neverclaims it outputs.

fe1f59cd30 Make sure the neverclaim parser works on the output of spin and 
ltl2ba.

* 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.

498b44f742 Revert "Add never claim parser." 
Such changes should not be pushed to master before they are finished
(this doesn't pass distcheck).

This reverts commit 9aaa638b27.
