* bin/ltlsynt.cc: Use it.
* doc/org/ltlsynt.org: Document it.

For now, ltlsynt only handles LTL realizability. It uses a reduction to
parity game followed by Calude et al.'s reduction from parity game to
reachability game.

* bin/ltlsynt.cc, bin/Makefile.am, bin/man/ltlsynt.x,
bin/man/Makefile.am, bin/.gitignore: New binary.

* spot/misc/game.cc, spot/misc/game.hh, spot/misc/Makefile.am: Parity
game wrapper for parity automata + reachability game interface from
Calude et al.'s paper.

parity_product_or constructs the sum of two parity automata and it keeps
the parity.

* spot/twaalgos/parity.cc, spot/twaalgos/parity.hh: Here.
* tests/core/parity.cc: Add tests here.

Some states can become identical once their history matrix are
cleaned. These states are merged and only store the cleaned matrix.

* spot/twaalgos/parity.cc: Here.

The history matrix of size n*m is replaced by couples of vectors with a
total size of n + m. These couples of vectors are simplified
representations of the history matrices, they ecnode the exact same
data. They are cached as well as the method to get the next history
matrix using the acc_sets and the current history matrix.

* spot/twaalgos/parity.cc: Here.

Compute the synchronized product of two parity automata, this product
keeps the parity acceptance.

* spot/twaalgos/parity.cc, spot/twaalgos/parity.hh: Here
* tests/core/parity.cc: Add tests for spot::parity_product()

Merge the acceptance sets of a parity acceptance with the same priority
level to simplify this acceptance.

* spot/twaalgos/parity.cc, spot/twaalgos/parity.hh: Here
* tests/core/parity.cc: Add tests for spot::cleanup_parity_acceptance()

These functions colorize automata with parity acceptance. They output
parity automata.

* tests/core/parity.cc: Add tests for spot::colorize_parity()
* tests/python/parity.ipynb: Add documentation about
spot::colorize_parity()

This function changes the parity acceptance of an automaton.

* spot/twaalgos/parity.cc, spot/twaalgos/parity.hh: Here
* python/spot/impl.i: Add spot/twaalgos/parity.hh
* spot/twaalgos/Makefile.am: Add spot/twaalgos/parity.{cc,hh}

spot::change_parity()
* tests/Makefile.am: Add tests/core/parity.{cc,hh} and
tests/python/parity.ipynb
* doc/org/tut.org: Add the html page of tests/python/parity.ipynb

This function checks whether an automaton is colored, an automaton
is said to be colored iff all the transitions belong to exactly one
acceptance set.

* spot/twaalgos/iscolored.cc, spot/twaalgos/iscolored.hh: Here.
* spot/twaalgos/Makefile.am: add spot/twaalgos/iscolored.{cc,hh}
