[Clp] Memory leak after startFastDual

[Sebastian Theophil]

Hi John,

there seems to be a memory leak caused by
OsiClpSolverInterface::startFastDual:

OsiClpSolverInterface solver;
...

{
    OsiClpSolverInterface solver2(solver);
    // make changes to solver2
    solver2.startFastDual(2);
    solver2.resolve();
} // memory leak

OsiClpSolverInterface::startFastDual passes a pointer to stuff_ into
ClpSimplex::startFastDual2 which creates a saveCosts_ array inside
stuff_ that is never freed unless stopFastDual is called. The
ClpNodeStuff dtor doesn't delete the array, but probably should. 

Regards
Sebastian
