Many video filters failed to calculate or even just pass through pts values for their output frames. Fix this, and also make the two remaining filters that called vf_next_put_image() twice for the same input frame (vf_softpulldown, vf_telecine) use vf_queue_frame() so that e.g. framestepping properly sees both frames. Changed filters: vf_bmovl, vf_detc, vf_divtc, vf_filmdint, vf_ivtc, vf_lavc, vf_phase, vf_pullup, vf_softpulldown, vf_telecine, vf_tile, vf_tinterlace.
