    Make sure the neverclaim parser works on the output of spin and · fe1f59cd

    * src/neverparse/neverclaimparse.yy: Accept multiple labels
    for the same state.  Honor accepting states.  Forward parse
    error from the parser used for guards.  Accept "false" as a
    single instruction for a state.
    * src/neverparse/neverclaimscan.ll: Recognize "false" specifically,
    and remove the ";" hack.
    * src/tgba/tgbaexplicit.cc
    (tgba_explicit_string::~tgba_explicit_string): Adjust not to
    destroy a state twice.
    * src/tgba/tgbaexplicit.hh
    (tgba_explicit_string::add_state_alias): New function.
    * src/tgbatest/defs.in (SPIN, LTL2BA): New variables.
    * src/tgbatest/neverclaimread.test: Check error messages for
    syntax errors in guards.  Make sure we can read the output
    of `spin -f' and `ltl2ba -f' on a few test formulae.
