    stapdyn: Enable end/error probes
    
    The dyninst exit hook runs too late for us to still call anything in the
    mutatee, so the systemtap_module_exit() call which should run all of the
    end/error probes wasn't happening.
    
    Now we use a destructor function in the mutatee, so our exit path always
    runs after main() returns or after an exit() call.  Functions like
    _exit() are still problematic though.
    
    This now also makes a distinction between initializing process-local vs.
    session resources, so we are more ready for operating with multiple
    mutatees at once.  See dyninst/runtime.h for design comments.
