don't change ode options.havejacfun (reverts part of e1788b1a315f) * ode15i.m, ode15s.m: Revert change of havejacfun -> havejacfcn field name used in options struct that is passed to __ode15__. If we change that field, we'll also need to change __ode15__, possibly providing a path for backward compatibility?
