- rename all clip_top, clip_left, clip_color... to hili_xxxx. that

  "clip" thing has caused too much confusion already since these variables
  define a highlight area.
- add overlay offset support to video_out.c/alphablend/vo drivers
- use overlay offset to implement proper croping of frames when vo
  driver doesn't support it
- add clipping checks to alphablend to avoid buffer overflow, buffer
  "underflow" and wrapping.
- increase vo api number
- note: dxr3 support is incomplete about overlay offset
