vf_*: fix pts values passed to the next filter
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.
