatest/Makefile.am: Add it.
* src/tgbatest/ltl2tgba.test: Adjust.
This translator algorithm is seldom used in practice because we work
with explicit automata everywhere, and this is only useful to build
symbolic automata. Furthermore, the symbolic automata produced by this
algorithm are larger (when looked at explicitly) than those produced by
ltl2tgba_fm or other explicit translators.
The nice side effect of this removal is that we can also remove a lot of
supporting classes, that were relying a lot on BDDs.
