Right now, destroy() just executes "delete this". But in a later version, we will rewrite tgba_explicit so that it does not allocate new states (and the destroy() method for explicit state will do nothing). * src/tgba/state.hh (state::destroy): New method, to replace state::~state() in the future. (shared_state_deleter): New function. * src/evtgba/product.cc, src/evtgbaalgos/reachiter.cc, src/evtgbaalgos/save.cc, src/evtgbaalgos/tgba2evtgba.cc, src/tgba/tgba.cc, src/tgba/tgbaproduct.cc, src/tgba/tgbareduc.cc, src/tgba/tgbasafracomplement.cc, src/tgba/tgbasgba.cc, src/tgba/tgbatba.cc, src/tgba/tgbaunion.cc, src/tgba/wdbacomp.cc, src/tgbaalgos/cutscc.cc, src/tgbaalgos/emptiness.cc, src/tgbaalgos/gtec/ce.cc, src/tgbaalgos/gtec/explscc.cc, src/tgbaalgos/gtec/gtec.cc, src/tgbaalgos/gtec/nsheap.cc, src/tgbaalgos/gv04.cc, src/tgbaalgos/magic.cc, src/tgbaalgos/minimize.cc, src/tgbaalgos/ndfs_result.hxx, src/tgbaalgos/neverclaim.cc, src/tgbaalgos/powerset.hh, src/tgbaalgos/reachiter.cc, src/tgbaalgos/reducerun.cc, src/tgbaalgos/reductgba_sim.cc, src/tgbaalgos/reductgba_sim_del.cc, src/tgbaalgos/replayrun.cc, src/tgbaalgos/safety.cc, src/tgbaalgos/save.cc, src/tgbaalgos/scc.cc, src/tgbaalgos/se05.cc, src/tgbaalgos/tau03.cc, src/tgbaalgos/tau03opt.cc: Adjust to call "s->destroy()" instead of "delete s". * src/saba/sabacomplementtgba.cc, src/tgba/tgbakvcomplement.cc: Pass shared_state_deleter to the shared_ptr constructor, so that it calls destroy() instead of delete.
