about 0 states anymore.

Because gal2c generates some C++ sources that do not match our coding

Reported by Juraj Major.

* spot/twa/twa.hh: check num_sets() in prop_state_acc() so we do not
have to set it in set_acceptance(), causing trouble if set_acceptance()
is called multiple times.

* tests/Makefile.am: Add it.
* THANKS: Add Juraj.
* NEWS: Mention the bug.

* spot/twaalgos/remfin.cc: Do not add a sink states to deterministic
weak automata, and actually apply the "weak" Fin-removal to any weak
automaton.
* tests/core/explprod.test: Add a test case for the previous patch,
but that used to fail because of this bug.
* NEWS: Mention the bug.

* spot/parseaut/public.hh, spot/parseaut/scanaut.ll: When parsing
automata read from some given FD, do not close the file descriptor, as
the caller is likely to already close it, and closing FDs twice is very
bad.  This seems to have be the root of some issue we had with recent
jupyter versions, were 0MQ would crash with "Bad file descriptor"
messages.  Also do not close stdin while we are at it.
* NEWS: Mention the bug.
